Subject: The Role of Vitamin B12 in Energy Production

The Role of Vitamin B12 in Energy Production

Vitamin B12, or cobalamin, is crucial for red blood cell production, DNA synthesis, and nervous system health. Among its many roles, one of the most vital is its contribution to energy production and metabolism. This article delves into how Vitamin B12 affects energy levels, with a particular focus on its importance for vegetarians and vegans.

Understanding Vitamin B12

Vitamin B12 is a water-soluble vitamin that is naturally found in animal products such as meat, dairy, and eggs. It is primarily responsible for converting food into ATP (adenosine triphosphate), which the body uses for energy. B12 is also crucial in the formation of red blood cells, which carry oxygen to every part of the body, and in maintaining the health of nerve cells.

The Science Behind Energy Production

Role in Metabolism

Vitamin B12 is a key player in metabolism, a complex set of chemical reactions in our body that convert food into energy. One of the primary ways B12 contributes to metabolism is through its involvement in the Krebs cycle, a series of reactions that produce ATP (adenosine triphosphate), the body's primary energy currency. During the Krebs cycle, Vitamin B12 helps convert fats and proteins into energy, ensuring that the body has a constant supply of fuel to perform everyday tasks.

DNA Synthesis and cell division

Vitamin B12 is also essential for DNA synthesis and cell division. It works closely with folate (Vitamin B9) to synthesize DNA during cell division. Rapidly dividing tissues, such as red blood cells, require an adequate supply of B12. A deficiency in this vitamin can lead to megaloblastic anemia, a condition where red blood cells are larger than normal and not as effective in transporting oxygen, thereby causing fatigue and weakness.

The Challenge for Vegetarians and Vegans

B12 Sources

One of the significant challenges for vegetarians and vegans is getting enough Vitamin B12, as it is predominantly found in animal products. Plant-based diets generally lack this vitamin, putting individuals at risk of deficiency. However, several fortified foods and supplements can help prevent this deficiency.

Fortified Foods and Supplements

Many plant-based milk alternatives, breakfast cereals, and nutritional yeasts are now fortified with Vitamin B12. For instance, a cup of fortified soy milk can provide about 50% of the daily recommended intake of B12. Additionally, B12 supplements are readily available and can be an effective way for vegetarians and vegans to ensure they get their daily dose. It's crucial to choose a supplement that meets the dietary needs and preferences of the individual.

Symptoms of Deficiency

A lack of Vitamin B12 can result in various health problems like fatigue, weakness, constipation, loss of appetite, and weight loss. In severe cases, it may lead to neurological issues such as numbness and tingling in the hands and feet, balance difficulties, depression, confusion, and memory loss. Given these risks, it's essential for vegetarians and vegans to monitor their B12 levels.

Benefits of Adequate B12 Intake

Enhanced Energy Levels

Adequate intake of Vitamin B12 can significantly enhance energy levels. Since B12 is involved in converting food into ATP, sufficient levels of this vitamin can help ensure that the body efficiently produces and uses energy. Individuals who maintain appropriate B12 levels often report feeling more energetic and less fatigued.

Improved Metabolic Function

By ensuring a sufficient supply of B12, vegetarians and vegans can support their metabolic functions. A well-functioning metabolism is crucial for maintaining body weight, supporting muscle function, and ensuring overall vitality. Improved metabolic function also means better handling of the foods consumed, leading to more stable energy levels throughout the day.

Better Mental Health

Vitamin B12 is essential for producing neurotransmitters that regulate mood. Adequate levels of B12 can help prevent mental health issues such as depression and brain fog, which are often associated with fatigue and low energy levels. Regular intake of B12, either through diet or supplements, can contribute to better mental clarity and emotional well-being.

Optimal Nervous System Function

B12 is crucial in maintaining the myelin sheath, a protective coating around nerves. A healthy nervous system ensures that signals travel efficiently between the brain and the rest of the body. This not only helps in preventing neurological issues but also ensures that the body's energy systems operate smoothly.

How to Ensure Adequate B12 Intake

Regular Blood Tests

For vegetarians and vegans, regular blood tests are an effective way to monitor B12 levels. These tests can help identify a deficiency early on, allowing individuals to take corrective measures before any severe symptoms manifest.

Balanced Diet

A well-rounded, balanced diet that includes fortified foods can help meet the daily recommended intake of Vitamin B12. Incorporating a variety of B12-fortified foods into every meal ensures a steady supply of this vital nutrient.

Considering Supplements

For those who struggle to get enough Vitamin B12 through diet alone, supplements are an excellent option.

Choosing the Right Supplement: Methyl B12

When selecting a Vitamin B12 supplement, methylcobalamin, or methyl B12, is often recommended as the best form. It has superior bioavailability compared to cyanocobalamin, making it easier for the body to absorb and utilize. Methyl B12 doesn't need conversion in the body to be effective, leading to quicker uptake and immediate benefits.

For vegetarians and vegans at higher risk of B12 deficiency, methyl B12 is especially beneficial for maintaining optimal B12 levels effectively. Including this form in your supplement routine can boost energy, mental clarity, and support metabolic and nervous system functions.

Awareness and Education

Raising awareness about B12 is key for vegetarians and vegans to prevent deficiencies. Health programs can educate on maintaining adequate levels through diet and supplements.

Are You Ready For More Energy?

Vitamin B12's role in energy production and metabolism is indisputable. Vegetarians and vegans can struggle to get enough B12 from plant-based diets, but fortified foods and supplements offer solutions. Understanding B12's importance and taking action can boost energy, metabolism, and well-being. Regular monitoring, a balanced diet, and appropriate supplementation are key strategies to prevent deficiency and maintain optimal health.

Subject: What Cellular Mitochondria Does in the Body

If you want to stay healthy, it's important that you know what cellular mitochondria does in the body. Mitochondria are organelles found in the cytoplasm of cells. They are responsible for producing energy for the cell. Without them, the cell would not be able to function properly. We will discuss the role of mitochondria in the body, and how they impact our health.

What are mitochondria and what do they do in the body

Mitochondria are organelles that play an important role in the energy metabolism of cells. Most of the oxygen we breathe is used by mitochondria to convert glucose from the food we eat into ATP, the energy molecule used by our cells. Therefore, mitochondria are often referred to as the "powerhouses" of the cell. In addition to producing ATP, mitochondria also have other important functions, such as regulating cell growth and death, as well as calcium homeostasis. Mitochondria are unique in that they have their own DNA separate from the DNA in the cell nucleus. This mitochondrial DNA is passed down from mother to child, which is why defects in mitochondrial function can lead to diseases that are inherited in a maternal lineage. Although most of our cells contain only a single nucleus, they may contain hundreds or even thousands of mitochondria. This allows them to produce enough ATP to meet the energy needs of the cell.

How mitochondrial dysfunction can lead to health problems

Mitochondria are integral to many essential physiological processes in the body. Not only do they produce energy for cells, but they also play a key role in maintaining cellular structures and initiating cell division. Therefore, any disruption of normal mitochondrial function can have far-reaching consequences for overall health and well-being. Maladaptive responses to environmental stressors, such as chemical exposure or radiation, are among the most common causes of mitochondrial dysfunction. These stressors result in damage to mitochondrial DNA and can cause problems with cell division and abnormal growth patterns, which can lead to a range of disorders and chronic diseases. For example, mitochondrial dysfunction has been linked to conditions like Alzheimer's disease and type 2 diabetes, as well as cardiovascular disease and cancer. Therefore, it is important to understand the role that mitochondria play in maintaining healthy functioning bodies and take proactive steps to prevent or reverse damage from maladaptive responses to environmental stressors.

Mitochondria and Longevity

Mitochondria are specialized organelles found within our cells that perform many critical functions, including generating energy to support cellular processes and maintaining healthy cell function. These organelles are the site of many important chemical reactions, often referred to as oxidative phosphorylation or metabolism. Studies have shown that Proper functioning of these organelles is essential for healthy aging, and may be a key factor in determining how long we live. By promoting mitochondria health and making lifestyle changes that help to promote healthy mitochondria, we can take an important step towards optimizing our longevity potential. This includes eating a nutrient-rich diet with a focus on foods high in antioxidants, managing stress levels through regular exercise and relaxation techniques, and avoiding environmental toxins that can damage mitochondria health. Through such strategies, we can give ourselves the best chance at living a long, full life.

Ways to protect your mitochondria and keep them healthy with PQQ

PQQ, or pyrroloquinoline quinone, is an important molecule for the functioning of mitochondria in the human body. This compound plays a crucial role in adenosine triphosphate (ATP) synthesis, the fundamental energy currency of biological systems. By driving cellular processes that release energy for metabolic use, PQQ plays a key role in maintaining mitochondrial health and efficiency. Additionally, PQQ has been shown to exhibit powerful antioxidant properties, which help to mitigate the effects of oxidative stress on mitochondria and other critical cells in the body. Overall, PQQ is an essential component of healthy mitochondrial function and a crucial nutrient for energy production and overall metabolic health.

D-ribose, the Mitochondria, and Energy

D-ribose is a naturally occurring sugar that plays an important role in cellular metabolism and energy production. This nutrient is especially important for cells that rely on a lot of energy, such as those found in the heart and muscles. D-ribose helps these cells to generate adenosine triphosphate, or ATP, which is the main energy currency used by cells to drive chemical reactions. Additionally, research has suggested that d-ribose can help to improve physical endurance and reduce the pain and stiffness associated with exercise, making it an important part of a healthy, active lifestyle.

Also, D-ribose is a simple sugar that plays an important role in the structure and function of mitochondria, the powerhouses of the cell. In addition to supplying energy to the cells, mitochondria also help to regulate cell growth and death. D-ribose is essential for the proper function of mitochondria, and it plays a key role in energy production. Studies have shown that D-ribose can help to improve mitochondrial function and reduce fatigue. In addition, D-ribose supplements have been shown to improve exercise performance and increase energy levels. These effects are likely due to the ability of D-ribose to help the body produce more ATP, the energy currency of the cell. For these reasons, D-ribose is an important nutrient for maintaining healthy mitochondria and supporting cellular energy production.

Another important nutrient for the mitochondria is CoQ10

The process of producing energy is called oxidative phosphorylation, and it involves the transfer of electrons from nutrients to oxygen. This reaction creates a proton gradient across the mitochondrial membrane, which is used to generate ATP, the energy currency of the cell. Coenzyme Q10 (CoQ10) is an important component of this process. It acts as an electron carrier, shuttling electrons between enzymes in the respiratory chain. It also helps to maintain the proton gradient, allowing the mitochondria to continue generating ATP. Without CoQ10, oxidative phosphorylation would grind to a halt, and cells would quickly run out of energy. Consequently, CoQ10 plays a vital role in energy production and cellular metabolism.

The bottom line is that both D-ribose and CoQ10 are important nutrients the body needs to maintain optimal energy levels. If you’re feeling run down, low on energy, or just generally not your best, consider taking a supplement containing these two nutrients. You may be surprised at how much better you feel once you start including them in your diet. What’s stopping you from giving them a try?

Subject: Did You Know That Folic Acid Can Help Prevent Birth Defects

There is continuing good press for folic acid in several aspects of human health, but the foremost health issue it addresses is a human reproduction. The popular belief that folic acid removes serious birth defects is supported by incontrovertible scientific facts. If a woman plans on getting pregnant, eating foods rich in folic acid is among other things that have to take priority.

Folate is an indispensable component of life in that it is directly connected to DNA and RNA processes, most notably in inhibiting changes to DNA. Folate deficiency results in the limited production of cells such as erythrocytes, also called red blood cells, bringing about abnormalities of cells in the body.

The fact that folate sustains the enhanced rate of cell division promotes the correct developments of body tissues and organs during pregnancy, significantly reducing the number of reported congenital malformations. Folate stabilizes DNA synthesis in red blood cells, hence the prevalent opinion that it is a must-have prior to conception. The employment of red blood cells is important to the first half of pregnancy as this time covers the central nervous system including the brain and spinal cord in the fetal development, leading to a drop in folate levels before and during this stage.

If you are planning or currently pregnant, supplementing folic acid is a must, consider taking a prenatal multiple vitamin that has folic acid added!

Subject: What Are Glycosaminoglycans (GAGs) And What Herbs Contain Them?

Glycosaminoglycans refers to a linear unbranched polysacharide chain molecule composed of disaccharides repeats with a high negative charge due to the presence of Uronic acid components and sulfate esters with some hydoxyl (OH) groups as part of its structural components. They have varying molecular size and sulfation depending on the tissue they are located on and their state. They function to attract cations and maintain the hydration of the extracellular membrane (E.C.M).

Glycoaminoglycans are classified into different groups based on different categories which include; glycosidic linkages in their structure, type of the sugar moiety, sulphate groups numbers and the location of the sulfate groups. Based on this various classification categories six major groups of GAGs exists, namely; heparin, hyaluronan, dermatan sulfate, heparin sulfate, chondroitin sulfate, and keratan sulfate.

GAGs have a high solvation degree and and are as well highly viscous. This is beneficial to the body in that it helps to cushion and lubricate various connective tissues and body joints respectively. It therefore protects an individual from joint pains due to poor lubrication of the joints causing the bone to slide over each other. They also form the building blocks of proteoglycans which are the major building blocks of the extracellular matrix. Due to this property they are vital in determining the cellular activities such as cell division because the cell division machinery has to attach itself to the extracellular matrix before the division process is initiated. Some body tissues such as the nerve cells and the muscle cells require continuous cell division to replace worn out cells for the normal functioning. This means that structural deformities in the extracellular matrix will hinder the division process to occur and is most likely to lead to some neurodegenerative complexions.

Recent studies have linked GAGs to play a role in the cell biology of cancer.They have been established as the key macromolecules affecting cell properties and functions through interaction with key growth factors or by acting directly as receptor molecules. Through this it has been findings they play a vital role in the cell signaling process thus playing a role in the cancer disease progression.Heparin and heparin sulfate have been indicated through studies to have anti-tumor effects by preventing the process of angiogenesis which is the first step in cancer metastasis.Some have been associated with anti-coagulant properties.

Therefore GAGs are important molecules which play a vital role in protection against various forms of cancers. GAGs aremostly obtained from animal sources. The animal sources include shark fish and ray skeletons. Plants are also sources of GAGs, however their digestion by the human system is not possible. Seaweed is one herb that is rich in GAGs. However as earlier explain the digestion of the sea weed by the animal digestive system is quite a challenge. It is therefore recommended that we eat foods rich in proteins, and carbohydrates which can be used to synthesize GAGs in the body.

In summary, GAGs are heteropolymers which acts as the building blocks of the extracellular matrix in animals. The body has the ability to synthesize GAGs naturally hence nutritional supplement is required for the body to obtain key components necessary for the synthesis.

Subject: How Does Artemisinin Boost Your Health?

What is Artemisinin?

Artemisinin also known as Ching hao su is a herbal medicine that is extracted from wormwood herb. Asians have been using this leaf for many years to treat simple ailment such as parasitic infections and cold. However, it has recently become very useful for its effect on malaria. The herb has been used to treat parasitic infections, mainly worms and flukes that strain our body not only on feeding them but also in excreting their waste & by-products. Malaria is caused by such a parasite and artemisinin has proved to be effective solution.

Artemisinin and Malaria

The plant contains a chemical known as Endoperoxide Bridge that reacts with iron to form free radical which is unwelcomed in our body. Nevertheless, malaria parasites have high level of iron that reacts with artemisinin to form free radicals that kill off the parasite. This has become the best cure for malaria since the parasites that cause it have developed mutant to many cures and they are not resistant to the endoperoxide.

What are Other Benefits of Artemisinin?

For other application is in the fight against cancer. Different cancers such as colon cancer and leukemia that involve iron rich cells can be destroyed by artemisinin by the same mechanism that kills off malaria parasites. Cancer cells are known to accumulate iron because they need it in cell division process. However, if you’re using artemisinin for treatment of cancer cells, it is important not to eat antioxidant containing supplements or foods because this drug work by creating free radicals that destroy cancer cells, antioxidant activity is known to counter these free radicals.

If you are suffering from intestinal parasites, then taking a gram or two each day will keep them off. This supplement is also effective when you are dealing with cough, cold and other general conditions but is more effective in the ones that cause fever. The Chinese have been using it as a form of “cure all” when specific remedies fail.

Subject: What Makes Beta Carotene The Safer Vitamin A.

What are the Importance of Vitamin A

The most important type of vitamin A, is in no doubt beta carotene, a type of carotenoid. The main source of beta carotene is carrots. Carotenoids act as anti-oxidants and anti-inflamatory nutrients. Beta carotene is considered a safe vitamin A source because its sources are vegetables, for instance carrots, meaning that it is low in fat content.

Subject: Can Resveratrol Help Fight DNA Damage?

How resveratrol helps in fighting DNA damage

Resveratrol is a naturally occurring antioxidant produced by plants to protect them against attacks by predators such insects, bacteria or fungi. This antioxidant which has been the subject of several scientific studies is usually found in large quantities in grape skin or red wine. Although the body can function without it which means that you can not be termed as deficient of this nutrient, the compound is known to have immense health benefits. Scientists claim that human beings have not yet fully discovered the real benefits that can be derived from this antioxidant.

Scientists have demonstrated that Resveratrol is quite effective in fighting DNA damage which is responsible for aging as well as disorders that are associated with aging including Parkinson's and Alzheimer's disease. Cell degeneration in vital organs is usually linked to certain factors. An important factor that causes cell loss is the presence of reactive oxygen species (ROS) by mitochondria in the cell which is responsible for cell death and DNA damage. Preventing mitochondria turnover and bio-genesis guards against oxidative mitochondria thus promoting healthy aging.

Cell degeneration has been effectively controlled by using a diet that is low in calories so as to increase mitochondria biogenesis. Adding resveratrol to your diet has the same effect since this antioxidant mimics dietary restriction thus delaying diseases related to aging.

The compound has been known to stall the aging process by acting as sirtuin activator. It is also responsible for various effects on fat cells which alter fat mass by acting on cell viability and adipogenesis in mature preadipocytes. Laboratory tests have demonstrated that this compound stimulates bio-genesis which helps in delivering immense health-related benefits in mice. The antioxidant fights off cancer which occurs when there is cell damage during cell division. The compound stops cell division in order to allow enzymes repair damaged genes .It also prevents carcinogenic metabolism, a common cause of DNA damage.

Subject: How DoesTurmeric Help Improve Your Health?

Turmeric - Curcumin

This is a perennial herbaceous plant which belongs to the ginger family making it an important plant because of its active ingredient, curcumin and other properties which makes it avery useful plant in terms of health when used. The rhizomes of turmericare gathered annually for preparation of various health products or foods or taken on its own as they are known to have greater concentrations of curcumin and other substances which are essential for good health. When turmeric is taken, it improves one's health in the following ways:

Weight loss; for those people who are overweight and obese, they always face a challenge on how they can get rid of some extra weight as it is associated with negative health implications and on the other hand fats such as belly fat decrease one's self esteem. Turmeric is one of the herbs that if mixed with food will increase the rate of metabolism which will consequently help in fat loss which will ultimately have an effect on the weight. Thereforemanageable weight will always ensure that one is not at risk of developing cardiovascular heart diseases and other lifestyle diseases which will ultimately promote good health.

Cancer and turmeric; cancer is one of the killer diseases which was very common in developed countries but nowadays it is very rampant even in developing countries. By taking turmeric, the active ingredients in it will help in stopping and preventing the development of cancer more especially prostate cancer which affects men. This herb interferes with the abnormal cell division of the cells hence leading to a stop or prevention of cancer progression thus health improvement. It is important to note that turmeric is also very effective in preventing other types of cancers for example breast cancer from spreading to other parts of the body such as the lungs. The effectiveness of turmeric in fighting cancer can be increased by mixing it with cauliflower flower.

Detoxification; turmeric is rich antimicrobial properties, antiseptic properties which make it a very useful plant when it comes to cleansing of the body. The body is usually bombarded with a lot of chemicals and toxins from the environment and what is eaten hence need to cleanse it. This can be achieved by taking turmeric on its own or mixing it with other foods and taking it two to three times a day for a period of about one month. This will go along way in detoxifying the body more especially the liver which will make it more healthy hence work better as it is one of the largest organ in the body.

Fighting inflammation; this is one of the common symptom of very many ailments and by taking turmeric, it will be able to fight inflammation resulting in improved and good health. It has also been associated with the reduction or clearing of symptoms of arthritis (rheumatoid arthritis and osteoarthritis). This will improvemotion of the patient which willfinally have an impact on performance of the patient thus have a positive impact on the health of those with these conditions.

Turmeric can also be used as a natural disinfectant for example when burns and cuts occur at home, it can be applied thus hastening the healing process.

As you can see, turmeric with curcumin has a wide range of uses, you too should have this wonderful herb on hand in case of emergencies.

Subject: What Is the Life Span Of Human Cells And How Do Antioxidants Help?

The human body is composed of many different cells. These cells have varying functions as well as life span. The human cells, in general, are very complex. Some cells may last only within a day while others may be for life. Like for example, one blood component known as neutrophil lasts only within 24 hours. On the other hand, another blood component which is red blood cell has a life span of 120 days. One human cell which lasts for a lifetime is the stem cell. Stem cells are undifferentiated cells which are the source of blood cells. They supply the body throughout life both with red and white blood cells. Here is a brief outline of some cells of the human body with their corresponding life spans.

1. Granulocytes such as eosinophils, basophils and neutrophils – half day to 3 days

2. Stomach and colon lining cells – 2 to 4 days

3. Sperm cells – 2 to 3 days

4. Epithelial cells of the small intestines – 5 to 7 days

5. Platelets – 10 days

6. Skin epidermal cells – 14 to 28 days

7. Lymphocytes, macrophages and endothelial cells – 2 months to a year, but may vary

8. Pancreatic cells – a year or more

9. Bone cells – 25 to 30 years

As shown above, these human cells have an expected time of death. However, if the body is exposed to harmful toxins, their life span significantly decreases. As we know for a fact, the body undergoes many biological reactions almost every second. The reaction is called oxidation process which is essential to the body. However, such reaction has harmful by – products in the form of free radicals. Free radicals can cause the body significant damage. Free radicals can cause destruction and death of the healthy cells of the body and also affect the body’s cellular division. This kind of chemicals can potentially tamper DNA replication during cell division. Once cellular division is tampered, abnormal growths would likely happen. Aside from the naturally occurring free radicals, external stressors can also cause damage to the cells of the body. Some of these include pollutants, harmful chemicals and irritants. These harmful chemicals can potentially lead to the development of certain disease conditions such as heart diseases, stroke and cancer.

Fortunately, there are many antioxidants which can greatly help in the prevention of free radical damage by protecting the cells of the body. Antioxidants are molecules which can effectively prevent the oxidation of other molecules. There are many natural antioxidants found among plants and animals. Some common antioxidants are glutathione, vitamin C and vitamin E. Other nutrients which have antioxidative property include beta – carotene, lutein, lycopene, vitamin A and selenium. Fruits and vegetables are great sources of antioxidants. Nuts, grains, meat, poultry products and fish are also good sources of such cell – protecting chemicals. In addition, dietary supplements of antioxidants are also widely available in the market. However, health experts highly suggest that before supplementation of antioxidants, medical evaluation must be done first to be completely safe.

Subject: Vitamins and Herbs

The whole human body is made up of cells that contain their own genetic material. In a healthy body, these cells divide at a controlled rate, growing and repairing damaged tissues and replacing dying cells. This predetermined rate of cell division is what keeps our bodies healthy. If cells keep multiplying when new ones are not necessary, a mass of tissue, often known as a tumor, is formed. This tumor can be either benign or malignant.

Benign tumors are not cancerous and can occur anywhere in the body. Benign tumors do not cause a threat to health, do not metastasize, and do not grow back if removed. Malignant tumors are cancerous and are usually serious. Often times, they can be life-threatening. Malignant tumors grow uncontrollably, interfere with normal metabolic and organ functioning, and have the ability to metastasize and invade other tissues. If a portion of a cell’s DNA is damaged, the cell can become abnormal. When an abnormal cell divides, it forms new cells that are a photocopy of the damaged genetic material. This ongoing process occurs constantly within our bodies. The majority of the time our bodies have the ability to destroy these abnormal cells and maintain a sort of cellular equilibrium. If a crucial part of the DNA is destroyed and the abnormal cells cannot be controlled any longer, cancer forms. All cancer cells have two things in common: growing uncontrollably and having the ability to metastasize. The immune system does not recognize cancer cells as dangerous or foreign.

Although the exact cause for the cell damage that initiates the cancer process is unknown (theoretically free radical damage causes DNA damage), the chain of events that leads to cancer is very complex, and each individual body reacts differently. It is a combination of genetic, behavioral, environmental, and lifestyle factors that are thought to be involved in turning normal cells into abnormal cells, and abnormal cells into cancer.

There are also factors that are believed to slow the process, while other factors can speed up the process. Possible contributors to the development and growth of cancer can be divided into three categories: external, internal, and lifestyle. External factors include unhealthy workplace environments and exposure to air and water pollution, chemicals, pesticides, and herbicides. Included in the internal factors include both genetics and infections. Lifestyle factors are those we personally can most readily control, such as diet, smoking, drinking, and sun exposure. External and lifestyle factors account for 80 percent of cancer deaths in the United States.

Just as each of us looks different, each of our bodies has its own unique composition. Some of us may react adversely to what some of us react well to. This is why some treatments prove to be successful for some, but not for others. This is why dietary wellness and prevention is so important. If we can keep our bodies healthy and avoid known cancer-causing agents, we have a good defense against cancer in the first place.

The following nutrients and supplements are designed for persons who have been diagnosed with cancer, as well as for those who wish to enhance their chances of avoiding the disease: coenzyme Q10, colostrum, DMG, garlic, IP6, melatonin, MSM, proteolytic enzymes, selenium, 7-keto DHEA, shark cartilage, SOD, vitamin A, shiitake extract, acidophilus, chromium picolinate, flaxseed oil, grape seed extract, kelp, l-carnitine, multienzyme complex, a multi-mineral complex, multivitamin complex, NAC, raw glandular complex, taurine, and vitamin B complex. Additionally, the following herbs may be beneficial: astragalus, birch, burdock root, cat’s claw, chaparral, chuchuhuasi, cranberry, dandelion, Echinacea, fennel, green tea, licorice root, macela, milk thistle, parsley, pau d’arco, red clover, suma, cardamom, cayenne, ginger, rosemary, sage, thyme, turmeric, ragwort, wood sage, curcumin, essiac, noni, olive leaf extract, rosemary, and boswellia.

All of the above listed herbs and vitamins can help restore the body to good nutrition and help boost the immune system so the body can find and fight back against cancer. Natural vitamins and herbs are available at your local or internet health food store. When purchasing supplements, look for name brand vitamins like Solaray and Source Naturals to ensure you receive quality and you get what you pay for.

Subject: Noni Fruit Extract

Tahitian Noni juice can promote a healthy body in many ways. These Noni benefits are conferred by the phytochemicals contained within the fruit pulp, but before discussing the benefits of Noni let's first have a look at what it actually is.

Morinda citrifolia is also known as the Indian or beach mulberry tree, and is a member of Rubiaceae family. Although it originated in Southeast Asia, it has spread all the way to French Polynesia and the Dominican Republic. It is mainly cultivated in Tahiti for its fruit, known as cheese fruit or Noni fruit.

Although it is a staple food in some areas of the Pacific, it has a pungent smell and a bitter taste, and often eaten either raw or cooked only in times of famine. However, the fruit is particularly rich in phytonutrients, and many people swear by the Noni benefits it to maintain a glowing healthy body, free from disease and many of the health problems from which most people suffer.

The strange thing about it is the taste: you would not drink Tahitian Noni juice by choice, nor eat the fruit, so how were these Noni health benefits discovered? Hunger likely explains it: those forced to eat it through hunger were likely the lucky ones, who actually ate a nutritional diet even though they were eating a fruit normally eaten only in times of famine.

Among the conditions that Noni fruit is believed to protect you from are cardiovascular disease, high cholesterol levels, asthma, cholesterol, strokes, migraines, a weak immune system, arthritis and some cancers. Many of these conditions should give you a clue as to the nature of the phytochemicals contained within the fruit, since most of them involve free radical attack and immune system response.

Prior to examining thee diseases and conditions in detail, let's have a look at the chemicals the fruit has been established to contain. It is rich in dietary fiber, offering 100% of the Dietary Reference Intakes of the Institute of Medicine for each 100g serving, and also contains enough carbohydrate to meet 55% of you DTI needs. However, that is just the start.

The Noni pulp powder contains ten times the DRI of Vitamin C, and large quantities of Vitamin B3 niacin), potassium and iron. The Tahitian Noni juice itself contains few nutrients, and only the Vitamin C is retained to any useful level. It is therefore the pulp powder that offers the major nutritional benefit. In fact, because it has to be pasteurized at high temperature to meet regulations the for liquid product, Noni juice loses most of its nutritional content, and even the 31% Vitamin C content is surprising since that too is destroyed at high temperatures.

It is the high phytochemical content of Noni powder that renders it such an important supplement, and a scan down the following components will give you an idea of how the fruit got its reputation. The known Noni benefits are obtained from:

Lignans: these are phytoestrogens that have been reported to offer a reduced risk of ovarian and breast cancers, osteoporosis and also cardiovascular disease. They possess antioxidant properties and although reports as to their effectiveness are varied, they appear to have beneficial health effects.

Flavanoids: These are phenolics, including asperulodisic acid and rutin. The former is believed to be effective against certain cancers, while rutin, also contained in buckwheat, is a strong antioxidant that strengthens capillaries, and also helps to prevent atherosclerosis and heart disease.

Catechin and epicatechin: strong antioxidants that help prevent heart disease, strokes, diabetes and cancers. It also protects your skin against the harmful effects of the ultra-violet component of the sun's rays. Catechin is a form of flavanoid, and one of the more powerful of the antioxidants needed to destroy the free radicals that would otherwise ravage your body through the destruction of your body cells.

B-Sitosterol: a plant sterol that is believed to reduce the cholesterol in your blood, but still requires scientific proof, even though there is plenty of evidence to support its effect. Plant sterols are the basis of the cholesterol-lowering yoghurt drinks that you can but in your local supermarket.

This list is not exclusive, and there are several other phytochemicals found in Noni pulp powder that are believed to confer significant health benefits, but that are still seeking scientific support. The fact that such support has yet to be provided is not a reason to doubt their effectiveness, although the above benefits are sufficient to justify the reputation of this nutritional supplement that few have heard about.

There have been only around 110 reports on Noni research since the 1950s, so it is not surprising that the scientific proof is weak, although of these around 100 have appeared since the year 2000. Don't forget that there was no proof for the effectiveness of penicillin until it was discovered!

Even the biochemistry of the components of Tahitian Noni juice, such as the polysaccharides not mentioned in the above list, is in the early stages of research, and an increasing number of traditional remedies are being found to have a valid scientific and medical basis. These polysaccharides are a form of dietary fiber with probiotic properties that can be fermented by bacteria in the gut to form short chain fatty acids that possess many beneficial health properties.

Take the heterocyclic iridoids, for example. These are unknown to most people, yet they are found in many plants that have extensive medicinal properties, and might be responsible for many of them. They appear to possess anti-inflammatory, antiviral and antispasmodic properties, and support the cardiovascular system, the immune system and help to maintain a healthy blood sugar level. These are also contained in Noni pulp powder.

Another component of Noni fruit that most people have not heard of is damnacanthal. This inhibits certain tyrosine kinesis that basically have a controlling effect on the division of body cells. They particularly inhibit the Ras genes, responsible for some cancers due to uncontrolled cell division. Damnacanthal can prevent Ras genes from causing these cancers.

There are many more benefits that Tahitian Noni juice, or particularly the powdered Noni pulp, can confer, and it is recommended that it be taken as a supplement by anybody needing a general health tonic since it possesses such a wide variety of beneficial properties. The Noni benefits which those that use it enjoy area available to everyone, even though it is one of the lesser known of the beneficial health supplements.

Subject: Glycine

The non-essential amino acid glycine is needed to generate muscle tissue and also for the conversion of blood glucose into energy. It is referred to as being ‘non-essential’ because the body can manufacture its own glycine, and is therefore not an essential component of your diet. Other uses to which glycine is put by the body includes the maintenance of a healthy nervous system, and is necessary for the proper functioning of the digestive system.

Amino acids play three essential roles in the human body:

1. They are the building blocks of proteins: proteins comprise about half of the dry weight of the majority of your body cells, and without them there would be no life. They are produced using monomers known as amino acids, and there are about 20 different amino acids used to make the vast variety of proteins that make up the human body. Proteins are needed to form enzymes, the catalysts that permit the majority of chemical reactions within our bodies, and also genes, the building blocks of DNA.

2. More relevant here, amino acids play an important role in the production of ATP (adenosine triphosphate) from ADP (adenosine diphosphate) by phosphorylation with creatine phosphate. The more creatine phosphate available, the more ATP can be produced. Since ATP is the molecule responsible for the generation of energy, then the more ATP available the more energy is generated. Although creatine is available from many food sources, it is destroyed by cooking, and over half of what you use is made from the three amino acids, glycine, arginine and methionine. The energy produced in this way is very short-lived, and last only a few seconds - more on that later.

3. Glycine is heavily involved in the production of collagen, which is the substance that maintains the flexibility of your skin and other connective tissues while still maintaining their strength and firmness. Without glycine your skin would become slack due to the degrading effect of sunlight, free radicals and oxidation.

The non essential amino acid, glycine, is believed to offer other benefits to the human body, but it is the second of those above, the production of ATP, which interests us here. ATP is an extremely important nanomolecule, second in importance to the body only to DNA, and possibly also RNA since the two are linked. RNA makes copies of your DNA structure for use in cell division and growth.

When a cell expends energy for whatever reason, such as when I am typing this, or when your heart beats, or even when your liver synthesizes a protein, one of the phosphate groups is removed from the adenosine triphosphate molecule, and converts it to adenosine diphosphate (ADP). The ATP is then said to be 'spent', just as your energy is spent when you are tired and can exercise no more.

The ADP is then immediately reconverted to ATP in the mitochondria, a part of every cell in your body. A cell can contain hundreds, or even thousands, of mitochondria, the number depending upon that particular cell's need for energy. Hence, cells in your muscles, or in your liver where most of the body's chemistry takes place, contain thousands of mitochondria whereas those in your scalp contain a lot less. Once changed to ATP, a phosphate is again lost when energy is expended, and so the cycle continues.

Glucose is needed allow the ADP to be converted to ATP, hence the need for sugars, or the carbohydrates from which they are manufactured in your body. Each cell can contain up to a billion molecules of ATP, although the couch potatoes among you probably have a lot less! Your store of ATP molecules last about 2 to 5 seconds before being changed to ADP although more rapidly for athletes that expend a lot of energy. Then the energy stored in the form of glycogen in the liver kicks in for another 4 - 6 seconds.

Additionally, you cannot expend more energy that the (eventual) sugars that you take in your diet, which can be in the form of ordinary 'sugar' (sucrose), fruit (fructose), glucose, carbohydrates that are metabolized into sugars, or any other member of the sugar family (e.g. lactose, maltose, etc.).

Glycine is one of what are called glucogenic amino acids, which refers to their ability to provide glucose to the blood. Because it helps to maintain proper blood glucose levels, it is often prescribed for conditions that are caused by low glucose levels, such as hypoglycemia that shows symptoms of fatigue and tiredness, and also anemia and what is known as CFS (chronic fatigue syndrome).

The one activity of the human body, in fact that of any mammal, for which ATP is essential, is the heartbeat. Without that no mammal could survive, or any other creature that relies on a circulation system for life. The only reason you heart has to beat is to pump your blood around your body, and it is your blood that contains the oxygen and nutrients needed to sustain life. Your cardiovascular health relies on lots of ATP being available to power each and every heartbeat.

Analysis of the heart during the final stages of heart failure has revealed that there is a general decrease in the myocardial arginine: glycine amidinotraferase (AGAT) gene expression, which is indicative of the necessity of this enzyme for proper heart function. The enzyme is responsible for the first stage in the biosynthesis of creatine from glycine.

Creatine is well known to athletes, and while it is available naturally from some food sources, it can be destroyed during cooking, and at least 50% of the creatine needed by the body is produced in the liver, pancreas and kidneys. It is creatine phosphate that is broken down into creatine and phosphate, the latter of which is used by the mitochondria to regenerate ATP from ADP.

The study carried out on the reduced AGAT levels found in heart failure patients indicates the importance of glycine to heart health. Without a good supply of glycine, there will insufficient creatine produced biochemically to generate the phosphate needed to for the ATP to produce the energy required to keep the heart pumping with the required strength. The energy provided by the mitochondria is used locally by the cells in which it is produced, and within a few seconds of that production. As explained earlier, ATP stores are used up within 2 - 5 seconds, and glycogen stores within another 4 - 6 seconds.

That is why sprinters cannot keep running at maximum speed for more than around 10 seconds or so, because the immediate availability of glycine, and hence creatine, are insufficient to last longer than that. That is one reason why they have to finish those 100 meters as fast as possible, because otherwise they would run out of energy. Other than trying to win, of course!

However, when it comes to the heart, ATP stores are essential, and the cells in your heart require a constant supply of ATP from creatine, which itself depends upon your intake or biosynthesis of glycine. Since dietary sources are insufficient to meet all your needs, and destroyed by cooking, a glycine supplement is the only way to ensure a sufficient intake. You cannot undernourish your heart and remain healthy.

ATP biosynthesis is essential if that of glycine theoretically is not, but the fact that 50% of your glycine requirement has to be produced by your body and the other 50% is sensitive to heat during cooking, a supplement of glycine could be essential to many people.

Subject: Folic Acid

Folic acid is an important vitamin to the developing fetus in that it aids cell development, particularly those cells involved in the development of the baby's spine. A deficiency can result in neural tube defects, in which the neural tube, down through which the central nervous system passes, fails to close properly.

However, let's first discuss the substance itself so that its function in that process can be more easily understood. Neither should we ignore the other benefits that folic acid gives us, or the problems we can have in the event of a deficiency.

Folic acid is a form of Vitamin B9, sometimes referred to as Vitamin M. Its anionic form is known as folate, which is the form in which it is frequently offered in supplements. Incidentally, it gets its name from the Latin for leaf, so is from the same root as foliage. It is water soluble, and like Vitamin C can be leached through the body if not immediately used.

It is available naturally from leafy and green vegetables such as lettuce, broccoli, spinach and peas, but is also available in fortified breakfast cereals, sunflower seeds and some fruits. You would not normally suffer a deficiency, but if you are taking anticonvulsants, have liver problems or undergoing kidney dialysis, then you might need a supplement. Pregnancy, of course, is the important case in which a supplement should be taken, although, surprisingly, many mothers-to-be are unaware of this.

New body cells need folate for their production, particularly when they are dividing and growing rapidly such as during pregnancy and in infancy. The formation of DNA depends on many chemical entities, among them four nitrogenous bases, of which three, thymine and the two purine bases, adenine and guanine, depend on folate for their synthesis. If the growing fetus is lacking folate then DNA synthesis will be hindered. This retards cell division and growth.

Among the conditions this can cause are a form of anemia known as megaloblastic anemia, and neural tube deficiencies, where the sheath that surrounds the main nerve canal up the spine fails to close properly. The best known of such neural tube defects is spina bifida, though any condition caused by a lack of cell division can also occur. Anemia can be contracted by both adults and children, since production of red blood cells takes place constantly throughout your lifetime. These are the reasons why folic acid or folate is used in breakfast cereals.

The biochemistry is fairly simple to understand, and is important because it explains the importance of two other B vitamins, B3 and B12, in DNA synthesis. The initial stages are a six step reaction that forms methyl tetrahydrofolate from folate, starting with the reduction of folate to dihydrofolate, and then a further reduction to the tetrahydrofolate (THF). Vitamin B3 (in the form of nicotinamide adenine dinucleotide phosphate) is an essential cofactor for these reductions. Vitamin B12 is necessary as an acceptor for the methyl-THF so that it can continue along the biochemical pathway - now that is too complex to discuss here!

However, the inference you can rightly draw from this is that a deficiency of Vitamin B12 can cause what is known as a 'methyl trap', whereby the methy-THF cannot be used, and so a deficiency in Vitamin B12 can lead to the same symptoms as a folic acid or folate deficiency.

The implications of that are that vitamin B12 is also an essential component of a pregnant woman's diet. The problem here is that this vitamin is available only from animal sources, including dairy products. Its presence in vegetable organisms such as certain algae and fungi has been proposed, but it is believed that the cobalamin (chemical term for the vitamin) from these sources is not bioavailable to humans.

Vegans, therefore, who do not eat dairy products, will need a Vitamin B12 supplement in addition to folic acid or folate, particularly when they are pregnant and with young growing children. In this respect, a vegan diet is unsuitable for young children until their rapid growth period has stabilized.

For those of you wondering why the biochemistry above was discussed: that is your answer. Such discussions can frequently explain why certain supplements are necessary, or certain diets should be reconsidered under particular circumstances. Such things are easier to understand and accept when the logic behind them are explained. A folic acid supplement taken from the onset of pregnancy up to 12 weeks at least, and also a Vitamin B12 supplement in the case of those with a low meat intake, should prevent neural tube defects such as spina bifida.

A daily supplement of 0.4 mg should be sufficient, along with a diet rich in green vegetables, fortified cereals and breads and oranges. Your greens are best steamed since prolonged boiling destroys folic acid - as it destroys Vitamin C. One source of folic acid that you might read about is liver, and its additional iron content might lead you to believe this to be a good component of your diet when pregnant. However, although normally a very nutritious food, liver should be avoided during pregnancy due to its high Vitamin A content. This can be harmful to your baby.

Finally, there are some circumstances under which the dose during pregnancy should be greater. If you have previously had a child with a neural tube defect, or have an NTD yourself (or your partner), if you are diabetic, if you have celiac disease (a gluten allergy) or are taking anti-epileptic medication, you should increase your dose to 5 mg (milligrams) for which you will likely need a prescription from your physician.

NTD is rare, so don't over-worry much about it, but take the above precautions to put your mind at rest since pregnancy is not a time during which you should be nervous but to enjoy. That will pass on to your growing baby, which will then itself be happy.

Subject: Antioxidants For The Body

Eating the fruits and vegetables that naturally contain antioxidants is the best way to get them into your system. Mixing them into a well-balanced and healthy diet is the best method of all. This way you reap the benefits of all of the antioxidants in a natural combination.

The benefit of dietary antioxidants is that they slow the chemical process of oxidation. This oxidation is what causes narrowing of the arteries and heart-related health problems due to cholesterol deposits. Eating a regular variety of herbs, vegetables and fruits that contain antioxidants is the best way to maintain good health. Some foods that contain antioxidants include:

* Tomatoes
* Garlic
* Onions
* Rosemary
* Grapes
* Pomegranates

Antioxidant supplements are available, lab testing have shown that they are just as effective as their natural counterparts. Natural foods contain ranges of antioxidants that work together synergistically. These combinations of antioxidants are much more effective.

More Benefits:

Antioxidants and other nutrients are needed by the body to protect against cell damage. They also may reduce the risks of certain forms of cancer.

It has been discovered that the mitochondria (cell power plants) are a major source of oxidant production. They are also a target for the damaging effects of the very oxidants that they produce. This is a major cause in the advancement of cellular aging, called apoptosis.

It is believed that in apoptosis, each cell has a fixed number of cell divisions that it is capable of. After the cell has used its allotted number of divisions, it ceases to function. Oxidative damage is also a contributing factor of DNA mutation, which causes further malfunction of the cells.

Most Common Antioxidants:

The following is a list of the most common antioxidants, what benefits they offer and where to find them:

*Beta-carotene keeps the skin healthy and promotes growth and development of bones. It also helps to prevent night blindness and fight infection. Beta-carotene is found in vegetables and fruits: carrots, cantaloupe, apricots, broccoli, peppers, tomatoes, spinach, sweet potatoes and pumpkin.

* Vitamin C destroys free radicals inside and outside cells. It helps in the healing of wounds, preventing bruising, formation of connective tissue, iron absorption and keeping gums healthy. Vitamin C is being studied for its beneficial effects in reducing cataracts, cancer and heart disease. Foods high in vitamin C include tomatoes, citrus fruits and juices, berries, mango, papaya, peppers, cabbage, spinach, broccoli and potatoes.

* Vitamin E acts as the essential fat protector in cell membranes and red blood cells. It reduces the risk of heart disease, cancer and other diseases associated with age. Vitamin E is found in peanut butter, nuts, seeds, vegetable oils, margarine, whole grains, wheat germ, salad dressings and avocado.

* Selenium helps the body maintain healthy hair and nails. It also enhances immunity and, along with Vitamin E, prevents cell damage. Vitamin E reduces the risk of cancers, especially prostate, lung and colorectal. The best sources of Selenium include brazil nuts, garlic, meat, eggs, poultry, seeds, seafood and whole grains. The amount of selenium found in plants depends on the soil content in which they are grown.

Antioxidants benefit the body by providing a layer of protection for the tissues and cells. They are the front line of the body's protection against free radicals. Free radicals are unstable by-products of oxygen that cause premature aging and degenerative diseases. They also come from environmental sources, such as pollution, UV rays and other toxins. Foods rich in antioxidants help to clean free radicals from the body. They also help to prevent various age-related diseases, cancers and heart disease.

Maintaining a healthy, nutritionally balanced body that has the ability to fight disease and infection is a prime way to live a long, disease free and happy life. Regular ingestion of antioxidant rich foods or supplements is the best method to achieve this.

Subject: Artemisinin For Better Health And Wellness

Artemisinin, also called Ching-hao-su is a herbal medicine extracted from the sweet wormwood herb, also known as the Artemisia annua. Asians have been using the leaf for centuries to cure simple ailments such as colds and parasitic infections, but it has recently become big business for its effect on malaria.

Sweet wormwood is predominantly a Chinese herb, used for over a thousand years for treatment of a large variety of conditions including malaria. It has also been used to treat wound and skin diseases, and has been recorded as far back as 200 BC as a component of Chinese prescriptions for specific illnesses.

Although the origins of sweet wormwood are in Asia however, it is now grown throughout the temperate regions of the world, and reaches its best in midsummer. Although best known today for its use in treating malaria, its medical uses include treating bronchitis, fevers and general feelings of malaise. It is primarily grown now for the supplement industry and as a non-prescriptive natural cure for malaria. It is a common and favorite herb for Chinese herbalists and sold both in the herbal form and as the extracted artemisinin.

Although there is a wide variation in the artemisinin content of sweet wormwood according to where it is grown, and under different agricultural conditions, it is the main active ingredient. Chemically, it is a sesquiterpene lactone containing an endoperoxide bridge that will be discussed later.

In order to attain the optimum yield of active artemisinin, the plant has to be grown in the right site for cultivation and fed with the correct fertilizers, the proper strain of the herb must be selected and the method of extracting the active chemicals is also critical. These are secrets that have been used for centuries by the Chinese herbalists who are masters of their craft and are now known to the west and being applied to scientific production of the extract.

There are benefits of artemisinin other than its effect on malaria, but that is the best known of its uses, so let’s have a look at that first. The herb has been used for a long time to treat parasitic infections, mainly flukes and worms that place great strains on the body having not only to feed these unwanted creatures, but also to excrete their waste and by-products. Malaria is caused by such a parasite, any one of four types in fact, and artemisinin appears to be just as effective on them.

The chemical contains what is known as an endoperoxide bridge that reacts with iron. The product of this reaction is a free radical, normally unwelcome in the body. However, malaria parasites contain high levels of iron, and the artemisinin reacts with that iron, forming free radicals that then go on to kill off the parasite. The free radicals that we take supplements to destroy, actually work for us in the destruction of the parasite that cause malaria. There is a silver lining in every cloud!

The reason that the medical world is so excited with this material is that malaria is second only to tuberculosis in its impact on world health. The problem is that the parasites that cause it have become largely resistant to the normal cures. They are not, however, resistant to the endoperoxide chemistry contained by artemisinin. It is now the major hope of world leaders in the fight to stop the inexorable increase in deaths due to malaria.

Now for the other applications. Another major use of the chemical is in the fight against cancer. Those cancers that involve iron rich cells can be disrupted by artemisinin by the same mechanism that kills off malaria bacteria. It is not only parasites that are susceptible to free radical action, but also human cells, and if these can be selectively destroyed, then it is a step forward towards a cure for cancer. Such a cure does not yet exist, but mechanisms such as the endoperoxide bridge provide a means of controlling at least some cancers, the best results being obtained with leukemia and colon cancer. That is not to say, however, that cures for these cancers are currently available since tests are still under way. However, it would do no harm to use sweet wormwood or the artemisinin extract as a supplement.

Cancer cells tend to accumulate iron because it is needed in the cell division process that cancer takes advantage of. However, if cancer cells could be persuaded to accumulate more surface iron, or were artificially exposed to it, then perhaps the endoperoxide mechanism would be more effective. Studies on this mechanism of controlling cancer are currently under way.

At a more mundane level, if you suffer from intestinal parasites, then one or two milligrams each day should see them off. It has also been effectively used to deal with colds, coughs and other general conditions, but most effectively against those that cause fever of one kind or another. It has been used in Chinese medicine as a form of ‘cure-all’ to be used when specific remedies failed. Its greatest current uses are, however, in cancer and especially malarial treatments.

You have to be careful with artemisinin since it can be toxic if taken in the wrong form. The least toxic, and most active, is the water soluble form known as artesunate. However, it lasts the least time in the body and has to get to work quickly. The oil soluble form, artemether, is the most toxic, but can cross from the blood to the brain. However, the parent form, artemisinin is the very safe itself, and can also cross the blood-brain barrier and while some tend to use a combination of the three, others prefer just the parent form.

If you take too high a dose you can suffer neurotoxicity which makes you wobble when you walk, and makes you impervious to certain levels of pain. However, such doses are next to impossible accidentally, and there have been very few reports of adverse effects in humans. It should not be used for at least a month after you have had radiation therapy because that tends to release iron that can be attacked to form free radicals. The recommended dose is 200 – 100 mg daily though the doses should be spread throughout the day. It should also never be taken within 2 hours of any other antioxidant such as vitamins A, C and E. Otherwise artemisinin can be safely used for better health and wellness in the way that the Chinese have been using it for centuries. Artemisinin is available at your local or internet vitamin store.

Subject: New Test for Early Cancer Detection

A new test for early cancer detection

Researchers out of Johns Hopkins University believe they may have found a new method of testing for cancerous growths that allows for much earlier detection. The new method of testing saliva and urine does not work for all cancers but would allow doctors to check for DNA abnormalities in these fluids. If these tests prove viable, they would allow for cancer detection years before symptoms appear.

Tests on patients suffering from cancers of the lung, voice box, mouth, throat and bladder showed 100 percent sensitivity to abnormal DNA particles. Researchers say that a mutation in the tumor guaranteed a detection in the bodily fluid.

The test works by detecting DNA strands that have been dumped by the tumor into the bloodstream and excreted by the body. These mutated DNA strands lead to dysfunctional cell division and give rise to tumor development and growth. In order to further test their theory, researchers tested a urine sample of the late U.S. Vice President Hubert Humphrey taken nine years before he was diagnosed with urinary cancer. The test showed the presence of DNA mutations.

Researchers are optimistic that these studies can push cancer detection up two, four or more years from its current position. New tests are being developed that search for more numerous DNA strands and are 200 times more sensitive than the original test. Major clinical research for these tests will begin next year.

Subject: Curcumin - Turmeric Extract

Curcumin

Turmeric- History and Traditional Usage

Native to Southeast Asia, Curcuma longa is a tall
tropical shrub with large oblong leaves and pale yellow flowers.
The genus “Curcuma” belongs to the Zingiberaceae family, which
includes ginger.1 The plant possesses a large root structure
with fleshy, bulbous underground parts called “rhizomes.” These
rhizomes, known as turmeric root, are harvested at maturity,
dried and cured for commercial use. Chemical analysis shows that
dried turmeric contains essential and volatile oils, with a
curcuminoid content of 2.5 to 5.0 %.2

In addition to its
popularity as a spice, turmeric is used as a dye for cloth and
coloring agent in foods and cosmetics, thanks to its rich yellow
color. Turmeric also serves as a preservative, probably owing to
the antioxidant and antimicrobial properties of curcumin.
Extracts of Curcuma longa have demonstrated in vitro
antibacterial and anti-fungal effects.3

Turmeric is named in
ancient Ayurvedic and Chinese herbal texts as a traditional folk
remedy. Historically, turmeric was used externally for wounds,
and sprains, and internally for digestive complaints,
rheumatism, liver disorders, coughs and colds.4

The numerous beneficial
effects attributed to turmeric stem in large measure from the
antioxidant properties of curcumin. Antioxidants neutralize free
radicals, which are highly unstable molecules that can damage
cellular structures through abnormal oxidative reactions.
Curcumin is a potent “scavenger” of the superoxide radical, a
free radical that initiates potentially harmful oxidative
processes such as lipid peroxidation.5 Through this activity,
curcumin has been shown to protect skin cells from the injurious
effect of nitroblue tetrazolium, a toxin that generates
superoxide radicals. Curcumin also increases survival of cells
exposed in vitro to the enzyme hypoxanthine/xanthine oxidase,
which stimulates superoxide and hydrogen peroxide production.
Curcumin itself is not toxic to cells, even at high
concentrations. Pure curcumin was shown to be less protective
than a mixture of curcuminoids, indicating a possible synergism
among curcuminoids.6 Because free radicals are involved in aging
and exert harmful effects on skin, these results suggest
curcumin may help slow skin aging.

Curcumin demonstrates
several other in vitro effects linked to free radical
scavenging. Curcumin scavenges nitric oxide, a compound
associated with the body’s inflammatory response.7 Pure curcumin
and turmeric extracts protect red blood cells from lipid
peroxidation induced by hydrogen peroxide.8 Curcumin has been
shown to protect DNA from oxidative damage, inhibit binding of
toxic metabolites to DNA, and reduce DNA mutations in the Ames’
test.9 Although additional studies suggest an anticarcinogenic
effect of curcumin, through protection of DNA,10 one in vitro
study found that curcumin induced DNA damage in human gastric
mucosal cells.11 It is speculated that curcumin may act as a
pro-oxidant in the presence of transition metal ions such as
copper and iron. (This is true for other antioxidants, including
vitamin C.) Curcumin also demonstrates in vitro inhibition of
COX-I and COX-II enzymes, which are involved in the inflammatory
reaction.12 Together these results strongly suggest that
curcumin is a potent bioprotectant with a potentially wide range
of therapeutic applications.

Animal studies- In vivo protective effects

Through its free radical scavenging
properties, curcumin has shown bioprotective effects in animals.
In one study, rats were treated with isoproterenol, a chemical
that causes cardiac hypertrophy (enlargement of the heart) due
to abnormal collagen metabolism. Co-treatment with curcumin
reversed the degradation of collagen and cardiac hypertrophy
induced by isoproterenol.13 Curcumin protects mice from
detrimental effects of radiation, by stabilizing the glyoxalase
system, a biological system that regulates cell division.14
Curcumin protects livers of rats from the damaging effects of
carbon tetrachloride (CCl4), a potent hepatoxin that injures the
liver via its free radical metabolite, CCl3.15,16 Curcumin
protected rats from alcohol-induced brain damage, in a study in
which oral administration of curcumin reversed lipid
peroxidation, reduced levels of free-radical metabolites and
increased levels of glutathione, a major physiologic
antioxidant.17 Curcuma longa extracts have shown
anti-inflammatory effects in rats.18

Human Trials

Curcumin exhibits free-radical scavenging ability when
administered to humans. In an open trial (uncontrolled), 18
healthy individuals ranging in age from 27 to 67 years consumed
a Curcuma longa extract, at a dose supplying 20 mg curcuminoids,
for 45 days. Before and after blood tests showed a statistically
significant decrease in lipid peroxides.19 Preliminary trials
have tested the anti-inflammatory action of curcumin, with
results that verify the traditional use of turmeric as an
anti-rheumatic herb. In a short-term double-blind, cross-over,
comparative study, 18 people received curcumin (1200 mg daily)
or phenylbutazone for two week periods. Both curcumin and
phenylbutazone produced measurable improvements in joint
flexibility and walking time. The subjects reported results only
with phenylbutazone, which may be explained by the short
duration of the trial.20 In a small placebo-controlled trial
comparing curcumin to phenylbutazone, 45 patients with
post-operative inflammation received curcumin, phenylbutazone or
placebo. The anti-inflammatory effects of curcumin and
phenylbutazone were comparable and superior to placebo.21
Curcumin has not been found to produce an analgesic (pain
relieving) effect.

Bioperine-Nature’s Absorption Enhancer
Boosts Curcumin Absorption*

Traditional Ayurvedic herbal
formulas often include black pepper and long pepper as
synergistic herbs. The active ingredient in both black pepper
and long pepper is the alkaloid, piperine. Experiments carried
out to evaluate the scientific basis for the use of peppers have
shown that piperine significantly enhances bioavailability when
consumed with other substances.22 Several double-blind clinical
studies have confirmed that Bioperine® increases absorption of
nutrients.23

Curcumin is poorly absorbed in the intestinal
tract, limiting its therapeutic effectiveness. Oral doses are
largely excreted in feces, and only trace amounts appear in the
blood. Concomitant administration of 20 mg of piperine with 2
grams of curcumin increases the bioavailability of curcumin by
2000%.24

Subject: Anti-Aging Nutrients

Anti-Aging Nutrients by Edward C. Wallace, DC, ND Energy Times, February 3, 2000

What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no traveler returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful, easy feeling.

How Do We Age?

Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD.

The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress.

Programmed Cell Theory

In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing.

Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging.

Free Radical/Oxidative Stress Theory

The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain. On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents.

Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution. Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster.

DNA Repair Theory

Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die.

What Can We Do?

The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging.

In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function."

Antioxidant Protection

Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit.

Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.) Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency.

In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725). Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly.

Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens.

Nutrition Deficiencies

A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15).

When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993).

A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage.

Longevity Diets

A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460).

Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers (Epidemiology 3[5], 1992: 389-391).

Staying Alive

Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines.

Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63).

In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat.

Longevity and Exercise

Exercise may slow aging. When researchers looked at the exercise habits of 17,000 men, average age of 46, they found that those who took part in vigorous activity lived longer.

Exercise can improve both cardiac and metabolic functions within the body, while also decreasing heart disease risk. Even modest exercise has been shown to improve cholesterol and blood sugar levels (JAMA 273[15], April 19, 1995: 1179-1184). In a study of how exercise affects your chances of living longer, 9,773 men underwent preventive medicine examinations on two different occasions. When the researchers looked at who lived longest, they found the highest death rate was in men who were unfit during both physical exams.

The Treadmill of Life

The lowest death rate was in the men who worked out and were in good shape. The researchers concluded that for each minute increase in how long a man could keep treading on a treadmill (between the first and second exam) there was a corresponding 7.9% decrease in the risk of dying (JAMA 273 [14], April 12, 1995: 1093-1098).

Since exercise can increase oxygen consumption up to 10 times, boosting the rate of production of free radicals, researchers believe that older individuals need more antioxidant nutrients to protect them. In a paper published in Aging Clinical and Experimental Research (1997), researchers stated that if you regularly exercise in your golden years, you should take more antioxidant vitamins to compensate for this risk.

Longevity Supplementation

Melatonin is not often thought of as an antioxidant, but, instead, as a sleep aid. Melatonin, however, is an effective and efficient free radical scavenger and may help stave off the effects of aging. Melatonin protects against what are called hydroxyl free radicals. Research shows that older people's lack of melatonin may make them more susceptible to oxidative stress. In one study, researchers felt that new therapies aimed at stimulating melatonin synthesis may eventually lead to therapies for the prevention of diseases related to premature aging (Aging and Clinical Experimental Research 7[5], 1995: 338-339). Melatonin was shown to provide antioxidant protection in several ways.

Toning Down Enzymes

Melatonin can ease the effects of enzymes that generate free radicals, enhance the production of glutathione peroxidase (an antioxidant) and defuse the caustic action of free radicals that contain hydroxyls. In several studies, DHEA supplementation has been shown to potentially revive immune function in older adults (Exp. Opin. Invest. Drugs 4[2], 1995: 147-154).

In a study of 138 persons older than 85 years compared to 64 persons 20 to 40 years of age, scientists found that the younger people had four times as much DHEA in their bodies.

The researchers believe that our bodies make less and less DHEA as we get older. The authors of this study raise the possibility that declining DHEA may be partly to blame for our biological clocks running down (New York Academy of Sciences 1994: 543-552).

Vitamins E & C

A growing body of research also supports the benefits of taking vitamins E and C to hold off the effects of getting old. Researchers writing in Free Radicals and Aging (1992: 411-418) point out that as you get older your body is home to more and more free radical reactions that may lead to degenerative diseases like heart disease and arthritis. Research has found that in older people with exercise-induced oxidative stress, taking vitamin E every day may significantly fight off free radicals. (To investigate this effect, scientists measured waste products in urine that result from free radical reactions.) Their conclusion: Dietary antioxidants such as vitamin E may be beneficial.

Chronological Age Vs.Biological Age

Vitamin C also looks to scientists like a good anti-aging bet. Research in the Journal of Advancement in Medicine, (7[1], Spring 1994: 31-41) showed that folks consuming larger amounts of vitamin C were less likely to experience clinical problems at all ages. Those taking in less than 100 mg of vitamin C per day also suffered the most problems.

In this research, individuals over 50 years of age who daily consumed the largest amount of vitamin C were as healthy or healthier than the 40 year olds who were taking the least amount of vitamin C.

Similar Relationship

A similar relationship appears to exist for vitamin E and serum cholesterol levels. In a study of 360 physicians and their spouses, researchers found that people in their 50s who consumed more vitamin E had lower cholesterol than those in their 30s who were taking less.

And the longevity beat goes on: In a study evaluating environmental tobacco smoke and oxidative stress, researchers divided 103 people into three groups. Researchers blew smoke at 37 of these folks without protection while 30 of them got to breathe tobacco smoke but took antioxidant supplementation. Another 36 of them merely had to read magazines from doctors' offices. The results: After 60 days of supplementation the antioxidant folks had a 62% reduction in evidence of oxidative damage to their DNA. Cholesterol levels dropped and so did antioxidant enzyme activities. The researchers concluded that taking antioxidants provided a modicum of protection against environmental poisons.

The range of antioxidant nutrients used in this study included: beta-carotene, vitamin C, vitamin E, zinc and selenium as well as copper (Cancer Epidemiol Biomarkers Prev 7, November 1998: 981-988).

Carotenoids

When you mention carotene or carotenoids, most people think of the beta carotene that makes carrots orange. But more than 600 carotenoids are present in colorful vegetables and many of these misunderstood substances are more potent antioxidants than beta-carotene.

Carotenoids have been shown to destroy oxygen free radicals in lipids (fats), help protect our cells from the sun's ultra violet radiation and enhance our natural immune response (J. Nutr 119[1], Jan. 1989: 112-115).

Some evidence seems to show that how much carotenoids you (and other mammals) have in your cells may be the predominant factor in determining life span (Proc Natl Acad Sci 82 [4], 1985: 798-802). Therefore, a diet rich in carotenoids (leafy green vegetables, carrots, yams, sweet potatoes, squash, citrus fruits and tomatoes) along with supplementation seems to be just what the fountain of youth ordered.

Flavonoids

Flavonoids, a group of antioxidant plant pigments, seem to be able to protect specific organs. For instance, the flavonoids in milk thistle (Silybum marianum) have been used for ages for liver problems. Bilberry has been found protective for the eye and hawthorn for the heart and circulatory system.

Numerous studies have shown the many beneficial effects of flavonoids with perhaps the best known being the ability of anthocyanidins in wine and grape seed extract to help protect your blood vessels and capillaries from oxidative damage (Phytotherapy 42, 1986: 11-14; Am J Clin Nutr 61, 1995: 549-54).

Flavonoids are found in vegetables and such fruits as blackberries, blueberries, cherries and grapes. A diet rich in these foods helps ensure an adequate intake of these important nutrient compounds.

Amino Acid Health

Methionine and cysteine are sulphur containing amino acids (protein building blocks), both of which are essential in maintaining levels of glutathione, a substance that plays a major role in quelling free radicals. Studies have found that as we age, the level of these important amino acids in our bodies decreases. (NEJM 312 [1], 1985: 159-68). As it has been shown that adding cysteine to the diet of test animals can increase their life expectancy considerably, researchers believe these amino acids can help us live longer too.

Attitude & Behavior

Get more sleep! A recent study showed that men who habitually napped were less likely to have a heart attack. The men in this research who regularly napped for at least 30 minutes per day had about a 30% reduction in heart problems while those who napped for a full hour had a 50% reduction compared to non nappers. Naps of longer duration did not seem to increase the benefit. In the same research, investigators also found that spending time with a pet or merely contemplating nature could also improve cardiac health. Sensuality, optimism and altruism also appeared to have health benefits (Family Practice News, December 15, 1998: 14-15).

In another study, this one in American Psychologist, researchers from the University of California found that people who are self-indulgent, pampered and achieve by running roughshod over the competition are less likely to outlive their healthy peers. Being egocentric, impulsive, undependable and tough-minded were predictors of poor physical health and a shorter life. So loosen up and be nice to your fellow humans! (U.C. Davis Magazine, Fall 1995: 14).

Longevity at Last

While no one has suggested that taking supplements, eating vegetables or exercising can, as of yet, extend the human life span past the generally recognized limit of about 120 years, researchers believe they can improve your odds of longer life. And by staying healthier, your old age will be more enjoyable, too.

Subject: Menopause: Disease or Condition?

Menopause: Disease or Condition?

by Mary Ann Mayo & Joseph L. Mayo, MD Energy Times, September 4, 1999

It's front-page news. It's politically correct and socially acceptable. Talking about menopause is in. Suddenly it's cool to have hot flashes. Millions of women turning 50 in the next few years have catapulted the subject of menopause into high-definition prominence.

It's about time. Rarely discussed openly by women (what did your mother ever advise you?), meno-pause until recently was dismissed as "a shutting down experience characterized by hot flashes and the end of periods." Disparaging and depressing words like shrivel, atrophy, mood swings and melancholia peppered the scant scientific menopausal literature.

What a difference a few years and a very vocal, informed and assertive group of Baby Boomers make. Staggered by the burgeoning numbers of newly confrontational women who will not accept a scribbled prescription and a pat on the head as adequate treatment, health practitioners and researchers have been challenged to unravel, explain and deal with the challenges of menopause.

Not An Overnight Sensation

Menopause, researchers have discovered, is no simple, clear cut event in a woman's life. The "change of life" does not occur overnight. A woman's body may begin the transition toward menopause in her early 40s, even though her last period typically occurs around age 51. This evolutionary time before the final egg is released is called the perimenopause. Erratic monthly hormone levels produce unexpected and sometimes annoying sensations.

Even as their bodies adjust to lower levels of estrogen, progesterone and testosterone, some women don't experience typical signs of menopause until after the final period. A fortunate one-third have few or no discomforts.

Hormonal Events

According to What Your Doctor May Not Tell You About Premenopause (Warner Books) by John R. Lee, MD, Jesse Hanley, MD, and Virginia Hopkins, "The steroid hormones are intimately related to each other, each one being made from another or turned back into another depending on the needs of the body...But the hormones themselves are just part of the picture. It takes very specific combinations of vitamins, minerals and enzymes to cause the transformation of one hormone into another and then help the cell carry out the hormone's message. If you are deficient in one of the important hormone-transforming substances such as vitamin B6 or magnesium, for example, that too can throw your hormones out of balance. Thyroid and insulin problems, toxins, bad food and environmental factors, medication and liver function affect nutrient and hormone balance."

The most important reproductive hormones include:

Estrogen: the female hormone produced by the ovaries from puberty through menopause to regulate the menstrual cycle and prepare the uterus for pregnancy. Manufacture drops significantly during menopause. Estradiol is a chemically active and efficient form of estrogen that binds to many tissues including the uterus, breasts, ovaries, brain and heart through specific estrogen receptors that allow it to enter those cells, stimulating many chemical reactions. Estriol and estrone are additional forms of estrogen.

Progesterone: also produced by the ovaries, it causes tissues to grow and thicken, particularly during pregnancy, when it protects and nurtures the fetus. Secretion ceases during menopause.

Testosterone: Women produce about one-twentieth of what men do, but require it to support sex drive. About half of all women quit secreting testosterone during menopause.

Estrogen's Wide Reach

Since estrogen alone influences more than 400 actions on the body, chiefly stimulating cell growth, the effects of its fluctuations can be far-reaching and extremely varied: hot (and cold) flashes, erratic periods, dry skin (including the vaginal area), unpredictable moods, fuzzy thinking, forgetfulness, fatigue, low libido, insomnia and joint and muscle pain.

Young women may experience premature menopause, which can occur gradually, as a matter of course, or abruptly with hysterectomy (even when the ovaries remain) or as a result of chemotherapy. Under such conditions symptoms can be severe.

In the 1940s doctors reasoned that if most discomforts were caused by diminishing estrogen (its interactive role with progesterone and testosterone were underestimated), replacing it would provide relief. When unchecked estrogen use resulted in high rates of uterine cancer, physicians quickly began adding progesterone to their estrogen regimens and the problem appeared solved.

For the average woman, however, hormone replacement therapy (HRT) became suspect and controversial, especially when a link appeared between extended use of HRT (from five to 10 years) and an increase in breast and endometrial cancers (Journal of Clinical Pharmacology 37, 1997). The result: Women have drawn a line in the sand between themselves and their doctors.

Resolving The Impasse

Since hormone replacement reduces the risk of major maladies like heart disease, osteoporosis, Alzheimer's, colon cancer and diabetes that would otherwise significantly rise as reproductive hormone levels decrease, most doctors recommend hormone replacement shortly before or as soon as periods stop. Hormone replacement also alleviates the discomforts of menopause.

But only half of all women fill their HRT prescriptions and, of those who do, half quit within a year. Some are simply indifferent to their heightened medical risks. Some are indeed aware but remain unconvinced of the safety of HRT. Others complain of side effects such as bloating, headaches or drowsiness.

Women's resistance to wholesale HRT has challenged researchers to provide more secure protection from the diseases to which they become vulnerable during menopause, as well as its discomforts. If the conventional medical practitioners do not hear exactly what modern women want, the complementary medicine community does. Turning to centuries-old botanicals, they have validated and compounded them with new technology. Their effectiveness depends on various factors including the synergistic interaction of several herbs, specific preparation, the correct plant part and dosage, harvesting and manufacturing techniques.

Research demonstrates that plant hormones (phytoestrogens) protect against stronger potentially carcinogenic forms of estrogen while safely providing a hormone effect. Other herbs act more like tonics, zipping up the body's overall function.

Help From Herbs

Clinical trials and scientific processing techniques have resulted in plant-based supplements like soy and other botanicals that replicate the form and function of a woman's own estrogen.

The complementary community also can take credit for pushing the conventional medical community to look beyond estrogen to progesterone in postmenopausal health.

Natural soy or Mexican yam derived progesterone is formulated by pharmacologists in creams or gels that prevent estrogen-induced overgrowth of the uterine lining (a factor in uterine cancer), protect against heart disease and osteoporosis and reduce hot flashes (Fertility and Sterility 69, 1998: 96-101).

A quarter of the women who take the popularly prescribed synthetic progesterone report increased tension, fatigue and anxiety; natural versions have fewer side effects.

These "quasi-medicines," as Tori Hudson, a leading naturopathic doctor and professor at the National College of Naturopathic Medicine, Portland, Oregon, calls them, are considered "stronger than a botanical but weaker than a medicine." (Hudson is author of Gynecology and Naturopathic Medicine: A Treatment Manual.)

According to Hudson, the amount of estrogen and progesterone in these supplements is much less than medical hormone replacement but equally efficacious in relieving menopausal problems and protecting the heart and bones.

According to a study led by Harry K. Genant, PhD, of the University of California, San Francisco, "low-dose" plant estrogen derived from soy and yam, supplemented with calcium, prevents bone loss without such side effects as increased vaginal bleeding and endometrial hypoplasia, abnormal uterine cell growth that could be a precursor to endometrial cancer (Archives of Internal Medicine 157, 1997: 2609-2615).

These herbal products, including natural progesterone and estrogen in the form of the weaker estriol or estrone, may block the effect of the stronger and potentially DNA-damaging estradiol.

Soy in its myriad dietary and supplemental forms provides a rich source of isoflavones and phytosterols, both known to supply a mild estrogenic effect that can stimulate repair of the vaginal walls (Journal of the National Cancer Institute 83, 1991: 541-46).

To enhance vaginal moisture, try the herb cimicifuga racemosa, the extract of black cohosh that, in capsule form, builds up vaginal mucosa (Therapeuticum 1, 1987: 23-31). Traditional Chinese herbal formulas containing roots of rehmannia and dong quai have long been reputed to promote vaginal moisture.

Clinical research in Germany also confirms the usefulness of black cohosh in preventing hot flashes and sweating, as well as relieving nervousness, achiness and depressed moods caused by suppressed hormone levels. It works on the hypothalamus (the body's thermostat, appetite and blood pressure monitor), pituitary gland and estrogen receptors. Green tea is steeped with polyphenols, mainly flavonoids, that exert a massive antioxidant influence against allergens, viruses and carcinogens. The risks of estrogen-related cancers such as breast cancer are particularly lowered by these flavonoids, as these substances head directly to the breast's estrogen receptors. About three cups a day exert an impressive anti-inflammatory, antiallergenic, antiviral and anticarcinogenic effect.

Other phytoestrogen-rich botanicals, according to Susun Weed's Menopausal Years: The Wise Woman Way (Ash Tree Publishing), include motherwort and lactobacillus acidophilus to combat vaginal dryness; hops and nettles for sleep disturbances; witch hazel and shepherd's purse for heavy bleeding; motherwort and chasteberry for mood swings; dandelion and red clover for hot flashes.

Our Need For Supplements

Adding micronutrients at midlife to correct and counter a lifetime of poor diet and other habits is a step toward preventing the further development of the degenerative diseases to which we become vulnerable. At the very minimum, you should take:

a multivitamin/mineral supplement vitamin E calcium

Your multivitamin/mineral should contain vitamins A, B complex, C, D, E, calcium, magnesium, potassium, copper and zinc. Look for a wide variety of antioxidants that safeguard you from free radical damage, believed to promote heart disease and cancer, as well as contribute to the aging process.

Also on the list: mixed carotenoids such as lycopene, alpha carotene and vitamin C; and folic acid to help regulate cell division and support the health of gums, red blood cells, the gastrointestinal tract and the immune system.

Studies indicate a deficiency of folic acid (folate) in 30% of coronary heart disease, blood vessel disease and strokes; lack of folate is thought to be a serious risk factor for heart disease (OB.GYN News, July 15, 1997, page 28).

Extra vitamin E is believed to protect against breast cancer and bolster immune strength in people 65 and older (Journal of the American Medical Association 277, 1997: 1380-86). It helps relieve vaginal dryness, breast cysts and thyroid problems and, more recently, hit the headlines as an aid in reducing the effects of Alzheimer's and heart disease. It is suspected to reduce the thickening of the carotid arterial walls and may prevent the oxidation of LDL (bad) cholesterol, which contributes to the formation of plaque in arteries.

Selenium also has been identified as an assistant in halting cancer (JAMA 276, 1996: 1957-63).

The Omegas To The Rescue

Essential fatty acids found in cold water fish, flaxseed, primrose and borage oils and many nuts and seeds are essential for the body's production of prostaglandin, biochemicals which regulate hormone synthesis, and numerous physiological responses including muscle contraction, vascular dilation and the shedding of the uterine lining. They influence hormonal balance, reduce dryness and relieve hot flashes.

In addition, the lignans in whole flaxseed behave like estrogen and act aggressively against breast cancer, according to rat and human studies at the University of Toronto (Nutr Cancer 26, 1996: 159-65).

Research has demonstrated that these omega-3 and omega-6 fatty acids can reverse the cancer-causing effects of radiation and other carcinogens (Journal of the National Cancer Institute 74, 1985: 1145-50). Deficiencies may cause swelling, increased blood clotting, breast pain, hot flashes, uterine and menstrual cramps and constipation. Fatigue, lack of endurance dry skin and hair and frequent colds may signal EFA shortage. Plus, fatty fish oils, along with vitamin D and lactose, help absorption of calcium, so vital for maintaining bone mass.

In addition, studies show that the natural substance Coenzyme A may help menopausal women reduce cholesterol and increase fat utilization (Med Hyp 1995; 44, 403, 405). Some researchers belive Coenzyme A plays a major role in helping women deal with stress while strengthening immunity.

Still Suffering?

Can't shake those menopausal woes? Menopause imposters may be imposing on you: The risk of thyroid disease, unrelenting stress, PMS, adrenal burnout, poor gastrointestinal health and hypoglycemia all increase at midlife. Menopause is a handy hook on which to hang every misery, ache and pain but it may only mimic the distress of other ailments. For this reason every midlife woman should have a good medical exam with appropriate tests to determine her baseline state of health. Only with proper analysis can you and your health practitioner hit on an accurate diagnosis and satisfying course of therapy.

And if menopause is truly the issue, you have plenty of company. No woman escapes it. No woman dies from it. It is not a disease but a reminder that one-third of life remains to be lived. Menopausal Baby Boomers can anticipate tapping into creative energy apart from procreation. If not new careers, new interests await. An altered internal balance empowers a menopausal woman to direct, perhaps for the first time, her experience of life. She has come of age-yet again. Gone is the confusion, uncertainty, or dictates of a hormone driven life: This time wisdom and experience direct her. There is no need to yearn for youth or cower at the conventional covenant of old age. Menopause is the clarion call to reframe, reevaluate and reclaim.

Subject: Nutrients for Longevity

Nutrients for Longevity by Edward C. Wallace, ND, DC Energy Times, September 1, 1999

What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no traveler returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful easy feeling.

How Do We Age

Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD.

The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress.

Programmed Cell Theory

In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing.

Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging.

Free Radical/Oxidative Stress Theory

The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain.

On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents. Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution.

Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster.

DNA Repair Theory

Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die.

What Can We Do

The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging.

In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function."

Antioxidant Protection

Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit.

Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.)

Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency.

In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725).

Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly.

Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens.

Nutrition Deficiencies

A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15).

When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993).

A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage.

Longevity Diets

A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460)

Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers. (Epidemiology 3[5], 1992: 389-391).

Staying Alive

Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines.

Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects. (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63).

In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat.

Longevity and Exercise:

Exercise may slow aging. When researchers looked at the exercise habits of 17,000 men, average age of 46, they found that those who took part in vigorous activity lived longer.

Exercise can improve both cardiac and metabolic functions within the body, while also decreasing heart disease risk. Even modest exercise has been shown to improve cholesterol and blood sugar levels (JAMA 273[15], April 19, 1995: 1179-1184).

In a study of how exercise affects your chances of living longer, 9,773 men underwent preventive medicine examinations on two different occasions. When the researchers looked at who lived longest, they found the highest death rate was in men who were unfit during both physical exams.

The Treadmill of Life

The lowest death rate was in the men who worked out and were in good shape. The researchers concluded that for each minute increase in how long a man could keep treading on a treadmill (between the first and second exam) there was a corresponding 7.9% decrease in the risk of dying. (JAMA 273 [14], April 12, 1995: 1093-1098).

Since exercise can increase oxygen consumption up to 10 times, boosting the rate of production of free radicals, researchers believe that older individuals need more antioxidant nutrients to protect them. In a paper published in Aging Clinical and Experimental Research (1997), researchers stated that if you regularly exercise in your golden years, you should take more antioxidant vitamins to compensate for this risk.

Longevity Supplementation

Melatonin is not often thought of as an antioxidant, but, instead, as a sleep aid. Melatonin, however, is an effective and efficient free radical scavenger and may help stave off the effects of aging.

Melatonin protects against what are called hydroxyl free radicals. Research shows that older people's lack of melatonin may make them more susceptible to oxidative stress. In one study, researchers felt that new therapies aimed at stimulating melatonin synthesis may eventually lead to therapies for the prevention of diseases related to premature aging (Aging and Clinical Experimental Research 7[5], 1995: 338-339). Melatonin was shown to provide antioxidant protection in several ways.

Toning Down Enzymes

Melatonin can ease the effects of enzymes that generate free radicals, enhance the production of glutathione peroxidase (an antioxidant) and defuse the caustic action of free radicals that contain hydroxyls.

In several studies, DHEA supplementation has been shown to potentially revive immune function in older adults (Exp. Opin. Invest. Drugs 4[2], 1995: 147-154).

In a study of 138 persons older than 85 years compared to 64 persons 20 to 40 years of age, scientists found that the younger people had four times as much DHEA in their bodies.

The researchers believe that our bodies make less and less DHEA as we get older. The authors of this study raise the possibility that declining DHEA may be partly to blame for our biological clocks running down (New York Academy of Sciences 1994: 543-552).

Vitamins E & C

A growing body of research also supports the benefits of taking vitamins E and C to hold off the effects of getting old. Researchers writing in Free Radicals and Aging (1992: 411-418) point out that as you get older your body is home to more and more free radical reactions that may lead to degenerative diseases like heart disease and arthritis. Research has found that in older people with exercise-induced oxidative stress, taking vitamin E every day may significantly fight off free radicals. (To investigate this effect, scientists measured waste products in urine that result from free radical reactions.) Their conclusion: Dietary antioxidants such as vitamin E may be beneficial.

Chronological Age Vs. Biological Age

Vitamin C also looks to scientists like a good anti-aging bet. Research in the Journal of Advancement in Medicine, (7[1], Spring 1994: 31-41) showed that folks consuming larger amounts of vitamin C were less likely to experience clinical problems at all ages. Those taking in less than 100 mg of vitamin C per day also suffered the most problems. In this research, individuals over 50 years of age who daily consumed the largest amount of vitamin C were as healthy or healthier than the 40 year olds who were taking the least amount of vitamin C.

Similar Relationship

A similar relationship appears to exist for vitamin E and serum cholesterol levels. In a study of 360 physicians and their spouses, researchers found that people in their 50s who consumed more vitamin E had lower cholesterol than those in their 30s who were taking less. And the longevity beat goes on: In a study evaluating environmental tobacco smoke and oxidative stress, researchers divided 103 people into three groups. Researchers blew smoke at 37 of these folks without protection while 30 of them got to breathe tobacco smoke but took antioxidant supplementation. Another 36 of them merely had to read magazines from doctors' offices. The results: After 60 days of supplementation the antioxidant folks had a 62% reduction in evidence of oxidative damage to their DNA. Cholesterol levels dropped and so did antioxidant enzyme activities. The researchers concluded that taking antioxidants provided a modicum of protection against environmental poisons.

The range of antioxidant nutrients used in this study included: beta-carotene, vitamin C, vitamin E, zinc and selenium as well as copper (Cancer Epidemiol Biomarkers Prev 7, November 1998: 981-988).

Carotenoids

When you mention carotene or carotenoids, most people think of the beta carotene that makes carrots orange. But more than 600 carotenoids are present in colorful vegetables and many of these misunderstood substances are more potent antioxidants than beta-carotene.

Carotenoids have been shown to destroy oxygen free radicals in lipids (fats), help protect our cells from the sun's ultra violet radiation and enhance our natural immune response (J. Nutr 119(1), Jan. 1989: 112-115).

Some evidence seems to show that how much carotenoids you (and other mammals) have in your cells may be the predominant factor in determining life span (Proc Natl Acad Sci 82 [4], 1985: 798-802). Therefore, a diet rich in carotenoids (leafy green vegetables, carrots, yams, sweet potatoes, squash, citrus fruits and tomatoes) along with supplementation seems to be just what the fountain of youth ordered.

Flavonoids

Flavonoids, a group of antioxidant plant pigments, seem to be able to protect specific organs.

For instance, the flavonoids in milk thistle (Silybum marianum) have been used for ages for liver problems. Bilberry has been found protective for the eye and hawthorn for the heart and circulatory system.

Numerous studies have shown the many beneficial effects of flavonoids with perhaps the best known being the ability of anthocyanidins in wine and grape seed extract to help protect your blood vessels and capillaries from oxidative damage (Phytotherapy 42, 1986: 11-14; Am J Clin Nutr 61, 1995: 549-54).

Flavonoids are found in vegetables and such fruits as blackberries, blueberries, cherries and grapes. A diet rich in these foods helps ensure an adequate intake of these important nutrient compounds.

Amino Acid Health

Methionine and cysteine are sulphur containing amino acids (protein building blocks), both of which are essential in maintaining levels of glutathione, a substance that plays a major role in quelling free radicals. Studies have found that as we age, the level of these important amino acids in our bodies decreases. (NEJM 312 [1], 1985: 159-68).

As it has been shown that adding cysteine to the diet of test animals can increase their life expectancy considerably, researchers believe these amino acids can help us live longer too.

Attitude & Behavior

Get more sleep! A recent study showed that men who habitually napped were less likely to have a heart attack. The men in this research who regularly napped for at least 30 minutes per day had about a 30% reduction in heart problems while those who napped for a full hour had a 50% reduction compared to non nappers. Naps of longer duration did not seem to increase the benefit.

In the same research, investigators also found that spending time with a pet or merely contemplating nature could also improve cardiac health. Sensuality, optimism and altruism also appeared to have health benefits (Family Practice News, December 15, 1998: 14-15).

In another study, this one in American Psychologist, researchers from the University of California found that people who are self-indulgent, pampered and achieve by running roughshod over the competition are less likely to outlive their healthy peers. Being egocentric, impulsive, undependable and tough-minded were predictors of poor physical health and a shorter life. So loosen up and be nice to your fellow humans! (U.C. Davis Magazine, Fall 1995: 14).

Longevity at Last

While no one has suggested that taking supplements, eating vegetables or exercising can, as of yet, extend the human life span past the generally recognized limit of about 120 years, researchers believe they can improve your odds of living longer. An added benefit: By staying healthier, your old age won't only be longer, it will be more enjoyable, too.

And, who knows, if you hang around long enough, taking your nutrients and getting a comfortable amount of consistent exercise, while meditating and refusing to succumb to stress, that magic bullet that will keep you alive for centuries may be discovered. Some day a new antioxidant or other substance may finally prove to provide the elusive fountain of youth. Stay tuned.

Subject: Breast Cancer

Breast Cancer by Joseph L. Mayo,MD Mary Ann Mayo, MA Energy Times, May 2, 1999

What do you fear most? Bankruptcy? Floods? Heart disease? If you're like many women, breast cancer stands near the top of that dreaded list.

But that fear doesn't permeate other cultures the way it does ours.

A woman like Mariko Mori, for instance, 52 years old, Japanese, worries about intense pressures beginning to burden her toddler grandson. But worry about breast cancer? Hardly.

In Indiana, Mary Lou Marks, 50, has similar family frets, mulling over her 28-year-old daughter's career choice.

But on top of that, when Mary Lou tabulates her other worries, she recoils at the thought of breast cancer. She's heard about her lifetime risk: 1 in 8. Meanwhile, Mariko's is merely 1 in 40, according to Bob Arnot's Breast Cancer Prevention Diet (Little, Brown).

American Problem
Experts reporting in "Women at High Risk for Breast Cancer: A Primary Care Perspective" (Prim Care Update Ob/Gyns, vol. 5, no. 6, 1998, p. 269) say the risk of developing breast cancer for the average American woman during ages 40 to 59 is 3.9%; by 60 to 79 years of age that rises to 6.9%. A high-risk 40-year-old has a 20% chance of breast cancer in the next 20 years.

New studies have found the effect of carrying the gene linked to breast cancer, which is responsible for only 5 to 10% of breast cancer incidence, is not as great as first suspected. Earlier estimates that the gene reflects an 80% chance of incurring breast cancer by age 70 has been recalculated to be only 37% (The Lancet, 1998;352:1337-1339).

Complex Causesbr> Researchers agree: No one factor is solely responsible for breast cancer. Risk depends on many factors, including diet, weight, smoking, alcohol consumption, activity level and, of course, those genes.

Regardless of their actual chance of getting breast cancer, women worry. Mary Lou faces no factors that would place her in particular jeopardy. But her anxieties about radical therapies and medical expenses paralyze her: She forgets to visit her health care provider and skips her annual mammogram appointments. Mary Lou's daughter, perhaps in reaction to her mother's gripping fears, campaigns ardently for cancer prevention, educating herself and mobilizing against the cumulative effects of known cancer risks. Smart young woman: A malignancy, after all, can take years to develop. A tumor must swell to one billion cells before it is detectable by a mammogram.

Dietary Benefits
Of all the tactics for reducing the risk of breast cancer, diet ranks high on the list.

The soy-rich regimen of Japanese women like Mariko Mori, for example, helps to explain the low breast cancer rates in Asian countries (see box at center of the page).

Tomatoes, because of their high quotient of the carotenoid lycopene, have been found to protect cells from the corrosive clutches of oxidants that have been linked with cancer in 57 out of 72 studies (The Santa Rosa Press Democrat, February 17, 1999, page A6, reporting on a Harvard Medical School study). For more on tomatoes see page 16.

But there's no one magic anti-cancer food or diet. Eating to prevent breast cancer requires a balanced menu with fiber, healthy fats, phytoestrogens and antioxidants, all fresh and free of chemical additives.

Modifying the balance and type of estrogen, the female sex hormone produced by the ovaries, offers an important breast cancer safeguard. Fat cells, adrenal glands and, before menopause, the ovaries, produce three "flavors" of estrogen, the strongest of which, estradiol, is believed to be carcinogenic when too plentiful or persistent in the body.

Estrogen does its work by attaching to estrogen receptors. Receptors are particularly numerous in the epithelial cells that line milk sacs and ducts in the breasts.

A receptor site is like a designated parking spot: Once estrogen is parked there it triggers one of its 400 functions in the body, from preparation of the uterus for pregnancy to intensifying nerve synapses in the brain.

The food we eat can be a source of estrogen; plant estrogens, called phytoestrogens, are much weaker than the body's estrogens, but they fit the same receptors. Phytoestrogens exert a milder estrogenic effect than bodily estrogen and are capable of blocking the more potent, damaging versions.

Finding Phytoestrogens
Foods high in phytoestrogens include vegetables, soy, flaxseed and herbs such as black cohosh, chasteberry, red clover and turmeric. Soy is the darling of the day for good reason. Both soy and flaxseed can lengthen periods, reducing the body's overall exposure to estrogen.

Soy also contains genistein, an "isoflavone" very similar in molecular form to estrogen but only 1/100,000 as potent. Because of its structure, genistein can attach to cells just as estrogen does; it also helps build carriers needed for binding estrogen and removing it from the body (Journal of Nutrition 125, no.3 [1995]:757S-770S). It acts as an antioxidant to counteract free radicals.

Tumor Inhibition
Studies have demonstrated that genistein inhibits angiogenesis (new tumor growth), slowing the progression of existing cancer.

Soy is most protective for younger women. Postmenopausal women benefit from soy's ability to diminish hot flashes and for cardiovascular protection, especially in combination with vitamin E, fiber and carotene (Contemporary OB/GYN, September 1998, p57-58).

Experts don't know that much about the cumulative effect of combining hormone replacement with soy, herbs and a diet high in phytoestrogens. Menopausal women who boost their estrogen this way should work with their health care providers and monitor their hormonal levels every six to 12 months with salivary testing.

The Vegetable Cart
Some vegetables are particularly protective against breast cancer because they change the way the body processes estrogen. Indol-3-carbinol, found in the co-called cruciferous vegetables such as cauliflower, broccoli and cabbage, diminishes the potency of estrogen. (Broccoli also contains isothiocyanates that trigger anti-carcinogenic enzymes.) These vegetables supply fiber, beta-carotene, vitamin C as well as other vitamins and minerals (Proc of the National Academy of Science USA, 89:2399-2403, 1992).

Fiber from fruits, vegetables and whole grains reduces insulin levels and suppresses the appetite by making make us feel full, thus helping with weight control, so important to resisting cancer. Fiber also helps build estrogen carriers that keep unbound estrogen from being recirculated and reattached to the breast receptors.

Cellulose, the fruit and vegetable fiber most binding with estrogen, also rounds up free radicals that damage DNA within cells.,p> Feeding the Immune System Despite heightened public awareness and efforts to stick to wholesome, healthful diets, experts increasingly link poor nutrition to depressed immune systems. Many Americans are at least marginally deficient in trace elements and vitamins despite their best attempts to eat well; that's why a good multivitamin/mineral is wise, even mandatory. Vitamins given to people undergoing cancer treatment stimulate greater response, fewer side effects, and increased survival (International Journal of Integrative Medicine, vol. 1, no. 1, January/February 1999).

Nutrients tend to work synergistically on the immune system. They should be taken in balanced proportions, and in consultation with your health care provider.

Immune Boosters
In Research links low levels of calcium and vitamin D, an inhibitor of cell division and growth, to higher breast cancer rates.

n Riboflavin (B2), pyridoxine (B6), pantothenic acid (B5), zinc and folate strengthen immunity. Selenium, in lab culture and animal studies, has helped kill tumors and protect normal tissues.

n Beta-carotene and vitamins A, E and C are antioxidants. Vitamin C enhances vitamin E's effects, boosting immunity and protecting against cell damage. The antioxidant isoflavones in green tea, with soy, convey the anticancer effects of the Asian diet. Research shows actions that discourage tumors and gene mutations.

The food you eat influences hormones. Excess sugar raises insulin, which acts as a growth factor for cancer and interferes with vitamin C's stimulation of white blood cells. It may contribute to obesity.

Alcohol is converted to acetaldehyde, which causes cancer in laboratory animals. It affects gene regulation by decreasing the body's ability to use folic acid. It increases estrogen and the amount of free estradiol in the blood. The liver damage that accompanies high alcohol consumption frequently reduces its capacity to filter carcinogenic products, regulate hormones and break down estrogen. Studies of alcohol consumption have caused experts to estimate that drinking more than two alcoholic beverages a day increases breast cancer risk by 63% (OB-GYN News, November 1, 1998, p. 12).

Fat Can be Phat
Fat conveys nutritional benefits. Not all fats are bad: we can't survive for very long without certain fats. Fat can turn you into a "well-oiled" machine. But the wrong kind of fat (the fatty acids in red meats and fatty poultry) is believed to be a major culprit in breast cancer.

Fat cells produce estrogen. Excess fat stores carcinogens and limits carriers that can move estrogen out of your system.

Once estrogen has attached itself to a receptor, the health result depends on the type of fat in the breast. Saturated fat, transfatty acids and omega-6 fat from polyunsaturated vegetable oils such as safflower oil, peanut, soybean oil, corn oil and in margarine can increase the estrogen effect and trigger a powerful signal to the breast cell to replicate.

Restraining Prostaglandins
Blood rich in the essential fatty acids omega-3 and omega-9 lowers cancer risk by driving down levels of prostaglandins, which promote tumor growth. The blood and tumors of women with breast cancer usually contain high levels of prostaglandins.

Breast tissue is protected by omega-3 fat chiefly from fish and flaxseed and by omega-9 from olive oil. Salmon once a week or water packed tuna three times a week are particularly beneficial. Fish oil supplements processed to reduce contaminates are available. Cod liver oil isn't recommended: its vitamin A and D levels are too high.

Flaxseed is the richest known plant source of omega-3. Use a coffee grinder to benefit from the seed and oil for the full estrogen effect; sprinkle ground flaxseed over cereal or fold into baked goods. Drizzle flaxseed oil, found in the refrigerator section of your health food store, over salads or cereal. (Store the oil in the refrigerator.)

Olive oil, especially in the context of the so-called Mediterranean diet of vegetables, omega-3-rich fish and fresh fruit (Menopause Management, January-February 1999, p. 16-19), lowers the risk of breast cancer (The Lancet, May 18, 1996;347:1351-1356).

Selecting Organic Food
Select organic foods for extra anticancer protection. Pesticides stimulate erratic cell action and often inhibit the estrogen carrier's ability to attach and remove estrogen from the body. Free floating estrogen then can attach to breast receptors and cause trouble.

Buy or grow fresh, organic foods whenever you can. When grilling meat, fish or poultry, reduce the area where carcinogens may accumulate by trimming fat. Charred, well-done meat is known to be carcinogenic. When grilling, marinate meat first and reduce the cooking time on the grill by slightly precooking.

Cancer prevention is an interlocking puzzle requiring the limitation of fat consumption, weight control, exercise, stress reduction and care for psychological and spiritual balance. Possessing more cancer fighting pieces makes you more likely to be able to complete the prevention picture.

The Latest Breakthroughs in Garlic Research

on Cancer and Cardiovascular Disease

Presented at the 2005 World Garlic Symposium

Many of the world’s top-level scientists gathered in Washington D.C. this week for the 2005 Garlic Symposium, entitled, “Significance of Garlic and its Constituents in Cancer and Cardiovascular Disease.” The conference provided current scientific information about the effect of garlic and its constituents on health and performance. The symposium was held at the Georgetown University Conference Center on April 9-11, 2005.

“For the first time in seven years authorities in various fields of garlic research from all over the world to provide the latest updates, specifically regarding aged garlic extract and its actions in diseased states including heart disease and cancer,” commented Dr. Matthew Budoff, M.D. cardiovascular researcher at UCLA. “Garlic has been used medicinally for thousands of years in virtually all ancient cultures. Now, new metabolic roles for garlic are being proposed and there are many promising lines of research.”

Presentation highlights included:

• Anti-glycation properties of aged garlic extract: possible role in prevention of diabetic complications, presented by Nessar Ahmed, Manchester Metropolitan University in England Aged garlic extract inhibited the formation of advanced glycation end products, which have been previously shown to increase the risk of diabetic complications ranging from heart disease to retinopathy, kidney failure, impaired wound healing and many more.

“Garlic is turning out to be a major player in cancer and heart disease prevention and control, especially in combination with drug treatments,” said Richard Rivlin, M.D. of Strang Cancer Prevention Center at Cornell. “It’s also showing us that we can start early. It’s madness to treat cancer and heart disease in their advanced stages. We need to start early and aged garlic extract is an excellent way to do that.”

Almost 400 scientific studies have been completed on aged garlic extract, done in major universities worldwide. These studies have focused on a variety of heart disease risk factors such as cholesterol, high blood pressure, homocysteine levels, inhibiting LDL oxidation, anti-platelet aggregation and adhesion, stimulating blood circulation; in addition to other studies on immune stimulation, cognitive effects, liver function and anti-tumor effects. .

Abstracts

PRECLINICAL PERSPECTIVE ON GARLIC AND CANCER. John A. Milner, National Cancer Institute, Rockville, MD 20892

Mounting evidence points to the anticancer properties of fresh garlic extracts, aged garlic, garlic oil, and a number of specific organosulfur compounds from garlic. These prevention characteristics arise through both a dose and temporal related change in several cellular events including those involving drug metabolism, immunocompetence, cell cycle regulation, apoptosis and angiogenesis. A block in carcinogen activation through modulation of cytochrome P450-dependent monooxygenases and/or acceleration of carcinogen detoxification via induction of phase II enzymes likely account for some of this protection. The block in preneoplastic lesions and/or tumors in several sites suggests a generalizable mechanism. The efficacy of water- and lipid-soluble allyl sulfur compounds against chemical carcinogenesis appears comparable, although more studies are needed. A shift in sulfhydryl groups, redox status or enzyme catalysis may account for some of the phenotypic changes. They may also account for the observed hyperphosphorylation of specific cell cycle related proteins and histone hyperacetylation; both of which have been correlated with suppressed tumor cell proliferation. Several forms of allyl sulfur compounds are effective in blocking cell division and inducing apoptosis, but notable differences in the efficacy among these various compounds and across tumor types are evident. While the expression of many genes and proteins can be influenced by allyl sulfides; the challenge is to determine which is responsible for a phenotypic change. Additional studies are needed with more modest exposures and over prolonged periods and that utilize transgenic and knockout models to assist in the identification of molecular targets. Finally, additional research is needed to identify sensitive “effect” and “susceptibility” biomarkers that can ultimately be used to identify responders from non-responders.

INHIBITION OF CORONARY ARTERIAL PLAQUE ACCUMULATION BY GARLIC. Matthew Budoff, Harbor-UCLA Medical Center, UCLA School of Medicine, California, USA

Effect of Aged garlic extract (AGE) has been tested in the placebo-controlled double blind randomized clinical study to determine whether the atherosclerotic plaque burden detected by electron beam tomography (EBT) will change at a different rate under the influence of AGE or placebo. EBT can non-invasively quantitate the amount of coronary calcification and track atherosclerotic plaque over time. Nineteen of 23 patients completed the study protocol. The patients were well matched for age, gender, statin use and cardiac risk factors. Patients underwent EBT and blood testing at baseline, and then again after 12 months of randomization. The average change in the calcium score (Volumetric method) ± SD for the AGE group (n = 9) was 7.5 ± 9.4% over the one year. The placebo group (n = 10) demonstrated 22.2 ± 18.5% annual progression, significantly greater than the treated cohort (p = 0.01). While there were no significant changes in cholesterol parameters, or C Reactive protein between the groups, high density lipoproteins and plasma homocysteine in the AGE group demonstrated a trend toward improvement compared to the placebo patients. Thus, although this is a small-scale trial, it demonstrates the potential of AGE to inhibit the rate of atherosclerosis (progression of coronary calcium), as compared to placebo over one year. Larger studies need to be performed to assess this potential anti-atherosclerotic therapy and the impact on coronary events.

INFLUENCE OF GARLIC ON ENDOTHELIAL DYSFUNCTION IN HYPERHOMOCYSTEINEMIA. N. Weiss, N. Ide, T. Abahji, L. Nill, C. Keller, U. Hoffmann. Klinikum der Universität München, D-80336 Munich, Germany

Endothelial dysfunction (ED) due to decreased bioavailable nitric oxide (NO) by increased vascular oxidant stress plays a critical role in the vascular pathobiology of hyperhomocysteinemia (hhcy). Aged Garlic Extract (AGE) minimizes intracellular oxidant stress and stimulates NO generation in endothelial cells. We performed a placebo-controlled, blinded, cross-over study to examine whether AGE prevents macro- and microvascular ED during acute hhcy induced by an oral methionine challenge in healthy subjects. Acute hhcy leads to a significant decrease in flow-mediated vasodilation of the brachial artery as determined by vascular ultrasound, indicative of macrovascular ED, as well as a decreased number of recruited nailfold capillaries during postischemic reactive hyperemia as determined by videomicroscopy, and to a decreased ratio of acetylcholine (endothelium-dependent) vs. sodium nitroprusside (endothelium-independent) iontophoresis induced skin perfusion as measured by laser doppler flowmetry, indicative of microvascular ED. Preliminary results show that pretreatment with AGE for six weeks diminishes the adverse effects of acute hhcy on endothelium-dependent brachial artery vasodilation and on acetylcholine-induced stimulation of skin perfusion. Whether or not this is accompanied by changes in biochemical parameters of ED is still under investigation. It is concluded that AGE may at least partly prevent a decrease in bioavailable NO during acute hhcy.

Bee Propolis

Date: May 12, 2005 05:14 PM
Author: Darrell Miller (dm@vitanetonline.com)
Subject: Bee Propolis

Propolis

Bees create propolis by collecting a resinous sap from trees and then mixing it with wax back at the hive. They use this material much the way people use caulk: to seal their homes. Chemically, propolis is exceedingly complex and contains a rich variety of potent terpenes and benzoic, caffeic, cinnamic,and phenolic acids. It's also high in flavonoids, which by themselves may account for many of the benefits attributed to propolis-and some researchers refer to propolis as a type of flavonoid.

One of the most significant medical journal articles described how the caffeic acids in propolis and honey might prevent colon cancer, which kills some 60,000 Americans each year. Chinthalapally V. Rao, Ph.D., of the American health Foundation, Valhalla, N.Y., reported in Cancer Research (Sept.15,1993; 53:1482-88) that these caffeic acids prevented the formation of precancerous tissue in rats after they were exposed to cancer-causing chemicals.

Most medical articles, however, still point to the value of propolis as a powerful, natural antibiotic. That doesn't mean eating propolis will let you throw away your antibiotics - only that you may not need them quite as often.

Why would bees need substances with broad antibacterial and antiviral properties? Any beekeeper will tell you the answer. Bees are very susceptible to bacterial and viral infections, which can destroy hives the way the bubonic plague ravaged Europe in the 17th century.

Two medical journal articles document the activity of propolis specifically against Staphylococcus aureus, the bacterium that causes dangerous and often deadly surgical infections, blood poisoning, and a type of pneumonia. Five to 10 percent of all patients hospitalized in the United States develop such infections, and S. aureus has become resistant to all but one pharmaceutical antibiotic.

In a Chinese study, researchers found that extracts of propolis - specifically, sinapic, isoferulic, and caffeic acids - inhibited the growth of S. aureus (Qiao Z, China Journal of Chinese Materi Medica, Aug. 1991;16:481-2). A European study reported that ethanol extracts from propolis had a "marked synergistic effect" on the anti-staph activity of two antibiotics, streptomycin and cloxacillin, and a moderate effect on several others (Krol W, Arzneimittel-Forschung, May 1993;43:607-9).

Another scientific investigation discovered that propolis inhibited the activity of several streptococcal bacteria species that cause dental caries.Japanese researchers reported that propolis-fed laboratory fats had far fewer caries than those given a regular diet. Propolis protected specifically against Streptococcus mutans and several other strep species (Ikeno K, Caries research, 1991;25:347-51). These strep species are closely related to the germ that causes strep throat.

Propolis works against bacteria in several ways. One study reported that it prevented bacterial cell division and also broke down bacterial walls and cytoplasm, which is how some prescription antibiotics work (Takaisi-KikuniNB, Planta Medica, June 1994;60:222-7).

Perhaps more remarkable is that propolis acts against viruses, which antibiotics do not. A number of medical journal reports have discussed the role of propolisin fighting upper respiratory infections, such as those caused by the common cold and influenza viruses (Focht J, Arzneimittel-Forschung, Aug. 1993;43:921-3). Other investigators have reported that the cinnamic acid extracts of propolis prevent viruses from reproducing, but they worked best when used during the entire infection (Serkedjieva J, Journal of Natural Products, March 1992;55:294-302).

Underpinning many of the benefits of propolis is that some of its components,like the flavonoids and ethanols, function as antioxidant free-radical scavengers. A study published in the Journal of Ethnopharmacology (Jan. 1994;21:9-13)noted that some of the antioxidant phenols in propolis functioned similarly to vitamin E. In another article, researchers described that propolis had anti-inflammatory properties and that it could also prevent blood clots(Drugs Under Experimental & Clinical Research, 1993; 19:197-203).
