Subject: Your Healthy Harvest

Your Healthy Harvest by Marjorie Flakowitz Energy Times, August 15, 2004

Once frowned on by conventional farmers, organic food has won respect from everyone concerned about the health of both the earth and the people who inhabit it.

Today, organic farming is considered one of the most rapidly growing areas of American agriculture. Organic foods sales topped $9 billion in 2002 and grew about 20%, up to almost $11 billion in 2003 (Organic Trade Association).

So when you buy organic, you join an expanding market that takes advantage of great-tasting, good-for-you food. Long ago, when the practice of farming was first devised, all farming was organic farming. So today's organic movement is bringing farming back to its roots.

But, safe to say, that is not what's motivating most consumers. A main reason for the popularity of organic food derives from the reassurance that organic foods, raised without artificial chemicals and pesticides, cut your exposure to toxic residues. A growing body of research shows organic food is richer in beneficial natural substances, too.

" Organic food and organic farming represent a philosophy that goes beyond just the quality of the food," says Steve Meyerowitz in The Organic Food Guide (Globe Pequot). "It strives to maintain the integrity of the entire food chain-plants, soil, air, water, animals and people. We are all part of the same ecosystem."

By eating organic, you eliminate pollution both from your body and the earth. Because our bodies are made of the animal and plant products we consume, our internal, physiological ecosystem and the earth's environment are inexorably enTwined.

Chilling Arctic Evidence

As evidence of this connection, consider what's happened in the Arctic. Researchers who have analyzed Arctic water, ice, snow, soil and plants have found that chemicals used in farming and industry in other parts of the world have traveled north and accumulated in alarming quantity. How and if these chemicals break down depends on sunlight and the amount of organic matter contained in Arctic waters (American Chemical Society, 9/11/03).

" Once pollutants enter the water column, their behavior is poorly understood-particularly the processes that govern their lifetime and concentrations," says Amanda Grannas, PhD, a researcher at Ohio State University. "Such pollutants are now being found in wildlife, from fish to seals to whales, and even in people living in the Arctic."

Dr. Grannas and others looked at the pesticides lindane and hexachlorobenzene (HCB), two chemicals that have migrated to Arctic waters. Lindane is used by American farmers to treat seeds before they are planted. HCB, banned in the US in 1984, is still used in other countries to protect wheat from fungus.

The scientists found that sunlight at the top of Arctic waterways can help break down some pesticides. At lower depths, however, cut off from the sun's rays, pesticides can remain largely intact. In this research, lindane proved to persist much more readily than HCB.

" Lindane is one of the most persistent of pollutants," warns Dr. Grannas. "This could be because it's photochemically inert, whereas pollutants like HCB degrade relatively quickly. The main message is that pollutants can behave quite differently. These pollutants already affect local ecosystems, and could have repercussions for human health."

Organics Means More Benefits

Researchers are also finding that organic produce contains larger quantities of beneficial natural chemicals. For instance, one study (Journal of Agriculture and Food Chemistry 2/26/03) showed that berries and corn grown organically can have almost 60% more polyphenolics. Polyphenolics are antioxidants plants use for protection against disease and which are good for humans. Researchers believe that when crops are grown conventionally, protected by pesticides and herbicides, they produce fewer of these substances. " This really opens the door to more research in this area," says Alyson Mitchell, PhD, assistant professor of food science at University of California at Davis, who led the research.

These scientists compared levels of total polyphenolics and vitamin C content in marionberries (a type of blackberry) and corn grown organically, sustainably or conventionally, and also looked at chemicals in strawberries grown either sustainably or conventionally. (Sustainable farming falls between the organic and conventional methods, and concentrates on farming that's self-sufficient-for example, feeding cows hay you've grown yourself, and then using the cows' manure to fertilize another crop.) They found that organic marionberries and corn had 50% to 58% more polyphenolics. The sustainably grown strawberries had 19% more polyphenolics. And all the organic produce contained more vitamin C.

Self-Defense for Plants

According to Dr. Mitchell, the organic crops contained the high levels of polyphenolics you'd expect to find in wild plants, suggesting that, on conventional farms, pesticides reduce the necessity for plants to make these protective, natural chemicals. " If an aphid is nibbling on a leaf, the plant produces phenolics to defend itself," she says. "[P]henolics guard the plant against these pests."

Pesticides kill insects like aphids and thereby reduce the antioxidants produced by the plant. " This helps explain why the level of antioxidants is so much higher in organically grown food," Mitchell says. "By synthetically protecting the produce from these pests, we decrease their need to produce antioxidants. It suggests that maybe we are doing something to our food inadvertently.

" We know [polyphenolics] are beneficial [to human health], but we don't know what types of polyphenolics are beneficial, or in what quantities," Dr. Mitchell notes. " Originally, the question was just really intriguing to me. I found that the higher level of antioxidants is enough to have a significant impact on health and nutrition, and it's definitely changed the way I think about my food."

Vitamin C in Oranges

Meanwhile, nutritional research on the vitamin C in oranges turns up similar results: organic oranges are richer in this antioxidant nutrient than conventionally grown oranges (Great Lakes Regional Meeting, American Chemical Society, 6/2/02).

The more common supermarket oranges are significantly larger than organically grown oranges, and they have a deeper orange color. Because of their larger size, "we were expecting twice as much vitamin C in the conventional oranges," says Theo Clark, PhD, chemistry professor at Truman State University in Kirksville, Missouri.

But when he isolated the chemicals in the oranges and further refined his search with nuclear magnetic resonance (NMR), spectroscopy demonstrated that organically grown oranges possess 30% more vitamin C than the conventionally grown fruits-even though they are only about half as large.

Dr. Clark isn't sure why organic oranges are richer in vitamin C, but he says, "...[W]e speculate that with conventional oranges, [farmers] use nitrogen fertilizers that cause an uptake of more water, so it sort of dilutes the orange. You get a great big orange but it is full of water and does not have as much nutritional value.

" However, we can only speculate. Other factors such as maturity, climate, processing factors, packaging and storage conditions require consideration." Along with analyzing oranges, Dr. Clark and his research team questioned about 70 people to measure their concept of the nutritional value of organic oranges. In this survey, 85% of the respondents thought that organic oranges have a higher nutritional content than conventionally grown fruit.

Dr. Clark's laboratory work shows that "they were right on." In Dr. Clark's view, these issues are important because consumers have a right to know the real nutritional content of organic produce, and the fact that analyses show that organic fruit has much more vitamin C validates the benefits of eating organic.

Defense Mechanism

Both plants and animals protect themselves from disease with many of the same chemicals. The natural substances that, in a farmer's field, defend vegetables from insects and microbes before they are harvested for your dinner go to work defending your body after you eat and digest them.

When you eat organic you bolster your health with more of these natural wonders. No wonder organic is becoming so popular!

Subject: Go Green - green foods may be the SWAT team that sets you free...

Go Green by Chrystle Fiedler Energy Times, December 4, 2003

If you feel like your busy life is holding your health hostage, green foods may be the SWAT team that sets you free. "Green foods are worth a king's ransom as far as your health is concerned," says Betty Kamen, PhD, author of Betty Kamen's 1,001 Health Secrets (Nutrition Encounter). "Green foods capture solar energy, using it to produce chlorophyll, which gives it its distinctive green color. Since we obtain our food by eating these plants or by eating the animals that eat these plants, this process is the source of human life."

"Green foods are renewal foods," says Ryan Bradley, ND, of the Bastyr Center for Natural Health in Kenmore, Washington. "They help to counteract the nutrient depletion caused by stress and by caffeine intake. They're nutrient dense, grounding, balancing, and soothing in their energetic nature."

Ideally, your meals should supply you with greens, but "...99.9% of the population doesn't get three to five [daily] servings of leafy green vegetables like kale, collard greens and spinach," says Jordan Rubin, NMD, PhD, CNC, author of Patient Heal Thyself (Freedom Press). Green foods can bridge that gap.

"Green foods have become popular because it's a convenient way to get your servings," says Dr. Rubin. "You get the equivalent of two large salads with one serving of powdered green food. It's nutrient dense and low calorie so it's a great addition to any diet. It satisfies the brain so you don't feel hungry."

"Everyone can benefit from green food supplementation," adds Dr. Kamen. "It's a concentrated supplier of everything that's good about vegetables."

Chlorophyll for Health

The key ingredient of green foods is chlorophyll, the green blood of plants. The benefits for humans from chlorophyll can be profound. A study of individuals at high risk of developing liver cancer because of their exposure to environmental toxins showed a 55% reduction in noxious compounds when these people supplemented their diets with a semi-synthetic chlorophyll derivative with properties similar to those of chlorophyll (Proc Natl Acad Sci USA 2001 Dec 4; 98(25):14601-6).

"This research supports the long-standing notion that chlorophyll, and green foods, can play a role in detoxification in the liver, and thus 'cleansing' the blood," says Dr. Bradley. "It's a good addition to any detox protocol. Test tube evidence also suggests that chlorophyll inhibits mutations in human cells."

Chlorophyll is antimicrobial and anti-inflammatory. It can help fight anemia, improve digestion and elimination, and act as a mild diuretic. It also helps friendly bacteria in the gut reproduce and thereby possibly boost immunity.

Green, Green Grasses

Fast-growing plants, such as wheat and barley cereal grasses, contain the most chlorophyll and the deepest green color.

"Wheat grass was one of the country's first multi-vitamins," says Dr. Rubin, who is also the author of Restoring Your Digestive Health (Twin Streams Health). "Certified organic cereal grasses pull a vast number of nutrients from the soil."

"The solar-powered factory in the leaves of the young grass plants is almost beyond comprehension," says Dr. Kamen. "Sprouted grains have exceptional nutritive value and high amounts of certain vitamins and minerals."

Spirulina Time

The blue-green microalgae spirulina is a chlorophyll powerhouse.

"Spirulina is high in protein, up to 65%, and the blue pigment of this blue-green algae, phycocyanin, has antioxidant, antiviral and antifungal properties," says Dr. Rubin.

Like other greens, spirulina can help you cut calories. "When you nourish the body and the brain with nutrient-dense and low-caloric food, it satisfies that impulse to keep eating." Spirulina is also high in B vitamins such as riboflavin, niacin and pantothenic acid, all commonly depleted nutrients. B vitamins are critical players in overall metabolism, and are vital to nerve and adrenal function.

Spirulina contains the minerals potassium and magnesium, plus iron. "It's been scientifically validated that [spirulina's iron is] comparable to the absorption from an egg," says Dr. Bradley. "It may benefit patients that are anemic. It's also a great choice for vegans who are looking for plant sources of iron."

In addition, the spirulina compounds called phycocyanins may control inflammation and lower the risk of cancer.

"Spirulina stimulates the part of the immune system [natural killer cells] responsible for our ability to fight off viruses and survey our tissues internally and detect and kill cancerous tissue," says Dr. Bradley.

Chlorella Benefits

Like spirulina, chlorella stimulates your natural killer cells to fight bacteria and viruses, and to strengthen your defenses.

"Chlorella is the richest food on the planet in chlorophyll," says Dr. Kamen. "It's also high in protein and rich in beta-carotene and minerals.

"One of the truly amazing facts about chlorella is its ability to oxygenate the blood," Dr. Kamen continues. "If your blood doesn't have enough oxygen, you can become listless and lethargic. Chlorella actually increases your hemoglobin, the oxygen transporter in your blood, so there is more oxygen present. It provides the necessary fuel for making healthy cells, and the result is renewed energy and vitality."

Both spirulina and chorella also contain omega-6 fatty acids that have anti-inflammatory benefits and can improve the behavior of your blood vessels. In addition, they provide vitamin B12.

Green Foods from the Sea

Seaweed and other sea vegetables like kelp offer a green foods bonanza. Seaweed is low in calories but, like spirulina, offers a wealth of nutrients.

"Most seaweed provides a rich supply of many essential nutrients, including protein, calcium, iodine and zinc," says Bradley Willcox, MD, co-author of The Okinawa Program (Potter). "Iodine is essential to the function of the thyroid gland, which needs it to make hormones that regulate your body's metabolism. Lignans, the cancer-fighting phytoestrogens have been found in high quantities in seaweed, mostly kelp, which could conceivably provide some protection against certain types of cancers."

Lower rates of breast cancer were reported in Japanese patients eating a diet high in kelp (Nutr Cancer 1983; 4:217-22). Kelp has also been shown to reduce DNA damage induced by several known carcinogens (Mutat Res 1993; 303:63-70).

Sea greens contain omega-3 fatty acids, fats that boost heart health. "Sea vegetables may prove to be a more sustainable source of omega-3 fatty acids than the dwindling fish populations," says Dr. Bradley.

To incorporate sea greens into your diet, start by putting them on your lettuce and tomatoes.

"Sea vegetables can make a great addition to salads," says Dr. Bradley. "They're high in nutrition and add flavor because of the sodium. They also add texture, giving salads more crunch."

Other ways to green up your diet:

* "Kelp comes packaged in three-foot-long dried strips and is prepared by cutting the long strips into smaller two- to three-inch strips and boiling them for about ten minutes. You remove the kelp, and then you can use the broth in soups, salads and other dishes. Kelp simmered with vegetables or tofu and served in miso soup is an Okinawan favorite," says Dr. Willcox.

* Wakame (one of Dr. Willcox's favorites), a type of kelp, has a taste and appearance that may remind Westerners of spinach lasagna.

* Nori seaweed can be used to wrap sushi and rice balls and also to season salads, soups and noodles.

"Seaweed tastes great and if used wisely, should not tip you into sodium overload," says Dr. Willcox.

Go for the Green

More and more people are realizing and enjoying the benefits of green foods. Dr. Bradley recommends keeping your green foods consumption simple. Add powdered greens, dried tablets and liquids to juice, mix them into smoothies or a protein shake, and sprinkle the powder on salads. Mixed in water, greens can be used as a morning tonic and help replace some of the nutrients like magnesium and B vitamins depleted by coffee and other caffeinated beverages, which act as diuretics.

"Incorporate a green drink into your diet once or twice a day," says Dr. Bradley. "It's the least expensive (health) insurance policy you can have."

Subject: The Joints Are Jumping

The Joints Are Jumping by Rachel Alexander Energy Times, October 8, 2003

It usually starts with a Twinge in your back or an ache in your knees: Knee stiffness, back pain and joint inflammation can signal the beginning of arthritis.

According to the US Food and Drug Administration, arthritis affects over 42 million Americans-that's 1 in every 3 adults-and costs the economy nearly $65 billion annually. But as common as arthritis is, it doesn't have to extract a high cost from your joints.

Who's At Risk?

Arthritis literally means an "inflammation of the joints" and can affect anyone-from small children to 80-year-olds. Some groups are more prone to certain types of arthritis; for instance, those over 40 are at greater risk for developing osteoarthritis, a degenerative condition of the joints.

According to Johns Hopkins Medical Institute, more than 50% of all individuals over the age of 40 have x-ray signs of osteoarthritis in weight-bearing joints (such as those in the knees and hips), and nearly half of those over 65 have measurable symptoms of arthritis. Osteoarthritis is often caused by overuse, age, excess weight or genetics, or by a combination of these factors.

Rheumatoid arthritis, on the other hand, is a disease of the immune system that affects the joints, which can make it harder to diagnose because early symptoms-fatigue, weakness, loss of appetite and low-grade fever-can mimic other chronic conditions.

Stiffness and pain may or may not accompany the initial symptoms of rheumatoid arthritis. However, joints eventually become inflamed and swollen. Although less common that osteoarthritis, rheumatoid arthritis affects more than 2 million Americans.

Covering Up the Signs

Treating arthritis can involve the use of both conventional and non-conventional therapies.

"In osteoarthritis specifically, conventional medicine has just been focused on covering up the symptoms," says Jason Theodosakis, MD, author of The Arthritis Cure (St. Martin's Press). "In the history of medicine, this approach has been considered primitive."

But Dr. Theodosakis points out that treatment often depends on the type of arthritis involved: "Rheumatoid arthritis patients should be taking prescription drugs that are known to prevent the disease from progressing. [Use] alternative medicine as an adjunct..."

Conventional therapies often involve the use of non-steroidal anti-inflammatory (NSAID) medicines, such as ibuprofen and naproxen. The chief drawback of NSAIDs is the toll these treatments extort from the gastrointestinal system.

In fact, a 2002 study conducted by researchers at the University of South Florida, Tampa, found that more than 15% of patients developed digestive problems after a five-week course of ibuprofen. In addition, ibuprofen may increase blood pressure.

Newer prescription NSAIDs called COX-2 inhibitors, which work by suppressing the body's inflammatory response, also carry risks of side effects ranging from diarrhea and fluid retention to liver damage and kidney problems. In addition, people with asthma or chronic allergies (including to aspirin) should not take these medicines.

Corticosteroids-another treatment option that has been used to lessen inflammation-can cause side effects such as increased appetite, mood changes and even immune system breakdown.

Natural Answers

A growing body of evidence shows that nutrients such as glucosamine and MSM, coupled with lifestyle changes, can help decrease or eliminate some of the aches and pains of arthritis. Glucosamine is a natural chemical that helps build joints. When the cartilage in joints deteriorates due to age or other factors, studies indicate that glucosamine provides the necessary building blocks for rebuilding and repairing this tissue.

In one investigation (Archives of Internal Medicine 2002; 162:2113-23), scientists discovered that glucosamine slowed the progression of osteoarthritis and improved symptoms for over 200 patients. Another study, conducted by researchers in the Netherlands, demonstrated that a combination of glucosamine and chondroitin holds promise for conditions such as spinal disc degeneration.

To date, several studies have confirmed glucosamine's ability to help the symptoms of arthritis, and the National Institutes of Health is currently supporting research to further study the benefits of glucosamine.

Other Joint Aids

MSM is often an adjunct therapy as it does not work directly on joints, but provides the raw materials, in this case sulfur, to help rebuild cartilage in the joint matrix. Studies indicate that sulfur has a protective effect and may interact with magnesium, an essential bone nutrient.

Traditionally, the herb horsetail (Equisetum arvense) has been used to supply silica, a mineral component of nails, bones and joints. Its support of these structures can help in the fight against arthritis.

As the body ages, it may lose much of its silica reserves. Resupplying much of this mineral may help support joints. In addition, experts believe, silica can help the body use calcium more effectively and support bone health.

Since rheumatoid arthritis is a systemic affliction, you should work with a trained health professional in treating it. Complementary care practitioners often use antioxidant nutrients, such as vitamins C and E, to reduce free radical damage, along with pantothenic acid (vitamin B5) to lessen morning stiffness.

A Joint Project

According to Dr. Theodosakis, exercise is the key to dealing with arthritis: "[Start with] an individualized exercise program that strengthens the joints without causing more damage...and an eating program to control your weight if you are currently overweight." To limit the effects of arthritis, you should quit smoking, since smoking generates free radicals that can harm the tissues which make up joints. In addition, a strict vegan diet may help alleviate some of the pains of rheumatoid arthritis.

Dr. Theodosakis also recommends looking for hidden causes of symptoms, such as food allergies, that may contribute to arthritis.

Heat helps ease arthritis pain and encourages both blood flow and tissue repair. A plain, old-fashioned hot water bottle works quite well. Or you can use one of the newer heat-generating wraps, which are thin enough to be worn under clothing and don't have to be constantly reheated.

You can't always avoid arthritis, especially as you get older. But you don't have to let it get the better of you.

Subject: Basics of the Immune System

Basics of the Immune System

by Leonid G. Ber, MD Energy Times, September 1, 1998

In a world filled with pathogens and microbes, good health and resistance to disease is no accident. It requires a vigorous and vigilant immune system. The immune system should be viewed as an internal security force that is constantly checking the identity of everything entering and already existing in the body. A cell or substance may be recognized as "non-self" and a potential enemy if it does not have the right molecular make-up. A cell displaying molecules produced according to a different blueprint than the body's own code may be recognized as foreign. To eliminate alien material that may harm the body, the immune system must take swift action.

Recognizing entities that originate outside the self forms the key to overall immune system response. This key is carried in the body by cells called macrophages (ma-kro-fajs), a name derived from a Greek term meaning "big eater." Macrophages eat or engulf foreign cells and molecules. When a macrophage encounters something that it distinguishes as being "non-self" or abnormal, it can attack the enemy with a series of assault weapons, including free-radicals (reactive substances) and enzymes, that dissolve and weaken the intruder. In fact, an enzyme produced by macrophages called lysozyme is recognized as one of nature's most powerful anti-infective agents. These chemical defenses, along with engulfment and complete digestion by macrophages, can effectively stymie invasion by disease-causing pathogens.

Disease Invasion

Harmful invasion can originate in the body's own cells as well as begin from outside sources. While we are constantly exposed to bacteria, viruses, fungal cells and parasites, destructive cancerous growths often start within the body.

Every day, thousands of the body's cells mutate into possible cancers. Under most circumstances, the immune system keeps these cells under control. But when the immune "security" system slips up, these harmful growths multiply unrecognized.

Getting Specific

The initial immune response that recognizes invaders is called a "non-specific defense mechanism" since this immune response is generally the same toward all invaders. This counter-attack entails battling every invader pretty much identically: a macrophage can engage, dissolve, weaken, engulf, digest, eliminate. However, if, despite the initial immune efforts, the problem persists, a macrophage can tag an invader and "introduce" it to the rest of the immune system, thus recruiting more specialized types of immune cells to enter the battle. This tagging function endows macrophages with the name "antigen-presenting cells." (Antigens are substances that can provoke specific responses by the immune system.)

Most antigens are proteins. Proteins are relatively large molecules made of smaller units called amino acids. The specific geometric organization of amino acids is what conveys uniqueness to each protein. (Your genetic code forms a blueprint for the production of your own, individual proteins.) Protein molecules produced by one human being can act as an antigen for another human being. That's why organs transplanted from one person to another can be rejected by the immune system. Unless organs are transplanted from one identical Twin to another (who share the genetic blueprint for protein creation), doctors must use immune-suppressing drugs to curtail organ rejection. At the same time as these medicines prevent transplant rejection, they also make people more susceptible to infectious diseases and cancer.

Specialized Immunity

After one set of immune cells chemically tags antigens (invaders) for recognition, other highly specialized parts of the immune system go into action: Cells called T cells or T lymphocytes acknowledge the invaders and can take the further action (second line of defense) that is necessary to render them harmless.

T cells get their name from the thymus (an organ located behind the sternum) where they originate. The thymus, most active when we're young, usually shrinks and apparently slows or shuts down its activity about the age of forty.

A wide variety of T cells inhabit lymph nodes (soft, usually round, pea- or nut-sized organs) and other body areas. For instance, natural killer cells, as their name implies, are a particularly aggressive type of T cell. Another type of T cell is called T helper (a cell that supports development of immune response). T suppressors halt immune response when infection ends.

In order to make all these different cells work in concert, cytokines or messenger molecules are produced that facilitate constant communications between all the parts of the immune system.

The B Team

Other organs of the immune system include:

*bone marrow: a powerful cell producing organ where the majority of immune cells are born;

*spleen: an abdominal organ that forms a reservoir for the production of immune cells.

Lymph nodes oversee particular segments of the body where they collect and recycle tissue fluids. Like an early warning system, lymph nodes react when an invader is detected in the part of the body that it controls.

Yet another step in the so-called immune cascade entails action by lymphocytes, called B cells, which originate in the bone marrow. These cells produce antibodies which are immune proteins (immunglobulins) that attack specific antigens.

While traveling in the blood, an antibody can bind to an antigen, curtailing its harmful action. This bound up molecule forms a complex easily recognized by scavenging macrophages which make a quick meal out of the unlucky invader.

After enemy cells are removed from the body, knowledge of this victory resides in the immunological memory prolonging your resistance toward specific disease pathogens indefinitely. That's why someone who has recovered from a disease like the measles may be impervious to reinfection.

Rules for Optimum Immunity

Even though the immune system consists of a complex team of hard-working cells, enhancing your immunity is relatively easy:

Maintain a healthy lifestyle. Avoid continuous stress and negative emotions or cope with them through exercise or meditation. Consistent, moderate exercise can boost the immune system. Massage can also help although extreme care must be taken when inflammation or disease is already present.

Sleep 7-8 hours a day. Sleep allows the body to recover and rebuild. Protein synthesis, vital for a healthy immune system, increases during the night.

Stick to a healthy diet. Your immune system consists of trillions of cells. Consequently, nutrients important for cell health boost the immune system. A balanced low-calorie diet rich in complex carbohydrates, "good" fats (including fish oils, olive oil and flaxseed oil) along with vitamins, minerals and phytonutrient antioxidants from fresh fruits and vegetables can fortify immune cells. Plus, drinking plenty of water helps improve circulation of lymph fluid.

These recommendations are not hard to meet once they become a part of your daily routine. However, extra immune security may be necessary during flu season, while traveling long distances (airplanes are notorious sources of pathogens) or when working extensive hours in front of a computer screen. In addition, exposure to x-rays, immunosuppressive chemicals, ultraviolet radiation (the sun) or simply aging may give your immune cells extra burdens.

Your "specific" immune system does not respond immediately to the challenge of invasion by an infectious organism. Instead, it may require about 2 weeks for an effective reaction after antigen recognition and alerting T cells. During this period, the macrophages' non-specific defense assumes a crucial role in keeping infection in check.

Enhanced activity by macrophages is especially important for recognizing and destroying cancer cells. The most dangerous cancers are those that can mimic normal cells and avoid the immune system's wrath. Few substances can activate macrophage function in the body (aloe vera contains substances that contribute to this process). The most powerful macrophage activator recognized by the scientific community is a sugar-like substance called beta-1,3-D-glucan. Beta-glucan, extracted from the cell walls of common Baker's yeast, when taken in certain small amounts, can prevent infection by making macrophages more active in recognizing and attacking infectious bacteria, fungi and certain viruses.

This kind of activation can encourage macrophages to attack previously unrecognized tumor cells. As a result, tumors may be eradicated as the immune system mobilizes and produces what may be known as "spontaneous healing."

Hungry Macrophages

When a macrophage works overtime fighting disease, its demand for nutrients and energy increases dramatically. Vitamin C, known for its immune supporting function, seems to be especially important for maintaining fully active macrophages. Vitamin C collects in macrophages, often reaching forty times the concentration found in surrounding blood. What are conventionally considered normal amounts of vitamin C in the body may be insufficient to keep macrophages well supplied with this antioxidant. Therefore, extra amounts of vitamin C can keep the immune system in fighting trim.

Scientists are only now beginning to uncover the secrets of the highly organized immune system. One thing's certain: The immunity security team depends on proper lifestyle, nutrition and supplements to maintain the critical defenses necessary for good health.

Dr. Ber received his doctorate in internal medicine from the Yaroslavle, State Medical Institute in Yaroslavle, Russia.

Subject: Saw Palmetto Ectract - Man's Best Friend

Saw Palmetto Extract

The complex and fragile human reproductive system is highly sensitive to imbalances. For American men, prostate dysfunction has become a common issue this decade – and aging is not the only culprit. The chemical environment created by industrialized nations is a major detriment to the health of the prostate gland. Fortunately, help comes from the experience of Native Americans who relied on the berries of the Saw Palmetto tree for strength and vitality throughout their lives. Source Naturals SAW PALMETTO EXTRACT is a highly concentrated form of this renowned berry. Developed for maximum potency and convenience, SAW PALMETTO EXTRACT empowers men to defend themselves against the Twin onslaught of time and technology.

Prostate Dysfunction

Recent statistics have revealed some alarming findings – dysfunction of the prostate gland is now becoming more and more common for men in the industrialized nations. No longer is aging alone to blame. Chemical toxins in our food and environment are contributing to the rising incidence of diminished prostate function. By their forties, many men experience a hormonal shift that increases the size of the prostate gland. If the prostate cells begin to over-produce, neighboring organs can be adversely affected. Another factor causing prostate dysfunction is the host of synthetic chemical compounds that have entered into our environment and into our bodies.

Saw palmetto supplements offer support to the prostate gland by offsetting the repercussions of both the natural hormonal shift and the environmental challenge. Recent clinical tests in Europe have demonstrated the benefits of 320 mg of saw palmetto extract as a daily dietary supplement. Source Naturals is committed to bringing the latest nutritional research to the marketplace – providing people with natural solutions to critical health issues. Our SAW PALMETTO EXTRACT contains the highest quality saw palmetto available. We offer it in two potencies: 320 mg and 160 mg.

Hormones and the Prostate Gland

The prostate is a walnut-sized gland that surrounds the urethra in males. The prostate secretes the seminal fluid and, through a series of contractions, allows the release of semen from the body. Beginning in their forties, men experience a change in hormone levels that may increase the prostate’s size to that of a plum, or larger. This growth is related to a significant increase inside the prostate of di-hydrotestosterone (DHT), a potent male hormone. As men age, their prostate loses its ability to break down and remove DHT. Hormones in the environment also play a role in our health. Many commercially farmed animals are treated with synthetic hormones to increase food production, and these hormones remain in the fatty tissues of meat. When humans consume this meat, these artificial hormones gravitate to the fatty tissues and organs – especially the prostate gland. The formation of DHT is further increased by certain pesticides, synthetic organochlorines, and other “endocrine disrupters” that block or mimic natural hormones. These synthetic hormones are believed to contribute to lower sperm counts and prostate dysfunction.

Saw Palmetto – Prostate Friendly

For centuries, berries of a small palm tree called Saw Palmetto (Serenoa repens) were used as food by Native Americans living along the southern Atlantic coast of North America. Saw palmetto is well-known for its benefits to men and has been the subject of numerous studies. Its berries are rich in sterols and fatty acids that naturally migrate to the prostate. Here they help prevent the conversion of testosterone to DHT, and accelerate the breakdown and elimination of DHT from prostate tissues. The natural phytoestrogens in saw palmetto berries also can block artificial estrogen-like compounds from accumulating in prostate tissue. In Europe, saw palmetto extract has been studied in six double-blind clinical tests. Men who were given saw palmetto extract showed consistent and statistically significant results. Source Naturals SAW PALMETTO EXTRACT is standardized to 85-95% fatty acids and sterols. Whether you prefer a single 320 mg softgel or two 160 mg softgels, Source Naturals SAW PALMETTO EXTRACT provides the equivalent amount of saw palmetto used in these recent European studies.

Tried and True Protection Source Naturals SAW PALMETTO EXTRACT is the first line of defense in a men’s health program. The benefits of Saw Palmetto have been time-tested by traditional cultures and studied by modern clinical research. To maintain vital prostate function, SAW PALMETTO EXTRACT is the best step a man can take.

Lutein

One of the more surprising discoveries of modern nutritional science is that the very pigments which give brilliant color to our fruits and vegetables are powerful nutrients which can protect us from the rigors of time and environment. Lutein is one of the most recent discoveries in this field. In our diets, it’s found most abundantly in dark green leafy vegetables such as spinach, collards and kale. Like beta-carotene, lutein is a powerful antioxidant which studies show can contribute to the protection of cells. But the most promising application of lutein may be its beneficial influence on the eyes, particularly in regard to macular degeneration. Source Naturals LUTEIN is a concentrated source of this important natural nutrient.

Like the beta-carotene that makes carrots orange and the lycopene that makes tomatoes red, lutein is a carotenoid. It is the pigment that makes corn yellow, and gives marigolds their brilliant golden color. One of the most interesting aspects of the way carotenoids interact with the human body – beyond their broad spectrum antioxidant activity – is their tendency to be “organ specific.” Different carotenoids have an affinity for different organs in the body. In the case of lutein, it is found concentrated in the structure of our eyes.

Vision and Macular Health

The process of vision involves light being focused through the lens and onto the retina, the paper-thin tissue lining the back of the eyeball. The central portion of the retina, called the macula, receives the most light. Its millions of cells produce the sharp vision needed to read and see objects clearly. With age, tiny blood vessels grow over this area, causing a gradual distortion and loss of vision. This degeneration of the macular region of the retina is the leading cause of irreversible visual impairment in the USA today. It affects almost 20% of people past the age of 65. Research has shown that these people have lower than normal amounts of macular pigment, which suggests the protective role played by these pigments. In fact, the latest research suggests that low levels of macular pigment is a cause, rather than a result, of macular deterioration.

Lutein – The Eyes Have It

Lutein and another carotenoid called zeaxanthin are the most dominant pigments in the macular region of the retina. (Source Naturals LUTEIN contains 5-7% zeaxanthin.) Their antioxidant properties help maintain the integrity of the blood vessels that supply the macular region of the retina: providing protection from photo-oxidation, the result of light striking the fatty acids in the retina. It seems that lutein is particularly active against the blue part of the spectrum, which can be the most damaging to our eyes. One study using lutein supplements resulted in a 15% increase in macular pigment levels after 72 days. In another study, people who consumed the equivalent of 6 mg of lutein per day were 40% less likely to experience macular problems. Another study using sets of identical Twins demonstrated that macular lutein concentrations were related to dietary lutein. After consumption, lutein is found in significant quantities in blood serum, suggesting high bioavailability.

Our Connection with Plants

In this era of biochemistry, we’re rediscovering our vital connection with plant life. Although research into phytonutrients is relatively new, many plant compounds are being found in significant concentrations in the human body. Their presence in our blood serum, organs, and mothers’ milk suggests they play an important role in our body chemistry, and perhaps explains why we’ve appreciated them as foods throughout history. Like many carotenoids, lutein has evolved as an integral part of human biochemistry, with many benefits to our well-being. Since mammals cannot synthesize it, lutein must be obtained from the diet. Source Naturals LUTEIN is extracted from specially grown marigold flowers high in Lutein, and purified by an exclusive patented process. So the next time you bathe your eyes in a golden bouquet of marigolds, remember their beauty really is in the eye of the beholder.
