fish oilBefore you can compare flaxseed oil and fish oil

It is first important to understand the differences between the two oils. Extracted from the dried seeds of the plant rips linen, flax seed oil is clean and almost yellow. The oil is obtained by a cold method or by solvent extraction. Flaxseed oil contains acid lineolic, a particular form of omega-3 fatty acids. Fish Oil is extracted from the tissues of fatty fish containing EPA, Docohsahexanoic acid (DHA) and Eicosanoids.

Benefits of compare flaxseed oil and fish oil

Some of the health benefits are reducing inflammation. For comparison, it is essential to analyze the benefits of both oils. Two omega-3 fatty acids, EPA and DHA in this oil and are a great help in creating hormone-like substance that reduces inflammation and blood pressure. They have also been shown to reduce triglycerides and the accumulation of plaque in the arteries.Omega-3 oils promote the secretion of serotonin. Serotonin is a chemical anti-depressant produced by the body and thus reduces or mitigates the effects of depression. Fish oil is often used in the treatment of patients with HIV / AIDS, and has proven to be helpful in lowering triglyceride levels in the body that build up after prolonged use of antiretroviral drugs. This is extremely useful because it can reduce the risk of a patient for coronary artery disease. In addition to providing relief from chronic inflammation, they is also useful for those suffering from joint pain, such as rheumatoid arthritis. The EPA has also found that fish oil helps protect the skin from photo damage. Photo damage is known to cause permanent skin wrinkles and skin damage. In addition, some studies have shown that they may prevent schizophrenia, with minimal side effects. Mothers who take fish oil during pregnancy often bear children with enhanced brain function as well as children with higher IQs. They are also less prone to cognitive problems. And the effects of postpartum depression seem to lessen with the regular intake of fish oil.The fish oil supplements have even more benefits, including lower risk of macular degeneration in the aging process. And studies have shown that with weight training significant reduced pain is present in the bodybuilders who regularly consumed fish oil. Other benefits are providing relief for digestive diseases..

Subject: Is Pycnogenol a Good Antioxidant?

Pycnogenol And Your Health

Pycnogenol is the latest innovation in the antioxidant supplement industry. It makes use of oligomeric proanthocyanidins, select bioflavonoids, and organic acids that have been well investigated in a span of more than 30 years. As a trademarked product, it has been cited in more than 230 published works and systematic reviews that came into the conclusion that it is safe and effective. In fact, it is now an ingredient in over 300 health products.

Pinus pinaster is an indigenous plant species of western Mediterranean from which the patented pycnogenol is extracted from. It is most populous in southwestern France, but it can also be found in large numbers in Portugal, Spain, Italy, and Morocco. Unlike new ingredients in some dietary supplements, pycnogenol is all-natural and completely derived from the Maritime Pine, which may well be known in the now-obsolete scientific name Pinus maritima.

Neutralizes Reactive Oxygen Species Fast

Antioxidants work on the principle of replenishing the antioxidant reserves of each cell especially at times when our body is most susceptible to physical fatigue. Radical chemistry has taught us that reactive oxygen species, or ROS, are natural by-products of oxygen metabolism. There is nothing we can do to inhibit their releases, but our body does have a mechanism to neutralize them. Free radicals are one of the best known ROS and they are particularly reactive, causing a damaging chain reaction called oxidative stress.

What makes pycnogenol different from other antioxidant supplements? It is the fastest-acting antioxidant out there with an absorption rate of only 20 minutes. In contrast with other known antioxidants, such as vitamin C and vitamin E, pycnogenol is believed to readily cross the blood-brain barrier, expanding its uses in the central nervous system. This is the reason why it has been suggested to be of value in treatment of known disorders of the nervous system. More importantly, it works up to a record-high 72 hours before it gets excreted by the body.

Fight Inflammation and Cardiovascular Disease With Pycnogenol

Displays Potent Anti-Inflammatory Activities

There have been numerous citations that pycnogenol is an effective inhibitor of inflammation intermediaries. It is postulated that it influences the productions and releases of Eicosanoids that govern inflammatory responses. It has associated with the treatment of osteoarthritis, and preliminary results are encouraging. Also, it is believed that pycnogenol interferes with the effects of histamine via its receptors, and acts on mast cells responsible for mediator release. This is the reason why it is widely accepted as a viable treatment option for asthma, multiple sclerosis, allergic rhinitis, acute dermatitis, atopic eczema, and other skin conditions.

Contributes to Overall Circulatory Health

Pycnogenol is one of the antioxidants under scrutiny for its medicinal potential in the prevention of major diseases that afflict the circulatory and cardiovascular systems. For one, it has been observed to significantly lower systolic blood pressure, making it an effective therapy for hypertension. It has shown to alleviate chronic venous insufficiency and remove varicose veins. Moreover, regular supplementation of pycnogenol appears to improve performance in endurance athletes.

Pycnogenol is an excellent herb to add to anybodies diet. Give Pycnogenol a try today!

Holy Basil And Cholesterol, Inflammation, and more

Ocimum tenuiflorum, known as Holy Basil in the vernacular, is an herbal plant indigenous to South Asia, where it is called Tulsi. It is widely distributed across the subcontinent of India and surrounding countries and is primarily cultivated for its age-old medicinal benefits in addition to its religious significance to Vaishnavite practices of Hinduism. It has earned popularity as a health tonic over the centuries, and recent studies have supported its positive effects on human health. Today it is often associated with lowering cholesterol and glucose, acting as an antioxidant, and regulating inflammatory intermediaries.holy basil plant

Counteracts Stress Factors

The juice of holy basil has long been reputed to display adaptogenic properties. There have been countless accounts of its effectiveness in combating stress. In fact, the most compelling of all anecdotal evidence has something to do with its ability to create a feeling of wellness right after ingestion, the same tonic benefits attributed to ginseng. To date studies point to its homeostatic effects on the stress hormone cortisol, creating homeostatic effects on its metabolites and their interactions with compounds released in response to stress.

Neutralizes Free Radicals

Holy basil has been observed to show antioxidant activities, and this is one of its mechanisms in allaying symptoms brought on by fatigue. Free radicals are released by the body to dispose of pathogens, but are in turn disposed of by endogenous antioxidants. Oxidative stress ensues when there is an imbalance between the production of free radicals and the ability of the body to neutralize them. The polyphenols found in holy basil helps the body quench excesses of free radicals.

Lowers Bad Cholesterol

There has been a growing body of literature devoted to the lipid-lowering properties of holy basil. The phytochemicals found in holy basil have been cited to affect the metabolic pathway that produces very-low-density lipoproteins, which is a precursor to low-density lipoproteins, or bad cholesterol, and bring about an increase in high-density lipoproteins, dubbed good cholesterol. Also, it has been associated to the overall decrease of lipids present in the bloodstream, notably free fatty acids.

Reduces Blood Glucose

One of the earliest observations on the health effects of holy basil is its properties that counter the progression of diabetes. It has been reported many times to have helped patients of type 2 diabetes mellitus, which results from the compromised ability of cells to respond to the hormone insulin. The use of holy basil extracts has yielded promising results on promoting the glucose uptake of cells, and, of course, the consequent decrease in glucose present in the blood.

Influences Inflammation

Holy basil has been extensively studied for its anti-inflammatory benefits. The most recent research has pointed out that organic compounds found in holy basil may inhibit the enzyme called COX-2, which facilitates the synthesis of inflammatory mediators. Eicosanoids are endogenous substances produced by local tissues during inflammation, and a special group called prostanoids is responsible for the pain tied to inflammation. By targeting COX-2, holy basil greatly aids against inflammatory diseases such as arthritis.

What is stopping you from giving holy basil a try today?

How Does Cherry Fruit Extract Help with Gout?

Subject: How Does Cherry Fruit Extract Help with Gout?

Cherry fruit extracts contain the micronutrients and phytochemicals found in cherries. They are available as supplements widely touted to display antioxidant and anti-inflammatory properties. Cherries, the fruits, are in fact very high in anthocyanins, which have a long association with the prevention of inflammation, even including the type that results in most known cardiovascular diseases. Also, research on anthocyanins in connection with its chemopreventative potential has yielded the most reliable public data. Individuals suffering from gout will definitely benefit from cherry fruit extracts as supported by an abundance of reports and anecdotal evidence concerning its efficacy.

Stabilizes Metabolism of Purine Nucleotides

The development of gout is greatly attributable to an anomaly in the metabolism processes involving purine nucleotides. A class of organic compounds classified as purines is necessary for life and present in many chemical reactions. They are a major component of ATP, the primary energy of cells, and several nucleotide bases of DNA and RNA are purines. The problem lies in its final metabolic product, uric acid, which at high levels condense into urate crystals that are deposited in tendons and ligaments, as is the case with gout and tophus. Cherry fruit extracts bring about twofold effects. First, they stabilize purine metabolites, notably uric acid, and, second, they facilitate the effective excretion of uric acid. If you consume a lot of foods high in purines such as animal products, especially beef, pork, and seafood, taking cherry fruit extracts will make sure that the uric acid they produce gets out of your system.

Affects Releases of Inflammatory Mediators

While high levels of uric acid is the causation of gout attacks, the painful inflammation that ensues is triggered by an entirely different group of endogenous compounds in the employ of the immune system. Eicosanoids have long been identified to precipitate pain not only during gout attacks, but in all inflammatory responses of the human body. These compounds are released locally by the cells around the joints containing urate deposits in an attempt to fight off the degenerative effects of uric acid on the surrounding tissues. They deal with the joints the same way they get rid of pathogens during infections, bringing on the redness, swelling, and pain characteristic of gout. A group of bioflavonoids called anthocyanins that are known to interfere with the releases of Eicosanoids are abundant in cherries, and intake of cherry fruit extracts deliver these flavonoids into the region of pain.

Normalizes Acidic Digestive Environments

Cherries belong to the group of foods that are alkaline forming. With gout thriving in an acidic setting, it is just prudent to carefully reassess your diet and cut down on foods high in purines. Not surprisingly, your doctor may tell you to minimize consumptions of meat products especially if you suffer from recurrent gout attacks. Cherry fruit extracts rebalances the pH level of your gastrointestinal tract, and supplementation will keep your body in an alkaline state in the long run, protecting you not only against gout but also against the aging process.

If you suffer from gout or other uric acid buildup disease, give cherry fruit extract a try today!

Can Astragalus Help Boost the Immune System?

Subject: Can Astragalus Help Boost the Immune System?

Astragalus

What we refer to as the herbal astragalus is actually a large number of plant species in the family Fabaceae, the same group of shrubs that we commonly identify as peas, beans, or legumes. Many of these species have been utilized in folk medicine of different communities all over the world, but the majority of herbal extracts made available as nutritional supplements today come from Astragalus propinquus, or Astragalus membranaceus.

Astragalus may be best known for its touted modulating effects to the immune system largely owing to the fact that it has enjoyed a very long history as a health tonic both in the East and the West. It is an important ingredient in Traditional Chinese Medicine, valued for its reinvigorating effects to what they call defensive energy of life. It is known by the name of Huang Qi in China, where most of the recent studies on this herb take place.

Regulates Interferon Releases

There are a number of studies that link astragalus to HIV in that it is purported to combat replication of viruses and inhibit growth of pathogenic microbes. To be more specific, it is believed to have an influence on the production of proteins called interferon, or IFNs. A type of white blood cell in the employ of the immune system called lymphocytes release interferon whenever the body detects the presence of viruses, bacteria, parasites, or even tumors. In addition, IFNs activate natural killer cells, which target cells infected with viruses and tissues afflicted with tumor, and program them to die.

Stimulates the Healing Process

It is also postulated that astragalus has an augmenting effect on the healing process by interfering with inflammatory agents. There are organic compounds called Eicosanoids that are released by the body in larger amounts to facilitate healing of wounds or infections through the process of inflammation. These compounds work hand in hand with the immune system in removing the pathogens that cause infections and initiate the reversal of damages done by these pathogens. If inflammation takes place longer than it is supposed to, the area affected will have to deal with prolonged pain, redness, and swelling. Astragalus works on the principle of maintaining healthy releases of Eicosanoids, the reason why it is used as a treatment for arthritis, dermatitis, asthma, and other autoimmune diseases.

Produces Homeostatic Effects

Astragalus has shown to be involved in many metabolic processes, maintaining stability of organic compounds from the foods we eat that reach the circulation. There have been mentions that it is particularly good for the lungs, adrenal glands, and alimentary canal by improving their functions and acting as a buffer to any unwanted debris that may attack the cells that make up these organs.

Be reminded that astragalus has been associated with a long list of health benefits, but none of these have yielded strong scientific support. It is safe to assume that testimonials are influenced by anecdotal evidence and initial results of studies that are yet to be concluded.

Inflammation is a normal part of the body’s defense against pathogens. The increase in body temperature, flood of toxic free radicals and inflammation-signaling proteins, and release of killer macrophage cells are the main signs of an inflammatory event that is the body’s long-established means of defending against a clear and present danger. This adaptive response can now become a cause for debilitating disease. It is even thought that the aging process may be linked to the very defense mechanism that keeps us healthy when we are young. As we grow older, our ability to regulate inflammation begins to diminish. Instead of protecting us, inflammation becomes silent and systemic, allowing degenerative disease to take root. The symptoms of silent inflammation are extremely different from acute inflammation of redness, heat, swelling, and pain, and can lie undetected until it has been around for far too long.

Silent inflammation causes the body to turn on itself, as its immune system begins attacking its own organs. Over time, inflammatory cytokines such as C-reactive protein, interleukin-6, and inflammation producing Eicosanoids like prostaglandin E-2 and leukotrienes B-4, start to destroy tissue all over the body. In response to this attack, the body produces even more inflammatory cytokines and free radicals, which creates a self-perpetuating cycle. Silent inflammation damages arteries, destroys nerve cells and organs, compromises the immune system, and promotes cancerous growths. Despite how well they feel today, those with silent inflammation are on a fast track toward degenerative disease. On the good side, preventative measures that are taken today to reduce inflammation can prevent degenerative diseases like cardiovascular heart disease, cancer, diabetes, and Alzheimer’s tomorrow.

When there are equal numbers of good and bad Eicosanoids, a state of wellness is able to prevail within the body. However, when they become chronically unbalanced, many problems result. This balance is, interestingly, highly dependant upon the level of insulin that is found in the body. High insulin levels, whether they are induced by sugar overload, the onset of insulin resistance, or the hormonal effects of excess fat, set the stage for systematic inflammation. As insulin levels climb, oxidative stress increases dramatically, causing the production of inflammatory cytokines. Along with being too high in refined sugar, the average North American diet is filled with inflammation-promoting fats and scarce in inflammation-reducing omega-3 fats; the consequence of this chronic fatty acid imbalance in an increase in systemic inflammation.

As inflammation rises, so does the production of cortisol, which is produced in the adrenal glands and is intricately involved in the body’s response to stress. In an attempt to reduce inflammation, cortisol increases blood pressure, elevates blood-sugar levels, and suppresses the immune system. This means that systemic inflammation produces chronically elevated levels of cortisol, which then place a heavy physiological burden on all organs, causing a dramatic increase on the risk of degenerative disease.

Fortunately, changing the balance within the body to favor the production of anti-inflammatory Eicosanoids can be achieved through a conscious dietary change. By simply increasing your dietary intake of fatty fish, eating raw nuts and grains rich in healthy fats, and supplementing with a high-quality cold-pressed fish oil or flaxseed oil, and concurrently decreasing your intake of red meats, eggs, high-glycemic foods, and foods high in saturated fats, chronic inflammation can be reduced greatly. Vitamin supplements can boost ones antioxidant intake and help fight inflammation as well. Quality vitamins are available at your local or internet health food store.

Subject: DHA

DHA is a fatty acid that is essential for many body processes and structures. Fatty acids are the building blocks that create lipids, which are important nutrients that make up 25 to 45 percent of total body energy for most of those who are living in industrialized countries. The majority of dietary fatty acids are made from dairy products, meat, margarine, and vegetable oils.

Lipids are important because they store and transport energy from one part of the body to another and they also insulate and mechanically protect certain parts of the body. Any fat that is eaten is converted by the body into fatty acids, where it is then burned for energy, stored, or synthesized into other acids which are called prostaglandins. Some fatty acids are also vital structural components of cell membranes. DHA is part of a special class of highly concentrated, long-chained, polyunsaturated fatty acids called omega-3 fatty acids. Omega-3 fatty acids are looked at as one of the most fundamental molecules in the structure and activity of the membranes of all cells. They have a huge influence on the production of cellular regulatory compounds which are known as Eicosanoids. They also are highly specialized in their function in neurological tissues, especially the retina of the eye. It is also very likely that omega-3s have specific and beneficial effects on the heart muscle, while they also influence the production of substances that control immune responses.

Fatty acids are short-chained, medium-chained, or long chained. Short-chain fatty acids are water-soluble and absorbed directly from the intestine into the bloodstream. They are generally used for immediate energy and can be found most abundantly in dairy products. Long-chained fatty acids are more emphasized when it comes to health concerns as they are stored in cell membranes and have a huge affect on membrane protein function. Their behavior in tissue membrane is what makes them greatly influential in health.

Besides the length of the chain, fatty acids are also described by their saturation. Saturation means how many hydrogen atoms the fatty acid carries. Fatty acids that carry as many hydrogen atoms as they can are called saturated fatty acids, while those that lose a pair of hydrogen atoms become unsaturated. This loss of hydrogen atoms creates a double bond between the two carbon atoms on either side of the missing hydrogen atoms. Those fatty acids that have one double bond are called monounsaturated fatty acids, while those with two or more double bonds are called polyunsaturated fatty acids. Most omega-3 fatty acids are highly unsaturated and have five or more double bonds.

EPA and alpha-linolenic acid are most commonly found in plant sources. DHA and EPA are made in phytoplankton, which is consumed by fish, mollusks, and crustaceans. The above reason is why these two essential fatty acids are found mainly in the aquatic food chain. LNA and EPA cannot substitute for DHA in all metabolic functions, even though DHA and EPA are more able to cover for each other in certain metabolic functions. It has been found that LNA is less effective than EPA which is less effective than DHA in enriching tissues, meaning that food sources such as vegetables and seed oils are not as good of sources than sea foods or other foods that are enriched with DHA and EPA. DHA in itself provides most of the health benefits displayed in research, to take essential oils that contain no DHA would limit the health benefits discussed above and from other sources.

The Healing Power Of Borage Oil’s GLA
TopPreviousNext

Date: November 13, 2007 10:22 AM
Author: Darrell Miller (dm@vitanetonline.com)
Subject: The Healing Power Of Borage Oil’s GLA

Borage is otherwise called the starflower, and the borage oil extracted from its seeds is very rich in GLA, gamma linolenic acid, a polyunsaturated fatty acid also obtainable from evening primrose oil. Borage, however, is richer in GLA, and is therefore a more economical source that the evening primrose.

A shrub, frequently seen in gardens, borage has historically been used as a salad food, and also in soups, and borage honey is prized in many quarters. Now, however, its main use is for the GLA extracted from the seed, which provides a higher yield of GLA than any other source. Borage seed oil contains up to 25% GLA, compared to the 17% from blackcurrant oil and 9% from evening primrose oil.

The importance of GLA to the body’s biochemistry is inestimable, and cannot be overstated. It is not so much the GLA that is so important, but the prostaglandin to which it is converted in the body. Prostaglandin E1 is a hormone-like substance that plays a part in many of the biochemical and metabolic processes of the body. Examples include the control of the immune system and inflammatory response, some kidney functions, and the tone of the arterial muscles, so important in the health of the cardiovascular system.

A good fatty acid metabolism benefits some very important aspects of our health such as maintaining a good blood pressure, low cholesterol levels, preventing inflammatory and immune system conditions such as arthritis, allergies and some skin diseases such as eczema and psoriasis, and also improving the strength of the keratin-dependent tissues such as our nails and hair.

A deficiency in essential fatty acids also seems to stimulate the overproduction of a hormone in women called prolactin that can lead to the severe mood changes commonly referred to as pre-menstrual syndrome, or PMS. GLA appears to have a beneficial effect in the treatment of PMS, and some other conditions such as breast discomfort.

Gamma linolenic acid is created in the body from linoleic acid, of which there is a plentiful supply in margarine, vegetable oils and many processed foods, but there is a problem. Fatty acid molecules come in different isomeric forms, in which although the chemical is the same, the geometry or ‘stereochemistry’ is different. The healthy form is the ‘cis’ formation, and the other is the ‘trans’ stereoisomer. The trans fatty acids are formed by hydrogenation of oils to make them semi-solid, and more suitable for spreading. This hydrogenation process causes an irreversible change in the geometry of the fatty acid that can block the conversion of linoleic acid to GLA in the body.

Hence, although most of the western population has more than sufficient linoleic acid in their diets, many who eat an excess of trans fats have a deficiency of GLA. Some B vitamin deficiencies and a deficiency in certain minerals exacerbate this situation, and a gamma linolenic acid supplement is needed. Additional to this, the enzyme responsible for the conversion, delta-6-desaturase (D6D) can be affected by many modern environmental factors such as smoking, stress, alcohol, excessive animal fat consumption and even excessive linoleic acid consumption. The solution to all of this is GLA which does not require any enzymes for its creation, and supplemental GLA from any source can immediately take part in the biochemical pathway to the creation of the prostaglandin Eicosanoids.

GLA provides the means and the resultant prostaglandins carry out the job of regulating the hormonal activity within human biochemistry. Prostaglandins help to regulate the function of many of the cells in the body, such as the smooth muscle cells of the arteries and veins that cause constriction or dilation, and on the stickiness of blood platelets causing their aggregation. They are important in the regulation of such functions as blood clotting, fluid balance and the production and balance of hormones. The anti-inflammatory properties of prostaglandin E1 are very important to the way that the body reacts to breaches by foreign invaders, and it is also thought to act to thin the blood and cause dilation of blood vessels, hence its effect in lowering the blood pressure.

So what does this mean to you, apart from the effects of the fatty acid on PMS? Borage oil can be used to treat a large number of different symptoms associated with a shortage of GLA and prostaglandin E1, and here are a few of the conditions for which a GLA supplement has been found beneficial.

A deficiency in GLA and other essential fatty acids can lead to loss of bone mass and subsequent osteoporosis and it is thought that fatty acids help the absorption of calcium by the digestive system, and to increase its deposit in bones. It can be used to increase bone mass and density and therefore strengthen the bones of those affected by osteoporosis. This is partially due to the hormone regulatory effect GLA has on the body.

Allergies appear to be very personal responses by the immune system to specific substances, and while borage oil has proved beneficial in a few allergies, and prostaglandins are known to regulate the activity of the immune response, the effectiveness of GLA treatment for allergies has been mixed. There is evidence that it can affect some cases, but not most.

GLA from borage oil can reduce the swelling and pain of rheumatoid arthritis, and helps to ease morning stiffness. Its effectiveness seems mixed, and you should try it for two or three months to determine if it helps you personally. Be careful, however, since some believe that it might react with some of the non-steroidal anti-inflammatory drugs (NSAID) used to treat this condition. Ibuprofen is one, so check with your physician before trying it.

If you suffer from high blood pressure, borage oil used in conjunction with Omega-3 fish oils might lower it, though more research is needed. There is a belief that the GLA is not the active agent here since Omega-3 oils are known to help to reduce hypertension, though the effect of prostaglandins on the factors that can reduce blood pressure is inarguable.

The healing power of borage oil should not be underestimated, and it has been used for centuries in folk medicine to treat many conditions, especially those that science has found to be caused by the immune system and the inflammatory response. Borage oil can be found at any Health Food Store.

Are Inflammation, Immunity, And Allergic Reactions A Role For Supplements?
TopPreviousNext

Author: Darrell Miller (dm@vitanetonline.com)
Subject: Are Inflammation, Immunity, And Allergic Reactions A Role For Supplements?

Inflammation, immunity diseases and allergic reactions are all connected with your immune system, and the way the body reacts to what it considers to be foreign invaders that are a risk to your health. Although you may not understand that all three have the basic underlying cause, in fact they do, and here is why.

Inflammation manifests as pain and swelling in the inflamed area, and not only can the area also get hot, but it can also raise your temperature in general, commonly called a fever. Fever is the body’s way of raising temperature above that at which foreign organisms such as bacteria and viruses can live, so any inflammatory condition that results in fever by definition must be an immune response through the body trying to eliminate foreign invaders.

If your body gets injured in any way, your immune system responds, and usually calms down again if decides that the injury is not serious. Your immune system is actually initiated by what are known as pro-inflammatory hormones, such as prostaglandins that stimulate the nerves to signal pain and swell the blood vessels close to the injury to make room for the large white blood cells when they arrive. That also allows blood and plasma to rush out and cause swelling at the site of the injury. Other prostaglandins act to quell the immune response, and get your body back to normal.

Another such hormone is a cytokine, which informs the brain of the intrusion. Some cytokines called leukocytes stop the immune system when necessary to prevent the destruction of healthy tissue, and also halt the inflammatory response. If the leukocytes are not working properly, the body can be severely damaged as the immune system becomes uncontrolled and starts to attack healthy tissue.

Then there are the histamines that allow you to expel the agents causing the problem by sneezing, watery eyes, runny noses and scratching. They lead lymphatic fluid and blood to the site of the problem in order that the invasion can be attacked and destroyed.

It is the histamines that provide what is commonly referred to as an allergic reaction, which is really the immune system coming into action to remove invaders such as pollen, dust mites and any other agent that can cause an allergy. Immunity is caused by introducing small amounts of the agent into the blood, so that the immune system can develop a memory of them. Then, when the same invader returns at a later date, the system can immediately attack them with the antibodies that have been produced.

All of these: inflammation, immunity and allergies, are caused by the reaction of the immune system to what it perceives as an invader. Normally these are bacteria and viruses, but sometimes they react to other foreign bodies such as pollen. In some people this provokes no response at all, while in others it provokes the immune system to create antibodies against the pollen, and emit histamine to expel it.

Substances that cause allergies are referred to as allergens. Many allergens are environmental, such as dust, pollen and peanuts. Some people are allergic to certain animals, such as cats or dogs, and others to chemicals in the air such as hydrocarbon emissions, particularly when in particulate form.

The symptoms can be simple, such as a runny nose, a cough and hay fever or more complex such as hives, eczema and asthma. All of these are caused by the immune system reacting to an invader. There are also foods that cause internal inflammation, such as shellfish and whitefish, eggs and tomatoes. Many of these can be extreme, leading to serious illness and can even be fatal. So what can be done to treat people who are particularly prone to inflammation and allergic reactions?

Omega-3 fatty acids have been found to reduce inflammation, unlike their Omega-6 cousins that appear to increase it. Omega-3 oils contain chemicals known as Eicosanoids, of which the prostaglandins are an example. While this might seem paradoxical, since prostaglandins are what set off the whole process, there are many types of these. Prostaglandin E2 is the type that leads to allergic immune reactions, and omega-3 fatty acids reduce the concentration of these in the blood.

Those who eat little fish tend to suffer more from inflammatory conditions such as arthritis and other conditions indicating a lack of control of the immune system. On the other hand, processed foods contain more omega-6 fatty acids that can promote these conditions. The major components of omega-3 oils are alpha-linolenic acid (ALA) and eicosapentaenoic acid (EPA) and also DHA, docosahexaenoic acid. These are all anti-inflammatories and have been shown to have very positive effects on inflammatory conditions such as rheumatoid arthritis, Crohn’s disease and eczema. Each of these is a different type of inflammatory condition caused by inappropriate immune response.

However, it not just fish oils that can help resolve problems with our immune system. Quercetin is what is known as a flavonoid. It is a strong anti-oxidant and natural anti-histamine that combats histamine release and the swelling associated with the immune response to allergens. It also counters the inflammatory agents of arthritis and so helps to reduce the pain associated with many of these conditions. It appears to work better in conjunction with bromelain, a very powerful anti-inflammatory that also possesses anti-allergen response properties. Bromelain is extracted from pineapple stems.

Another natural product is a resin extract that is obtained from the Boswellia serrata tree. It has powerful anti-inflammatory properties, and has been recommended for the treatment of arthritis (rheumatoid and osteo), Crohn’s disease and has been suggested as a treatment for asthma, though studies are still under way. However, world wide experience is that Boswellia is effective against gout, psoriasis and ulcerative colitis, to name another three totally different inflammatory conditions.

What all of this indicates are two things. First that inflammation, immunity and allergic reactions are connected conditions, and due to either poor control over or an over stimulated immune response to what the body perceives as being abnormal, in the way that hormones and other chemicals that are used to control our immunity detect it to be.

Secondly, there are many natural products that can be used as supplements to treat these effects caused by the immune system, and that their effectiveness has been proven, if not by scientific study, then by generations of traditional application as treatments of the symptoms of the conditions concerned.

However, although many have been proved by scientific study, others have not, and you should always refer to your physician before undergoing any treatment other than that prescribed. Also, there is incontrovertible evidence that the role for supplements in the treatment of inflammation, immunity and allergic reactions are beneficial. Many use nothing else.

Essential Fatty Acids - Lipids, Cell Memgranes & Eicosanoids

Essential Fatty Acids and Phospholipids

Essential fatty acids & phospholipids are primary constituents of cell membranes, and as such they are vital to the makeup of the human body. Essential fatty acids are used to generate certain intra-cellular hormone-like substances, including prostaglandins and leukotrienes, which are responsible for regulating key bodily processes. Source Naturals essential fatty acid supplements are potent, effective and chemical-free.

LIPIDS, CELL MEMBRANES & Eicosanoids

Almost by definition, life is composed of cells, and cells are defined by membranes. One theory suggests that, around four billion years ago, self-replicating molecules, similar to the ribonucleic acid or RNA in our own cells, were synthesized from organic molecules. These self-replicating molecules adapted to changes in their environment to increase their potential for survival. Thus began the process of evolution that has led, over the eons, to us. One turning point was when these molecules developed membranes - envelopes which could help concentrate chemicals needed for the cell's survival. There existed in the "primordial soup" substances uniquely suited to this purpose: a class of organic compounds we call lipids . Lipids are more commonly called fats, and in this health and image-conscious age people often think of them as something to be avoided. However, the word fat refers to a variety of substances with a diverse range of chemical properties, which are essential for survival and well-being . The simplest lipids, fatty acids such as palmitic acid, consist of a hydrocarbon "tail" connected to a carboxyl group (COOH). The majority of lipids in food and in the human body occur in the form of triglycerides - a molecular configuration in which three fatty acid chains are attached to a 'backbone' of glycerol (an organic alcohol composed of a 3-carbon chain with an alcohol group attached to each carbon). The major roles of lipids can be described as energy and storage, structural, and metabolic.

Energy and Storage

Molecules can contain more or less chemical energy. In living systems most of the energy needed to drive chemical reactions is derived from oxidation. Oxygen, the ultimate electron acceptor, is a strong oxidant: it has a marked tendency to attract electrons, becoming reduced in the process. When a molecule undergoes a chemical reaction from a high-energy reduced state to a low-energy oxidized state, energy is released. This is what happens in a fire: the high-energy carbohydrates in wood, such as glucose, react with oxygen, releasing heat and the low-energy molecules of carbon dioxide and water. This is similar to what happens in metabolism.

Most of the carbon in a fatty acid chain is highly reduced, which makes fats more energy-rich than the other organic molecules that can be burned as food. This is what we mean when we say fats are high in calories - a measure of the amount of energy released when a substance is oxidized. Fats contain more than twice as many calories as carbohydrates. This makes fats an important storage fuel for most of the body.

Structure

Another important class of lipids in the human body consists of the phospholipids. Like triglycerides, phospholipids contain fatty acid chains- in this case two, one saturated and one unsaturated, attached to a glycerol backbone. Unlike triglycerides, in phospholipids the third carbon of the glycerol molecule is attached to a phosphate (a molecular group that contains phosphorus and oxygen), which is in turn attached to either an amino acid or, in the case of phosphatidyl choline, a molecule of the B-vitamin - like substance, choline.

Their unique molecular structure makes phospholipids amphipathic, which means 'likes both':

  • The phosphate-containing head group is strongly dipolar (it has positive and negative charges and can mix with water, and thus is hydrophilic, which means 'water-loving').

  • The two fatty acid chains make up a long tail group which is nonpolar (it has no charge and cannot mix with water, and thus is hydrophobic, which means 'water-hating').

    Fats, being hydrophobic, tend to separate out from water. When fat is mixed with phospholipids in the presence of water, the phospholipid molecules attach themselves to the molecules of fat and bring them into the water solution, enabling the fats to dissolve in water.

    Phospholipids form a structure called a lipid bilayer, a two-ply sheet of phospholipid molecules in which the hydrophilic head groups face outward and are in contact with the water, and the hydrophobic tails face each other on the inside of the bilayer. This structure is one of the key constituents of the cell membranes that surround every living cell.

    The lipid bilayer of cell membranes is a fluid in which membrane-embedded proteins "float." These proteins serve a wide variety of different functions. Some are enzymes, serving to carry out chemical reactions in the adjacent solution. Some are involved in signaling, in which a biochemical action in a cell is 'commanded' by means of a hormone or some such other signaling molecule. Still others are involved in transporting substances across the membrane, into or out of the cell.

    The functions of membrane-embedded proteins are dependent on a very precise balance of phospholipids for their function. Phosphatidyl serine, for instance, has a negatively-charged head group that associates preferentially with a class of membrane-bound proteins called ATPases. ATPases regulate, among other things, the balance of sodium and potassium in intra- and extracellular fluids, a balance that is necessary for the integrity of our cells and also for the electrochemical impulses that make up our thoughts and feelings. Without phosphatidyl serine, these vitally important membrane-embedded proteins could not function.

    Cholesterol is a waxy substance that is essential to the structure of cell membranes, which depend for their function on a delicate balance between fluidity and solidity. Cholesterol provides a semifluid matrix, as well as enhancing membrane fluidity. About 80% of the cholesterol the body uses is manufactured by the liver; the other 20% is consumed in food. Elevated blood cholesterol levels are associated with heart disease. Saturated fats are converted into cholesterol more readily than unsaturated fats, and polyunsaturated fats usually depress blood cholesterol concentration to some degree. Researchers have thus recommended that people lower their consumption of saturated fats and increase their consumption of polyunsaturated fats. A process called hydrogenation , in which hydrogen molecules are added, is used to harden these unsaturated fats to create solid spreads, such as margarine. This process causes formation of altered fats called trans fatty acids. Although the results are not conclusive, human and animal studies have pointed to possible deleterious effects from consumption of trans - fatty acids, which are estimated to account for 5.5% of all fats consumed by Americans. These studies include one in men and women that showed harmful effects of trans - fatty acids on blood cholesterol ratios.

    Metabolic

    When each link of a fatty acid chain contains an atom of hydrogen, as in palmitic acid, that fatty acid is said to be saturated . If two carbon links are double bonded to each other, each has one less hydrogen atom, and the fatty acid chain is said to be unsaturated. If a fatty acid contains one double bond, it is said to be monounsaturated, and if it has two or more double bonds it is said to be polyunsaturated . Certain polyunsaturated fatty acids cannot be manufactured by the body and must be obtained from the diet. These nutrients are called essential fatty acids and are necessary for the normal function of all tissues. The essential fatty acids fall into two categories:

  • (1) Those with an unsaturated double bond between the 6th and 7th carbon in the chain, called omega-6 fatty acids, which include linoleic acid (LA), gamma-linolenic acid (GLA), and arachidonic acid (AA).

  • (2) Those with a double bond between the 3rd and 4th carbons, called omega-3 fatty acids, which include alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

    In addition to being phospholipid precursors, essential fatty acids can be converted to a class of hormone like intracellular messengers called Eicosanoids. The physiologic effects of Eicosanoids are potent in minute quantities. Their effects are so powerful that they need to be produced near the site of their action and are quickly inactivated. The important Eicosanoids include the thromboxanes, leukotrienes and prostaglandins (PGs ). Prostaglandin molecules consist of a five-carbon ring with two side chains. They can be distinguished from each other by numbers that refer to the number of double bonds in their molecular side chains: 1-series PGs have one double bond, 2-series have two double bonds, and so on. Prostaglandins mediate a variety of bodily processes, including inflammatory reactions, blood vessel contraction and dilation, and platelet aggregation. The different PGs have different effects on the body, and different essential fatty acids act as precursors for different PGs.

    Important essential fatty acids in humans are the omega-6 fatty acids, which include linoleic acid (LA), gamma-linolenic acid (GLA), and arachidonic acid (AA). 1-series PGs are derived from GLA and tend to cause blood vessels to dilate and reduce the stickiness of platelets (cell fragments in the blood that help initiate blood clotting). 2-series PGs are derived from arachidonic acid and tend to increase platelet stickiness and cause blood vessels to constrict. Meat and dairy products are dietary sources of the PG2 precursor, arachidonic acid; American diets tend to be rich in these foods. The rate-limiting step for production of GLA in the human body is an enzyme called delta-6-desaturase (D6D). The action of this important enzyme can be blocked by a number of different lifestyle factors, including a diet high in saturated or trans- fatty acids and chronic alcohol consumption. A modest increase in consumption of GLA will significantly increase the ratio of GLA to AA in the tissues, which may have a beneficial effect on the homeostasis of the cardiovascular system. Supplementation with omega-3 fatty acids, such as flaxseed oil or fish oil, is beneficial for similar reasons. Omega-3 fatty acids are precursors for 3-series PGs, which reduce platelet stickiness. Series-3 PGs also tend to inhibit conversion of AA into its metabolites, the 2-series PGs.

    The lipid composition of our diets has changed radically in the 20th century. Our intake of saturated fats has increased dramatically, and trans fatty acids, which did not exist before the advent of modern food processing technology, now form a major part of our diets. We eat less fish and green leafy vegetables, important sources of omega-3 fatty acids, than our ancestors did. Far from being an inert, homogeneous substance, fat is dynamic and varied - a subtle and interactive matrix for many of the biological processes taking place in our bodies, minute by minute.

    The red wine phenolics trans-resveratrol and quercetin block human platelet aggregation and eicosanoid synthesis:

    Implications for protection against coronary heart disease Authors: Pace-Asciak, Cecil R.a; Hahn, Susanb; Diamandis, Eleftherios P.b; Soleas, Georgec; Goldberg, David M. Affiliations: a.

Andres Wines Ltd., Grimsby, Ontario, Canada Keywords: Atherosclerosis; Thromboxane B2; Hepoxilins; Anti-oxidants; Resveratrol; Quercetin

    Abstract:

    A number of lines of evidence suggest that red wine may be more effective than other alcoholic beverages in decreasing the risk of coronary heart disease (CHD) mortality. This protection over and above that due to ethanol itself may be explained by phenolic components with which red wines are richly endowed. We have studied the effects of the trihydroxy stilbenetrans -resveratrol on human platelet aggregation and on the synthesis of three Eicosanoids from arachidonate by platelets, i.e. thromboxane B2 (TxB2), hydroxyheptadecatrienoate (HHT) and 12-hydroxyeicosatetraenoate (12-HETE). These effects were compared with the actions of other wine phenolics (quercetin, catechin and epicatechin) and antioxidants (a-tocopherol, hydroquinone and butylated hydroxytoluene). trans-Resveratrol and quercetin demonstrated a dose-dependent inhibition of both thrombin-induced and ADP-induced platelet aggregation, whereas ethanol inhibited only thrombin-induced aggregation. The other compounds tested were inactive. trans-Resveratrol also inhibited the synthesis of TxB2, HHT, and to a lesser extent 12-HETE, from arachidonate in a dose-dependent manner. Quercetin inhibited only 12-HETE synthesis, and hydroquinone caused slight inhibition of TxB2 synthesis, the remaining compounds being ineffective. De-alcoholized red wines inhibited platelet aggregation; their ability to inhibit the synthesis of TxB2 but not that of 12-HETE from labelled arachidonate by washed human platelets was proportional to their trans-resveratrol concentration. These results are consistent with the notion that trans-resveratrol may contribute to the presumed protective role of red wine against atherosclerosis and CHD.

  • red wine with alcohol removed or present reduced platelet aggregation - preventing platelets from sticking to the artery walls.
