The results of a recent study suggests that people who eat omega-3 fatty acids (found in flax if you are veg, and interestingly are found in algae which is the source that ends up in fish) are less hostile and less likely to get stressed than those who don’t.

Dr. Carlos Ibarren, a researcher with Kaiser Permanente in California, analyzed the eating habits and psychological tests of 3581 urban adults aged 18 to 30 who participated in a federal heart disease study. After physical and environmental factors were accounted for, the scientists revealed that people who frequently ate diets high in omega-3 fatty acids scored lower on measurements of hostility, including cynicism and mistrust of others, anger and aggression.

These findings, published in the European Journal of Clinical Nutrition, confirmed results obtained from a Japanese study that revealed Omega-3 supplements lowered aggression in students dealing with stresses during examination periods at university.

Recent studies suggest that the omega-3 fatty acids may play a very important role in muscle and strength development as they are widely recognized for their powerful anti-inflammatory effects. However, the precise biochemical mechanism responsible for this benefit is less clear.

Researchers at The University of Michigan have revealed some important insights as to why omega-3s are so effective at reducing inflammation in muscle and other tissues. Omega-3s such as docosahexaenoic acid (DHA) and particularly eicosapentaenoic acid (EPA) significantly diminish the production of various prostaglandins; naturally occurring hormone-like substances that accentuate inflammation.

These researchers discovered that omega-3 fatty acids compete with omega-6 fatty acids for the same binding site on the COX 1 enzyme. The COX enzymes are the targets of anti-inflammatory drugs like ibuprofen, they convert the omega-6 fatty acids to prostaglandins. The more omega-3 fatty acids available to block these binding sites, the fewer omega-6 fatty acids are able to be converted to prostaglandin, thus reducing inflammation.

Additionally, although some omega-3 fatty acids are converted to prostaglandins, the prostaglandins formed from omega-3 are up to 50 times less active than those formed from the omega-6 fatty acids. Therefore, the effect is beneficial but does not interrupt the natural healing process.

Omega-3's such as EPA not only help reduce inflammation they also down regulate the genes that promote excessive muscle breakdown (catabolism). Supplementation with EPA can reduce muscle inflammation and catabolism during training; thereby, speeding recovery and muscle growth during training.

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as acetaminophen and ibuprofen are used by over 100 million people each year in the US. However, the consumption of these drugs can cause some serious side-effects including: gastro-digestion and bleeding, increase risk of heart attack, and stroke. Due to the plethora of potential side-effects associated with NSAIDs, research on safer alternatives for reducing pain and inflammation is receiving more and more attention.

Researchers from the Department of Neurological Surgery at the University of Pittsburgh Medical Center examined the effectiveness of the omega-3’s eicosapentaenoic acid (EPA) and decosahexaenoic acid (DHA) in treating inflammation. In this study, a total of 250 patients were evaluated for nonsurgical spine pain, all of which were taking NSAIDs. Each subject was then given a 2.4 gram per day dose of omega-3s for two weeks followed by a 1.2 gram dose per week for 8 weeks. Follow-up testing was conducted via the use of a questionnaire.

Results indicated that a whopping 69% of the subjects reported a decrease in joint pain. Over half of the subjects were able to stop taking NSAIDS for their joint pain. Also, 80% revealed that they were very satisfied with the omega-3 induced changes. Best of all, no side effects were reported.

While this study presents several design flaws specifically, the lack of a placebo control group, it still underlines the clear potential of omega-3s to elevate pain and decrease inflammation. Take your flax seed oil daily!

New study suggests that increased intake of omega-3 fatty acids will improve bone mineral mass, particularly if you’re a young man. Greater bone strength is yet another benefit from increasing your intake of these essential fats.

In this study, the researchers recruited 78 healthy young men from high schools and sports clubs. At the start of the study their average age was 16.7 years. DEXA was used to determine bone density and blood samples were obtained to measure lipid profiles. The scientists retested these young men after a 7 year follow-up and they identified a clear link between omega-3 intake and bone density. This link was apparent before most of these men had reached their 23rd birthday.

Who would have guessed that the omega-3 essential fats have such a profound affect on bone health, even in such young and apparently healthy adults?

This new research is remarkable but it adds to previous studies that suggest diets low in omega-3 may promote bone loss.

Most people associate bone density concerns with their grandparents. Yet this study clearly identifies the impact of nutrition on bone health even in the formative years. It’s also a clear example of the need for an optimum approach to nutrition to build a premium physique.

Increasing your intake of omega 3’s will ensure a myriad of benefits that are essential to maximizing muscle and strength gains. Now you can add greater bone strength to this ever-increasing list.

Four out of five adults in the US don’t get enough polyunsaturated (essential) essential fats in their diet. General ignorance about a quality diet and lack of nutritional education has ensured this predicament has been passed on to our offspring - 90% of US children don’t get enough essential fat in their diets.

The problem is that essential fats such as the omega-3s are absolutely paramount for healthy brain development in children. Learning difficulties and behavioral problems in children are linked to a deficiency in omega-3s.

However, the results of this study suggest that this deficiency maybe easily corrected. This comprehensive, well-designed study examined the effects of supplementation with polyunsaturated fatty acids (containing omega-3 and omega-6, 3000 milligrams per day) on a large group of children with attention deficit disorder. Results showed that supplementation with essential fats significantly improved behavior of these kids.

Overall, behavior ratings obtained from the parents revealed an improvement in 9 out of 14 assessments. And remember, this study used a randomized, double-blind cross-over design. This level of scientific control means the results obtained are extremely reliable.

Other studies have linked low levels of omega-3 to depression, a decline in mental capacity and Alzheimer’s disease. At the other end of the spectrum, studies have shown that women who consume a diet rich in omega-3s give birth to babies with higher IQ’s. The brain is a unique organ when it comes to essential fatty acid requirements, it requires an extraordinarily high amount of omega-3.

In today’s typical diet this high ratio of omega-3 to other fats is very difficult to achieve without specific supplementation and that’s why deficiencies are common. Are you and your kids getting enough omega-3?

What is the best source of Omega 3s? Flax seed or its oil. Or the new EPA product that is going to be available from Vita Health. Stay tuned for more info.

Now the festive season is over, and the inevitable over-indulgence has come to an end, many people are looking to shed a few excess pounds of flab. Omega-3s might just be the ticket to help speed this process along.

Researchers from Japan have reported that omega-3s can reduce body weight by boosting fat metabolism.

The scientists report that a group of lab mice fed a high fat diet and supplemented with omega-3 fats gained less weight and metabolized more fat than their counterparts that did not receive the supplement. This study was published late last year in the Journal of Nutrition.

The omega-3 essential fats help build muscle, reduce inflammation, improve insulin metabolism, promote brain health and protect against cardiovascular disease. They are becoming the health miracle of the 21st Century.

However, the omega-3 phenomenon all started over 30 years ago with a few young Danes dog-sledding their way to Greenland to check out some Eskimos.

Danish scientist Dr. Jörn Dyerberg, then, a young researcher, set off with a couple of colleagues via dog sled over the ice and snow to check out the lifestyle of the Greenland Eskimos, or Inuit as they prefer to be called. This was back in 1970 and Dr. Dyerberg was curious how the Inuit’s could eat an extremely high-fat diet and still have one of the lowest death rates from cardiovascular disease on the planet.

The scientists analyzed blood samples from the natives and identified high levels of two long-chain fatty acids, now called eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The researchers published this landmark paper in The Lancet in 1971 and the omega-3 phenomenon began.

Now, some 14,000 papers on the omega-3s have been published, including close to 8,000 human studies.

A lot of people don’t get the results they desire from exercise, and often this comes down to a deficiency in the correct ratio of omega essential fats in the diet. With a typical diet, it’s almost impossible to get the correct ratio of omega essential fats that are vital to optimum health. The correct intake of essential fats also ensures you get the best results possible from also those hours in the gym.

Make sure you are getting your flax, safflower, walnuts, canola oils in your diet.

A study has shown that obese people receiving omega-3 fatty acids experienced better satiety from meals. Satiety simply means feeling more satisfied from the consumption of less food.

The researchers from the University of Navarra, University of Iceland and University of Cork reported that during a weight loss diet, a high-dose omega-3 supplement promoted satiety after the test meals. However, the appetite measurements were taken only during the last two weeks of the study.

A recent review of the data on essential fatty acids shows science has moved from speculation about their importance to solid evidence that, they are not only essential to optimal health, but they also provide direct protection against many diseases.

Docosahexaenoic (DHA) and alpha-linolenic acid are the two "backbones" from which all other essential fatty acids can by made. They form vital components within the phospholipid membrane of every cell in the body. Their presence within the cell membrane are key factors in the modulation of cell function. All cells need oxygen and other nutrients. Essential fatty acids within the membrane structure allow for effective transport of oxygen and nutrients into cells as well as waste products out of cells.

Yes, it's true. Eating the wrong diet can and does increase your risk of getting Alzheimer's disease. It's like karma. What goes around comes around; cause and effect. You do it, you get it or perhaps heart disease or cancer or some horrible illness if not sooner then later.

Why? Because when it comes to memory loss, we now know that there is a definite link between Alzheimer's and raised levels of an omega-6-fatty acid called arachidonic acid.

Omega-6 fats are found in high concentrations in factory-raised animals as they are typically fed grains. Poultry, cereals, eggs, and nuts are other sources, but the major source of omega-6 for most Americans is vegetable oil. Unhealthy vegetable oils such corn, canola, soybean (major GMO), and sunflower oils are largely composed of Omega-6 fats.

Because of the advent of processed foods, over the past century or so the amount of omega 6 in your diet has zoomed. At the same time the amount of healthy omega 3 has dwindled. This is a very big problem because a ton of modern research reveals that a healthy amount of omega-3 wards off Alzheimer's disease.

The most important of the omega 3 oils is DHA, or docosahexanoic acid, which has been revealed to protect your brain from damaging changes as you age. In fact, DHA increases the production of LR11, a good protein that is found in higher concentrations in a healthy aging brain as opposed to sick one.

But you don't have to be one of those dreadful statistics.

And remember this: no one ingredient stands alone.

Get some DHA, ginkgo, and PS in your diet!

Omega-3s such as docosahexaenoic acidity (DHA) and particularly eicosapentaenoic acidity (EPA) significantly reduce the development of various prostaglandins; normally sourced hormone-like ingredients that emphasize swelling.
