New research carried out in 2012 on the Omega 3 fatty acids have questioned some of their main protective capabilities; capacity that now we believed unassailable as steel.
The shocking truth appeared in the Journal of the American Medical Association. Reviewing a number of searches performed so far, the researchers have basically concluded that Omega 3 polyunsaturated fatty acids are not associated with a lower risk of cardiac death; This means in practice that consume this type of "good" fats do not put away from a possible stroke, or heart attack. However, the systematic review in which they have been subjected to three basic forms of these miraculous natural fatty acids, however, have significant health benefits.
First of all, help to keep clean our arteries, freeing them from cholesterol, and improve the multiple activities of the brain, including cognitive and memory. Polyunsaturated fatty acids Omega 3 are on the list of five basic foods and nutritional needs of the five that should never miss, every day, on our tables; and it should also be a fundamental ingredient of the diet of expectant mothers, because they promote proper development of the fetus.
"Alpha-linolenic acid is found in nuts and in vegetable oils such as flaxseed oil, olive oil and soy. The body converts it into DHA, in small amounts.
"Docosahexaenoic acid the noblest of three, is found mainly in fish oil. I am still a few people who do not have enough of the benefits of this important fatty acid, especially if we consider that the conversion of ALA to DHA is minimal and fleeting.
"Eicosapentaenoic acid is also in fish, then the assorbirai only if you make the stock up your daily dose of DHA.
The authors reviewed over 20 studies, or 68,680 patients. The groups involved in the experiment were fed doses of Omega 3 from nature or from supplements. After two years, there has been no significant change in the number of cardiac deaths, heart attacks or strokes.
Despite these new, somewhat discouraging results, the Food and Drug Administration, or AIFA American, believes, however, important not to limit the consumption of Omega 3 fatty acids, capable, among other things, to keep down the levels of triglycerides, between those responsible for strokes and heart attacks. The authors of the new research also underlined the importance of the protective effects of omega 3 against cardiac arrhythmia and high pressure.
The Omega 3 fatty acids are also able to lubricate the joints, fight wrinkles, protect eyesight, improve mood, fight acne and increase the rate of fertility in both men and women; in addition, as we said at the beginning, to keep down cholesterol levels and improve cognitive function and memory in the brain. No coincidence that Omega 3 are recommended to pregnant women: talk to your doctor, you will see that he will recommend to include them in your diet, along with the right amount of folic acid.
