Nutrition - omega 3 and omega 6

Just something that caught my eye, from trifuel.com:

Explaining the Importance of Omega-3 and Omega-6 Fatty Acids in the Training Diet.

Essential fatty acids (EFA) are necessary in proper brain and nervous system function and for building new cells. Although they are essential for good health, these fatty acids cannot be made by the body. We must obtain EFA from dietary sources. The two primary EFAs are the omega-3 and omega-6. Plant derived omega-3 fatty acid is called alpha-linolenic acids, marine derived omega-3 is also know as eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA). Omega-6 fatty acids are also called linoleic acid.

The role of EFAs in human nutrition has long been recognized. Research links EFA intake with reduced risk for coronary heart disease (CHD), improving blood cholesterol levels and regulating the inflammation. This is beneficial for all individuals, regardless of physical activity level. However there is recent evidence, of great interest to triathletes, demonstrating a link between intake of EFA and improved fatty acid metabolism with increased fat oxidation and reduced fat synthesis. This could be good news for triathletes, so let’s take a closer look at the research and the benefits of EFAs.
