More on Omega-3s

You all know that I am into omega-3 fatty acids. I gave you a list of the best fish to eat that are high in omega-3s and low in mercury and other environmental contaminants. I followed up with a list of non-fishy sources that are high in this essential nutrient.


Believe it or not, I have more to say on this subject. While this may seem obvious, it wasn't to me: plant based omega-3s and animal based omega-3s are different. Yep, they are similar enough to have the same name, but on a molecular level they contain different amounts of carbon. This means our bodies process them differently.

Plant based omega-3s are known as ALA (alpha-linolenic acid), while EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid) are found in fish and meat (lamb is relatively high in omega-3s). Most importantly, the studies on the benefits of this fatty acid have been performed on EPA and DHA, the omega-3s found in meat. While the human body can convert ALA into DHA and EPA it does so quite slowly.

Well, I for one am going to try to work more of those fatty fish into my diet. How about you?
