More evidence of the importance of omega 3 fatty acids
Posted by omohundro on September 25, 2007
The human body needs but cannot make two forms of “essential fatty acid” called omega-3 and omega-6. The modern American diet generally provides enough omega-6 but is quite lacking in omega-3. Omega-3 is only synthesized by certain plants (eg. flax, walnuts and certain forms of algae). Historically humans got their omega-3 by directly eating those plants or by eating fish or game animals which ate them. In modern times, however, farmed fish and animals have been fed diets based on corn and grains rather than grasses or algae and therefore have much lower levels of omega-3.
The omega-3 fatty acids are critical for proper membrane functioning and are especially important for the neuronal membranes in the brain. Studies have shown connections to autism, memory loss in old age, schizophrenia, bipolar disorder, and learning disorders. It has also been shown to have a significant impact on immune function and arthritis. Other studies show impact on cancer, heart disease, and cholesterol:

The most recent study shows “a relatively large effect” in protecting against diabetes:

There are a variety of omega-3 supplements and they are usually based on fish oil or flax seed oil. Unfortunately, in oil form omega-3 is extremely sensitive to both heat and light. The oils go rancid very easily and quickly and the breakdown products are bad for you. Conditions must be carefully controlled during manufacturing, shipping, and retail sale. Stores like Whole Foods have refrigerated cases for selling these oils and they are packaged in dark bottles. A brand I’ve been using and am happy with is “Udo’s oil”:

It has a somewhat nutty flavor which takes a bit of getting used to. Since starting to take it daily, I noticed an immediate effect on both my skin and immune system. His book is a worthwhile read as well:
