> ps. Body can synthesize omega-3 if there is enough α-linolenic acid (ALA) available. IIRC, ALA is an Omega 3, just one the human body doesn't use for much. The body can synthesize EPA and DHA (which it does use), but humans are pretty bad at that. It's totally conceivable that the rate of synthesis evolved in the context of regular dietary intake of EPA/DHA, so never needed to provide for all the body's needs.
