I believe that there was a discussion recently on this list about how best to obtain an ideal ratio of omega 6 to omega 3 fatty acids--one more closely approximating that obtained by paleo H & G's. I came across an article in the "Life Extension" magazine recently that stated that a new source of essential fatty acids, alpha-linolenic perilla oil, is showing greater health benefits without gastrointestinal side effects. This oil comes from the beefsteak plant (Perilla frutescens) and is relatively common in East Asian countries. It may be superior to other oils because it is tolerable by virtually everyone. Binnie
