I noticed something interesting in the Eades book recently, before I had to return it to the library. It said that the good eicosanoids draw water into the bowel. I can't remember whether the bad eicosanoids took it out or just didn't pull it in. Also the good eicosanoids promote vasodilation vs. vasocontriction by the bad ones. These seemed like pertinent facts. I checked out Enter the Zone and couldn't find any more information on this. I've become very familiar with glycemic response after restudying Rick Mendosa's site at www.cruzio.com. He also mentions a satiety index which was a new one on me. Mary J.
