I guess I should study Ayurvedic food principles too. I have read a bit about Sattvic ideas. I wish I could integrate all the dietary information I get into some kind of truth!! I know from my own experience that the body's handling of water is very important (re: the vegetable astringency). I think I basically have a fluid imbalance from too many cooling foods. People seem to be attracted to cooling foods when they are stressed. Another point is that we stay in darkish houses and darkish office buildings and don't have the same relation to the climate outdoors that the paleos had, so how does that alter our food and water intake?! The reason I get into these fine points so much is because I'm interested in healing and quite often despise modern medicine. The more in tune I am with what is best for my body the more I am able to do. With me, that's a big point since I'm 49 and still running around like the proverbial chicken! There is too much I'm required to do (have 5 kids) and too much I want to do! Mary Jackson
