I find that when I eat pure-paleo then I feel better and am more mentaly alert. If I eat some grain products, e.g. donuts, or sprouted wheat bread, then I get mental and emotional "fog" and also my waits gains afew inches, probably some kind of bloating. That is my direct observationa and may not apply to others. Also, I don't do the "all free range antural meat" thing. I just eat what is at the supermarket. I have not yet tried a few weeks of pure free range. (yet) Richard Keene, Novell Inc, Provo, Utah, 801-861-4389, [log in to unmask]
