risrosen, you might have leaky gut syndrome from years of eating food that wasnt right for you - gluten/grains/dairy/etc
why dont you just eat clean paleo, either all raw or some cooked (im not advocating well-done cooking here)
if you want a more sane, but less extreme talk about paleo, read robb wolfs book the paleo solution.
some of what matt stone says makes bizarro sense, but he is neither a scientist nor a serious athlete, and robb is both, has healed himself of crazy sickness and trains high performance athletes.
matt may have some interesting tricks, but robb will also get you there systematically, not via hearsay. that being said, some of matt's inspirations like schwarzbein, martin berkham, are right on in regards to useful systems, except for some of the poisonous foods they recommended. also look at the GAPS diet, and see a good functional biological medicine doctor/naturopath who understands evolutionary nutrition.
