Charlie, you might have other food intolerances which you have no idea about (aside from grains, dairy etc). I never would have thought some of the foods I reacted to were even bothering me eg. blueberries, pear, pineapple, green beans, red kidney beans, flax, cod..HEALTHY foods! I was always sluggish and cranky. I would encourage you to get the test for multiple foods. I used alcat, but I know elisa is another one that Dr. O recommends. Once I gave up all the foods I reacted to, I have been feeling a lot better (especially more energy) and finally gaining some weight that had been long awaited. Good luck!
