Thanks for the responses. I did one of those popular blood tests that tells you what your food intolerances are and it told me I should stop eating A LOT of things - a lot of meats and animal products, certain grains, peanuts, sugar cane, corn, gluten, etc. I noticed that I felt really sick after eating any of those foods and I started cutting them out. But what I was left with wasn't nutritious enough and I still felt like crap all the time and I was stuck in this downward spiral of cutting out more and more foods. I know other people going through that same spiral and their health is deteriorating. After doing a lot of research on nutrition (most books seemed to come from the Weston A. Price Foundation, hmm...) and exploring more recipes I gradually started adding foods back in my diet and now I am eating copious amounts of meat and animal products, although I am still wary of grains and sugars and will ferment them before I eat them. But I can handle a bit of crappy food now that my body is strong enough and I don't have to be "that person that can't eat anything" at a restaurant or going over to someone's house for dinner.
