Unfortunately for me, I have given up foods and then become even more sensitive to them than I was before. This has happened to me with gluten, soy, corn, and dairy. I was allergic to all of those things and having health issues because of it. I had read that some people are able to give up the offending foods, heal, and then reintroduce them in small amounts, but in my case the sensitivity increased. I can only assume that these foods are poisonous to my body because of a genetic disposition or some other reason. They aren't foods that I particularly miss anyway, so I usually don't think much of it. Gluten in general is just crap and so is soy, although I wouldn't mind being able to reintroduce small amounts of organic yogurt one day. The last time I attempted to eat yogurt my entire throat swelled up and I broke out in a rash. No thanks.
