Research and consider trying the Candida diet. Your food isn't getting processed fully and it sounds like some of this is coming out of the pores of your skin. You need to cleanse your body to help rebuild your immune system, and boost the acid in your stomach to balance things out so your food starts getting digested fully once again. The diet is hard, but if you stick with it you'll see that it does work to greatly reduce your reactions. You may lose quite a bit of weight if you do it so prepare for that. Good luck to you.
Honestly, i eat whatever i want. Use to only get poultry and fish before PATM started eating beef again and my reactions are not as bad. I make sure i take more than recommended of garlic pills, gas pills, and acid reducer. I also walk my food out especially after eating a big meal. PATM must have something to do with acid reflux, the immune system, and some form of gas. They all seem to play a major role in this "disease."
