Have you read this post by Dr. Carney about What Causes Leaky Gut?

I hope you will find that a good place to start. 

Here is a good video by Dr. Greger:

Thank you Sean. And yes, I have read what Dr. Carney wrote. Very helpful but I would like to know about the food side of it because everywhere you look at this subect it is contrary to Starch-Smart and just a vegetarian way of life, in general. I would also like to know if there are any success stories here or elsewhere. It is so discouraging to have these food and skin allergies. I want recovery so much! Sometimes, I feel so down about it. Not today, but it does happen. 

I keep a food diary to see if I can find foods that my body is reacting to. So far tomatoes and I just made a soup yesterday that I had over rice for breakfast--it had paprika. And my skin has gotten blotchy again. I know both of these are nightshades. And I've seen an article online that this is a food family that should be avoided by people like me. But potatoes are in this family. I've not seen any reaction to white potatoes but should I avoid them?
