What I read from the British National health web page, Mayo web pages and other PMR articles is this: Keep away from processed food, eat gluten free which means nothing with wheat in it, stay away from nightshade vegetables that's potatoes, tomatoes, egg plants and peppers. nothing with vinegar in, no fermented items, no pickles, no wine or alcohol. No pork in any form, and only hormone and antibiotic free chicken, grass fed beef.

Eggs, fish and cheese, thank goodness, are OK. What seems to make pain worse is the additive in modern food. The down side is pretty much everything has to be cooked from scratch and without those nightshade veggies is pretty tasteless. I have a few recipes that might be helpful. When I get a minute I'll post them here. It sounds daunting but it is workable.
