Sorry half personal experience and other half from nutrition business journal. Final tip, be careful with bagged salad mix especially at restaurants. Redleaf lettuce is high in nutrients but yeasts love that. Next time you're near that stuff look closely at any breaks in the leaves, if you see dark especially black avoid. The dietary suggestions from my earlier comment helped me recover from painful hives from boarder line lupus. Totally recovered and still eat white bread sometimes, but more spelt bread, rice and pasta.
