WOW! First! I think this is an important board and I do hope to gain valuable information from others who may share some secrets on good substitutes or alternatives for foods that I cannot (should not is a better phrase as I do splurge) eat.
I notice that when I eat members of the nightshade family, my skin itches a few hours later. I do have severe eczema of the hands and feet, and thats where the itch/hotness occurs. My allergist confirmed the food allergy with testing but my dermatologist does not support a connection between skin issues and food intake.
If you do not know what the nightshades are, well they include: tomatoes, eggplant, peppers, potatoes (not 100% sure on this one).
If you must avoid, either due to allergy or by choice, the nightshades, what do you use as alternatives to them?
