I was born with excema and was told by a dermatologist not to eat the following foods: chocolate, nuts (of any kind), tomatoes (including any sauces made with tomatoes), heavy spices and avoid caffeine. I know exactly where I will get a rash depending on what I eat. When I ate nuts, my inside of my elbows broke out in a rash. When I ate chocolate, my tummy rashed out. When I ate tomatoes, my face rashed out. When I drink too much caffeine, my scalp rashes out and a couple of my fingers and inside of my palm get excema bubbles that are very itchy. Obviously, I know to avoid these foods so I don\'t rash out. There is no cure for excema so I would suggest that everyone check their diets and get used to bland foods until the rash clears up.
