A year ago I took off Dairy and Caffeine from my diet. my skin looks and feels way better, I have had no "Attack" since.
Eat less fry food, can be hard and sad, but healthier Drink more water or natural juice and liquids.
it is believed that acidic foods is bad for AD. such as too much Vitamin C, spicy food, but I love Vitamin C (Lemon, Pineapple) and very spicy food so I don't know about that.
