"How Do You Figure Out If A Rash Is Actually a Sign of Food Allergy?"
It can be very tricky to determine if food is causing eczema flares, said Scott Sicherer, MD, director of the Jaffe Food Allergy Institute at the Icahn School of Medicine at Mount Sinai. “Most of the time when food is a suspected trigger, the relationship is proven with medically supervised feeding tests. This is no surprise because scratching, infection, changes in temperature, exposure to allergens in the air, and even changes in mood, can result in flares.” He added that it is important to have a skin-care regimen in place to keep the skin in the best shape possible; taking into consideration that atopic dermatitis has many triggers. Managing food allergy and eczema is complicated. Do work with your allergist to get specific advice.
