YES! Food elimination diet, trying to figure out food allergies , avoiding sugar, bread, ect...it drove me CRAZY! Ultimately, it's not an allergy problem b/c most of us probably ate anything we wanted before this lip condtion happened. But now, our lips are probably sensitive to some foods like Sugar or gluten or bread...it varies from person to person. This may be because some of these foods are very acidic and some feed the yeast/fungus. Now I just focus on healthy foods, avoid commonly allergenic food like soy, peanuts, cow's milk, etc. Once we are cured, we should be able to eat whatever we want IN MODERATION.
