I have heard that a gluten free diet can be helpful; however, I have not done this myself. I am unsure if there has been any conclusive research in this area. When I was experiencing 10-12 oral lesions at a time intended to avoid more acidic foods that would hurt and exacerbate my lesions. I avoided orange juice, tomatoes/tomato sauces, salads with acidic dressings, crunchy breads/toast that could scrape or poke at any lesions, etc.
