Elimination diets can help identify food triggers for pain when performed safely and ensuring adequate caloric and macronutrient intake.

“Well, this may be a case for elimination diets, provided they're done safely, where people restrict the number of foods they eat to a very limited number of foods, make sure they still get enough calories and macronutrients that they need, protein, fats, and carbohydrates or what have you. But that by limiting the total number of foods that they eat to 8 or 10 basic things, then you can build things in and then explore what triggers the pain or what removes the pain.”
