There are many other potential dietary triggers of gut symptoms.Gluten can induce symptoms in patients with celiac disease (known or undiagnosed), but gluten is not present in any enteral formula.Likewise, dietary chemicals, including amines, glutamates, and salicylates, which are implicated in triggering gut symptoms in patients with IBS, are not likely to be present in formulae. However, potential dietary allergens may be present in any formula that contains whole or partially hydrolyzed proteins.
