Other Diets

Lactose-intolerant IBS patients benefit from a lactose-free diet, and patients with fructose malabsorption or intolerance, should exclude fructose from diet. Some patients with IBS-D report exacerbation of symptoms by certain foods and try exclusion diets. This situation is considered a food sensitivity and not a true food allergy.[14] The study of Atkinson et al.[29] remains the largest on this topic. IBS patients received either an elimination diet [based on the presence of high levels of food-specific Immunoglobulin G (IgG) antibodies that were interpreted as indicating food hypersensitivity] or a sham diet. A small reduction in symptom severity was observed in the 'true' elimination diet group, with a worsening of symptoms once the eliminated foods were reintroduced.[29] Recent small studies also reported favorable results on gastrointestinal symptoms using this strategy.[30] However, there is insufficient objective data to routinely recommend IgG antibody testing.
