Nutrition and food items may improve or worsen symptoms in Crohn’s disease and ulcerative colitis. Protein malnutrition and vitamin and mineral deficiencies are common, particularly iron and vitamin D. Dietary fibres and omega-3 fatty acids are safe, but no evidence supports their use as treatment. The use of probiotics is not encouraged in patients with Crohn’s disease, but it may maintain remission in ulcerative colitis. Curcumin, chamomile and other herbal extracts are promising in mild ulcerative colitis treatment, but product validation and side effect monitoring do not suffice.
