Food plays an essential role in normal cellular processes; however, certain foods may also trigger or worsen certain disease states. This article focuses particularly on the role of food in common gastrointestinal and liver diseases, and discusses the current evidence that either supports or debunks common dietary recommendations. Nutrition topics discussed include the use of artificial sweetener for weight loss, avoidance of all dairy products in the setting of lactose intolerance, dietary recommendations for diverticular disease, and dietary management in cirrhotic patients with hepatic encephalopathy.
