A low residue diet is a type of eating plan that focuses on limiting or avoiding foods that contain fiber or other substances that can be difficult to digest. The goal of this diet is to minimize the amount of undigested material that reaches the colon, which can help alleviate symptoms such as diarrhea, abdominal pain, and bloating. There are several synonyms for a low residue diet, including a soft diet, a low-fiber diet, a bland diet, a clear liquid diet, and a liquid diet. These plans typically involve consuming foods that are easy to digest and do not contain large amounts of fiber or other potentially problematic ingredients.
