The diet may be used as part of the bowel preparation before a diagnostic procedure such as colonoscopy or as a short-term therapy for acute stages of gastrointestinal illnesses such as Crohn’s disease, diverticulitis, bowel obstruction, and ulcerative colitis. A low-fiber diet is not a no-fiber diet. A review article recommends less than 10 grams of fiber per day. Some diets recommend limiting servings of baked goods to 2 grams per serving. Some diets allow additional raw fruits such as very soft apricot, canned fruit cocktail, grapes, peaches, papayas, plums, or citrus fruits without membrane,        but two rule out all raw fruits. Many diets specifically recommend tomato sauce     and prohibit pickles. Some diets allow smooth peanut butter   or smooth nut butters.
Your health care provider might recommend that you follow a temporary low residue diet LRD if you are recovering from recent bowel surgery e. This includes undigested and unabsorbed food which consists mostly of dietary fibre, bacteria, and gastric secretions. The goal of a LRD is to decrease the size and frequency of bowel movements in order to reduce painful symptoms. It is similar to a low fibre diet LFD except that a LRD also limits some other foods, such as milk, which can increase colonic residue and stool weight. The LRD may be beneficial for symptom management during heightened or acute episodes of increased abdominal pain, infection, or inflammation. However, be aware that this diet is not recommended for all those suffering with inflammatory bowel disease or other chronic conditions. LRD will not decrease inflammation nor will it improve the underlying cause of your condition. Following a LRD for a prolonged period might lead to nutrient deficiencies and other gastrointestinal symptoms e. Your physician or dietitian can help you decide if this diet is right for you and the appropriate length of time for you to follow it.
