As of 2015, the International Foundation for Functional Gastrointestinal Disorders includes a variety of IBS diet information at its official website, AboutIBS.org. The site includes plans for a 12-week elimination diet for IBS patients. Healthline offers explanations regarding several diets that are recommended for IBS patients. WebMD also provides information and guidance about IBS diets, including a low-FODMAP, or fermentable oligo-, di-, monosaccharides and polyols, diet.
There is no advice about diet that works for all irritable bowel syndrome patients, according to the International Foundation for Functional Gastrointestinal Disorders. However, patients can find dietary triggers and receive more specific dietary advice from their physicians by keeping a diet and symptom diary. Some patients find it helpful to eat smaller meals throughout the day instead of three large meals; eat foods slowly; not skip breakfast; and avoid heavy, high-fat foods.
Chocolate, insoluble fiber, coffee, caffeine and nuts are some of the foods most likely to cause intestinal issues in IBS patients, reports the International Foundation for Functional Gastrointestinal Disorders. Common IBS symptoms include cramps, abdominal pain, diarrhea or constipation, explains Healthline.
Some of the specialized diets recommended for IBS patients include a high-fiber diet, gluten-free diet, low-fiber diet and low-fat diet.
