FODMAPs are a group of short-chain carbohydrates, sugars, and sugar alcohols that are found in various foods and may be poorly absorbed in the intestines. The name comes from the English Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols — fermentable oligosaccharides, disaccharides, monosaccharides, and polyols.
A low-FODMAP diet is used for irritable bowel syndrome, especially if symptoms persist after basic dietary correction. Its essence is not the permanent exclusion of foods, but a temporary restriction for 2–8 weeks, followed by the gradual reintroduction of foods to identify individual triggers.
