The low FODMAP diet is a diet for people with irritable bowel syndrome (IBS). With this diet, you eat only foods low in fermentable oligosaccharides, disaccharides, monosaccharides and polyols (FODMAPs).
FODMAP is an acronym for fermentable oligosaccharides, monosaccharides and polyols, which are short-chain carbohydrates such as fructose, lactose and sorbitol.
