FODMAP stands for
- Fermentable
- Oligosaccharides,
- Disaccharides,
- Monosaccharides, and
- Polyols, which are short-chain carbohydrates and sugar alcohols that are poorly absorbed by the body, resulting in abdominal pain and bloating.
FODMAPs are short-chain carbohydrates and sugar alcohols that are poorly digested by the body. They ferment in the large intestine (bowel) during digestion, drawing in water and producing carbon dioxide, hydrogen, and methane gas that causes the intestine to expand. This causes GI symptoms such as bloating and pain that are common in disorders like IBS.
FODMAPs are in some foods naturally or as additives. They include fructose (in fruits and vegetables), fructans (like fructose, found in some vegetables and grains), lactose (dairy), galactans (legumes), and polyols (artificial sweeteners).
These foods are not necessarily unhealthy products. Some of them contain fructans, inulin, and galactooligosaccharides (GOS), which are healthy prebiotics that helps stimulate the growth of beneficial gut bacteria. Many of them are otherwise good for you, but in certain people, eating or drinking them causes gastrointestinal symptoms.
