FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, which are short-chain carbohydrates that are poorly absorbed in the small intestine and ferment in the colon. They are found in many foods, including fruits, vegetables, grains, and dairy products. Some people experience digestive discomfort after eating foods containing FODMAPs, such as cramping, bloating, gas, diarrhea, and constipation. The low-FODMAP diet is a temporary eating plan that eliminates high FODMAP foods from the diet to identify which ones are troublesome for an individual. The diet is often prescribed for people with functional gastrointestinal disorders, such as irritable bowel syndrome (IBS). The low-FODMAP diet is a three-step elimination diet that involves stopping certain foods (high FODMAP foods), then reintroducing them one at a time to see if they cause any symptoms. The diet is very restrictive and should only be followed for a short period of time. It is important to talk to a doctor or a qualified health professional before starting the low-FODMAP diet.
