What are FODMAPs?

William Dierenfeldt, MD
FODMAP is an acronym used to categorize the types of sugars that are naturally found in the foods we eat. The letters in FODMAP stand for:

F= Fermentable
O= Oligosaccharides
D= Disaccharides
M= Monosaccharides
a = and
P = Polyols

Different foods have been categorized as having low fermentable sugar content (friendly) or high fermentable sugar content (not friendly). Those foods that are considered NOT friendly should be avoided when following a Low FODMAP diet. 

Examples of some foods that contain high FODMAPs and are considered not friendly include:

  • Fructans are present in wheat, onions, and garlic
  • The sugar that is present in legumes (baked beans, chickpeas, etc.)
  • Lactose, the natural sugar found in milk
  • Fructose, the sugar found in  honey and some fruits and high fructose corn syrup
  • Sugar alcohols such as sorbitol, mannitol and xylitol
The Low FODMAP IBS Diet is a comprehensive plan that combines Low FODMAP dietary modification with key lifestyle changes to improve IBS symptoms.
