The Low FODMAP (Fermentable Oligo-, Di- and Monosaccharides and Polyols) Diet is a diet that may be beneficial for people with Crohn's Disease, Ulcerative Colitis, and other forms of IBD.


What are FODMAPs

FODMAPs are sugars known as "carbohydrates" that are found in certain foods that people with Inflammatory Bowel Disease or compromised digestive systems may have trouble digesting as they are not easily absorbed.

Symptoms of Trouble Digesting FODMAPs

If you have trouble digesting FODMAPs, after you eat them, you may experience some of the following: abdominal pain, bloating, nausea, abdominal discomfort, distention, fullness.

Carbohydrates Considered FODMAPs

Fructans and Galactins
- Fructose
- Lactose
- Fructooligosaccharides
- Galactooligosaccharides

- Sorbitol
- Mannitol
- Xylitol
- Maltitol

Foods to Avoid

Apples, apple cider, apple juice, applesauce, apricots, cherries, dates, grapes, lychee, mango, peaches, pears, pear juice, plums, prunes, watermelon

Artichokes, asparagus, some beans (baked beans,
chickpeas, kidney beans, lentils) beetroot, broccoli, Brussels sprouts, cabbage, cauliflower, fennel, garlic, sugar snap peas, leeks, soy products, okra, onions, peas, shallots

Honey, Flavorings with fructose or sorbitol, sherry and port wine, sweeteners such as sorbitol, mannitol, xylitol, maltitol, and isomalt used in sugar-freegum, candies and mints

Suppliers of SCFA Through Fermentation

Certain components of the low FODMAP diet, specifically galacto oligosaccharides, can alter the microbiome in a positive direction through the desirable effect of increasing the population of bifidobacteria and lactobacilli (good bacteria). But the gas produced during fermentation of the components of a diet containing FODMAPs causes the discomfort mentioned above. But with the gas, short-chain fatty acids (SCFA) are also produced as the end products of oligosaccharide fermentation. Healthy populations show higher production of SCFA, and this is considered to be a healthy process. One specific component of the types of foods to avoid, galacto oligosaccharides, have been shown to produce lower amounts of gas during fermentation than Di- and Mono-saccharides, and yet increase the population of bifidobacteria and lactobacilli, and increase the healthy short chain fatty acids as a result.

Its not a gluten free diet but you avoid wheat and rye. Trace amounts are consider ok.
