FODMAP diet

What is the FODMAP diet? 

FODMAPs are fermentable oligo-, di-, and monosaccharides and polyols that are poorly absorbed in the small intestine.

A diet high in FODMAPs has been associated with higher levels of hydrogen produced in the breath in both IBS patients and healthy individuals as well as GI symptoms and lethargy in IBS patients, but not in healthy individuals.

Conversely, a diet low in FODMAPs has been associated with lower levels of hydrogen production in both IBS patients and healthy individuals as well as a reduction in bloating, abdominal pain, flatulence, and overall symptoms in IBS patients as compared with a normal diet.

It is likely that a low FODMAP diet reduces the fermentation of these carbohydrates and subsequent hydrogen production, therefore reducing IBS symptoms such as bloating, abdominal pain, and flatulence.
