Fermentable oligosaccharides, disaccharides, monosaccharides and Polyols.
The low FODMAP diet was designed by researchers at Monash University to improve IBS symptoms. The diet focuses on removing carbohydrates that are high in fermentable oligosaccharides, disaccharides, monosaccharides and polyols. This diet is also used for SIBO because high FODMAP carbohydrate foods can ferment in the gut and feed a bacterial overgrowth. Monash University has a blog that features FODMAP recipes, a $10 diet booklet, and a low FODMAP app for apple or android phones.
