FODMAPS are fermentable carbohydrate, an acronym for: Fermentable, Oligosaccharides, Disaccharides, Monosaccharides, Polyols. FODMAPS include: lactose in dairy, beans and legumes, xylitol, and fructose in fruits and vegetables like apple, pears, and onion.  FODMAPS can

The Low FODMAPS Diet avoids these foods high in fermentable carbohydrates.

FODMAPS pull water into the bowel and the bacteria feed on the fermentable carbohydrates creating gas.  For some people, FODMAPS can cause strong digestive symptoms such as diarrhea, gas and bloating. Studies have shown the Low FODMAPS Diet to be helpful with Crohn’s & Colitis 1, 2.  For people with SIBO (small intestine bacterial overgrowth), FODMAPS feed this bacterial infection causing gas and other symptoms, making people with SIBO more sensitive to FODMAPS.

Since so many children with autism and other developmental delays have digestive issues, for those that have problems with FODMAPS, this diet can be helpful to support gut function and healing.

    I have been following a no fruit, very few vegetable FAILSAFE/RPAH program for 4 years and just discovered through genetic testing I am +/+ for ALDOB – hereditary fructose intolerance so will be incorporating into my program. This info led me to your book pg 89-90,158,46,& 49 on glyconutrients & glycosaminoglycans (GAGS) and I am tying it into my issues with glycogen storage diseases where I have a +/+ on the ENO3 gene (type 13). I didn’t see anything on glycogen storage diseases on your site & hope you address them. Type 2 was dramatized in the film with Harrison Ford, Extraordinary Measures. Thank-you for all of your help!!!

    The FODMAP diet didn’t work for me. I had to switch to a low fructose diet, see for more info. I am currently eating less than 2 grams of fructose daily including the fructose that comprises 1/2 of sucrose foods. I am currently eating organic sushi rice, sprouted millet, sprouted buckwheat groats, farm fresh grass fed beef, turkey and chicken that is not fed soy, homemade unpasturized strained goat milk yogurt, unpasteurized goat milk butter, salt, and red or green leaf lettuce juice.
