Fructose Malabsorption, formerly known as “dietary fructose intolerance” (DFI), is a common digestive disorder that occurs due to improper absorption of fructose (and other sugars like lactose or sorbitol) in the small intestine. What results is an increased concentration of fructose in the entire intestinal tract. About 30-40% of people suffer from F.M. That’s a lot of us considering anything over 5% is considered significant.
Not to confuse F.M. with ‘fructose intolerance’ which is a rare (1 in 10,000 people) and potentially fatal condition in which the liver enzymes that digest fructose are deficient.
