What is a good diet for people with fructose malabsorption?


Quick Answer

The American Gastroenterological Association suggests that patients with fructose malabsorption ascribe to a diet that avoids foods high in fructose, including fruits, fruit juices, dried fruit, honey, soft drinks and alcohol. Mayo Clinic explains that patients should read food labels to avoid ingredients such as high fructose corn syrup, agave syrup, invert sugar, maple-flavored syrup, molasses, sorghum, palm sugar and coconut sugar.

Celiac disease expert Dr. Amy Burkhart recommends taking fructose avoidance one step further by eliminating other foods such as dairy products, wheat, garlic, onions, beans, lentils and artificial sweeteners. Burkhart explains that all of these substances may cause inflammation in the digestive tract, so someone with fructose malabsorption should consider a diet eliminating all possible sources of swelling. According to Burkhart, everyone with the malady should follow a strict diet for four to six weeks before reintroducing one fructose food every four days while recording the body's reaction to the fructose.

The AGA recommends that patients keep a food diary to discover what foods work best for fructose malabsorption. Some fructose is usually fine for patients with the disorder, but a food diary that records how a body reacts to food reintroductions is a good way to ascertain how much fructose is too much. Symptoms of fructose malabsorption include gas, bloating, cramping and diarrhea due to increased gas in the intestines from undigested fructose. Bacteria ferment this fructose in the intestines and cause gas to be released.
