Many people with bloating and diarrhea get diagnosis of IBS. But actually they may have frucose malabsorption - FM (or lactose intolerance or celiac disease) in which some fruits, vegetables, sugars and other products rich in fructose or sorbitol can't be tolerated. The problem is impaired absorption of fructose and sorbitol in small intestine. Treatment is with low fructose diet.
Problematic nutrients in FM are: FRUCTOSE, HFCS, SORBITOL and other POLYOLS (maltitol, mannitol, xylitol) and, only in some individuals FRUCTANS.
Most problematic foods are:
- FRUITS: apples, pears, prunes, peaches, sweet cherry, dates, raisins, mango, papaya.
- FRUIT JUICES, JAMS, COMPOTES.
- SUGARS and SWEETENERS: fructose, High Fructose Corn Syrup (HFCS), sorbitol, xylitol, mannitol, maltitol, raw sugar, brown sugar, molasses, Splenda.
- "LOW CALORIE" FOODS AND DRINKS and "sugar free" chewing gum with added sorbitol or xylitol
- WHEAT (contains fructans)
- VEGETABLES: onions, tomato, Jerusalem artichoke, leeks
Low Fructose Diet Details:
Those who have ONLY FM without lactose intolerance, small intestinal bacterial overgrowth, celiac disease or intolerance or allergy to some specific food CAN PROBABLY SAFELY EAT:
1. The first thing when you have FM is to find out if you can tolerate foods with fructans: WHEAT, ONIONS, JERUSALEM ARTICHOKES, LEEKS. Most of affected persons can at least in small amount.
2. BREAD and PASTRIES of any kind - without fructose or HFCS
3. CEREALS, CORNMEAL, OATMEAL and the like - if nonsweetened
5. MEAT - but there is often fructose in breading and some packaged meat products are sweetened with HFCS
6. FISH - canned fish may be sweetened
7. DAIRY - if nonsweetened
9. VEGETABLES, except sweet ones like beats, cooked carrots, sweet potatoes, canned prickles, etc.
10. Many persons with FM can safely eat BANANAS, ORANGES, GRAPEFRUIT and LEMONS (low in fructose). Many can also eat all kind of berries.
11. PLAIN or MINERAL WATER (nonsweetened), NONSWEETENED TEA. FRUIT JUICES from above mentioned fruits may be ok. DRY WINE and other NONSWEETENED ALCOHOL in limited amount may be ok, but it can aggravate SIBO so find out by yourself if it triggers symptoms in your case..
Glucose and sucrose - table sugar are not recommended despite the fact that they help in absorption of fructose because they are often not tolerated and may cause small intestinal bacterial overgrowth (SIBO).
