Nutrition Guide For Fructose Malabsorption
In the table below there are lists of foods – safe to eat, to try, and to avoid in fructose malabsorption (FM), according to several dietitians’ and fructose malabsorbers’ recommendations. The list may serve only as the orientation, since absorption of fructose and other nutrients may vary considerably among individuals with FM, so everyone should make lists of not/allowed foods and their tolerable amounts, according to personal experience. In small children, fructose absorption often improves with age.

|SAUCES AND SPICES||Basil, bay, cinnamon, cumin, curry, marjoram,|
oregano, parsley, rosemary, thyme.
Coriander, garlic, onions, parsnip, spring onions.
|Sauces: Barbeque’s, Sweet&Sour, Hot mustard, chutney, ketchup, relish, soy sauce, vinegar (apple cider, balsamic);|
Spices: chervil, dill weed, ginger, hot chili pepper, pumpkin pie seasoning.
|DRINKS||Water: tap water, non-flavored bottled water, mineral water, tea, coffee (not chicory based coffee substitutes).||Fruit juices: blackberry, cranberry, white grapes;|
Alcohol: dry white or red wine (1 glass/serving).
|Fruit juices (apple, apricot, mango, orange, pear, peach, prune, sweat cherry), soft drinks with sorbitol or HFCS; alcohol (except dry white wine); powdered sweetened beverages, sweetened milk/vegetable/soy drinks, coffee substitutes with chicory.|
|WHEAT (containing fructans)||Individuals with FM who cannot safely eat wheat (white bread, pasta, breakfast cereals etc) may also have problems with artichokes, asparagus, chicory roots, chicory greens (whitlof, Belgium endive), chicory based coffee substitutes, dandelion greens, leeks, onions (after cooking, throw onions away and enjoy the taste), radish, spring onions. Tiny amounts of wheat in wheat thickener, maltodextrin and dextrose are not problematic.|
|BEANS (containing raffinose, galactans)||Individuals with FM who cannot safely eat beans may also have problems with other legumes (peas, soy, lentils), broccoli, Brussel’s sprouts, cabbage, cauliflower, kale, turnip greens, and whole grains.|
|ADDITIONAL LOW FRUCTOSE DIET TIPS||Cooked vegetables (like carrots) may have higher fructose content then raw ones. Whole-grain bread has more fructose than refined bread. Brown rice has more fructose than white rice. New potatoes have more fructose than old ones. Medications like antibiotics, vitamins and supplements, often contain fructose or sorbitol, so it is suggested to find their fructose/sorbitol free alternatives.|
NOTE: the above list of safe foods is pretty strict. A person with mild fructose malabsorption will be probably able to safely eat most foods from to try list and even some foods from to avoid lists.
Individuals with fructose malabsorption often have lactose, glucose or gluten intolerance, so they might need an additional lactose-free, sugar-free, gluten-free or FODMAP diet.
The following substances, listed on food (and supplements) nutrition facts labels, may be problematic in fructose malabsorption:
- Corn syrup solids
- Fructose (fruit sugar)
- Fructooligosaccharides (FOS)
- Fructose-glucose syrup
- Fruit juice concentrate
- Galactooligosaccharides (GOS)
- High fructose corn syrup (HFCS)
- Hydrogenated starch hydrolysates (HSH)
- Invert sugar, saccharin, sucanat
- Sugar alcohols
The list above is probably not complete (some polyols ending with -tol are missing), but the point is that not just any “food additive” or “sweetener” is problematic in FM.
The following substances, listed on nutrition fact labels should NOT be problematic in FM (and if they are, this is probably from other reasons than FM):
- Acesulfam potassium
- Artificial dyes
- Essential oils
- Modified starch
- Protein hydrolisate
- Sodium nitrite (and other nitrites and nitrates)
