If you have been diagnosed with fructose intolerance or fructose malabsorption, you may have to limit the foods you eat that contain fructose. Fructose is a sugar found naturally in many foods and used as an artificial sweetener in many other products. According to MayoClinic.com, eating too much fructose can lead to kidney and liver problems for those who suffer from a genetic intolerance.
Fruits
Many fruits contain fructose, but not all of them need to be avoided. According to the University of Virginia Health System, fruits like pineapple, berries and citrus are more friendly to those with a fructose intolerance. On the other hand, apples, cherries, pears and grapes are all significant sources of fructose. In addition, you should avoid juices made from these fruits if you are looking to cut back on your fructose.
Vegetables
While some vegetables contain fructose, according to the University of Virginia Health System, the benefits outweigh the concerns, so you may be able to eat them even if you're on a low-fructose diet. Per 100 g of food, cabbage contains 1.2 g of fructose, sweet potatoes contain 0.5 g of fructose and onions contain 1.29 g of fructose, according to the USDA Nutrient Database. Compare that with 100 g of apple, which contains 7.6 g of fructose. Even the highest-fructose vegetables pale in comparison with fruits and sweeteners.
Sweeteners
Sweeteners, both natural and artificial, are the highest-fructose foods by far. Honey contains 42.4 g of fructose per 100 g serving, which is six times more than the same amount of an apple. High-fructose corn syrup is used as an artificial sweetener in everything from sodas and sports drinks to cereal and sauces. Like honey, it also has 42.4 g of fructose per 100 g serving. And sorbitol, a sugar alcohol used as a sweetener, turns into fructose in your digestive system, according to MayoClinic.com.
