Hi Erin, Fructose is found in most fruits, honey and some vegetables but not all foods that contain fructose need to be avoided. How well fructose is absorbed depends on the concentration of other kinds of sugars in the food such as glucose, sucrose and sorbitol. ? Glucose and dextrose can improve absorption especially if there in more glucose than fructose (a high glucose to fructose ratio). ? Sucrose (cane sugar) is broken down during digestion into equal amounts of glucose and fructose and may be tolerated in small amounts. However, large amounts of sucrose will release too high a total load of fructose. ? Sorbitol is a sugar alcohol found in some fruits and is often used as a sweetener. Sorbitol will usually decrease fructose absorptions and worsen symptoms. Dietary Treatment In some cases simply cutting out fruit juice may be enough to alleviate symptoms. For infants, whole or mashed/pureed fruit is recommended instead of juice. Fruit juice intake should be no more than about half a cup per day and diluted with water. Some people will need to limit to avoid common problem foods to control symptoms. Very sensitive people may require even greater restriction of fruit and vegetables if symptoms persist. Common Problem Foods The following are either high in total fructose content, contain a higher ratio of fructose compared to glucose or contain significant amounts of sorbitol or fructans. Fruit – apple, cherry, grape, guava, honeydew, lychees, mango, paw paw, persimmon, pear, quince, watermelon, large amounts of dried fruit or fruit juice, foods containing apple or pear concentrate, large amounts of stone fruit. Vegetables – artichoke, asparagus, chicory, leek, onion, spring onion, tomato paste Coconut milk and cream Honey Foods with a high fructose corn syrup Large amounts of high sugar foods such as soft drinks, cordials and confectionary Large amounts of wheat Extra Tips Fructose and sorbitol may be found in some medications. Inulin and fructo-oligo-saccarides, both sources of fructans, are sometimes added to foods such as yoghurt. Finding Tolerance Level Fructose tolerance is dose dependant and small quantities may not cause symptoms. After an initial low fructose diet for 4-6 weeks, fructose foods may be slowly re-introduced to find tolerance level. As fructose can take up to 3 days to pass through the digestive tract, start by trying a small amount of a “problem food” every four days. If this is ok, try having it more frequently, and then build up the quantity. Cut back if symptoms start to recur.
