Fructose and sorbitol are two sugars that often are added to processed foods and medications to make them taste sweet. Fructose can be found in soda pop and many fruit juice drinks. Sorbitol is found in diet products, chewing gum, candy, Popsicles, and some medications (such as syrups for fevers and colds). Sometimes sorbitol and fructose are added to the same product.

Gas, abdominal bloating and pain, and diarrhea are common symptoms of fructose or sorbitol intolerance.
