Sorbitol is an alditol and resembles fructose in its chemical structure. It is commonly used as a sugar substitute in calorie-reduced products; it is also contained almost without exception in all tooth-pastes. High concentrations of sorbitol are also found in some fruit, e.g. in prunes or cherries.

Sorbitol is to be avoided if you suffer from Fructose Intolerance and, as a rule Fructose Malabsorption goes together with sorbitol intolerance.
