If you have been diagnosed with fructose-digestion disorders, avoid foods that contain fructose, sucrose and sorbitol. If you suspect that fructose intolerance is a problem, avoiding all fructose for a week or so should cause a reduction in symptoms, if this sugar is causing them. If symptoms are reduced, reintroduction of fructose should lead to a recurrence of the original symptoms.
Sources of fructose include confectioner’s sugar; fruit juice; fruits; honey; sodas; sports drinks; milk that has been sweetened; flavored waters; and anything that contains high-fructose corn syrup (HFCS). HFCS is added to many items, so one must learn to read labels carefully.
