Diabetics can eat maltitol in moderation. Diabetes mellitus is a disease caused by abnormal insulin secretion and/or utilization, which is often clinically manifested as high blood sugar, increased food intake, weight loss, increased water intake and increased urine output. Maltitol is a sweetener whose molecular structure does not stimulate insulin secretion and has less blood glucose elevation after consumption. Diabetic patients can eat maltitol, but should pay attention to the right amount. The sweetness of maltitol can be close to ordinary sucrose, the human body has a low absorption rate of it, 90% of its components will be decomposed under the action of bacteria in the colon, and the calorie is very low. Diabetic patients are advised to arrange their diets under the guidance of their doctors.
