People with diabetes should avoid or eat less maltodextrin. Maltodextrin is a nutritive polysaccharide that can be intermediate between amylose and starch, and is used as a filler and thickener in a variety of foods. Due to its high content of polysaccharides, consumption may cause postprandial blood glucose increase, and maltodextrin is also a food additive, so diabetic patients should eat less maltodextrin. In daily life, diabetic patients should maintain a low-salt, low-sugar, low-fat diet, do not recommend eating sweetened beverages, fried foods, fatty meats and other foods, increase fresh vegetables, fruits and other vitamin-rich foods, maintain appropriate physical activity, while cooperating with the doctor to actively treat.
