There is no such thing as a “contraindication to eating maltose”. The general public can eat a moderate amount of supplemental nutrition, but diabetics try not to eat. Maltose is a food, food does not have the toxicity of drugs, so there is no so-called contraindication. It is widely used in the food industry for the production of candy, juice drinks, cookies, wine, canned food, soy sauce, etc. It is a disaccharide, which can be quickly absorbed by the body to replenish the body’s sugar needs. As a result, the glycemic index of maltose is very high, in the case of insulin resistance or insufficient insulin secretion, it can rapidly increase blood sugar, so diabetic patients, especially severe diabetic patients try to eat less or do not eat maltose. Healthy people eating maltose also need to control the amount, long-term over-eating may lead to excessive sugar and energy intake, increasing the risk of obesity. It is recommended to achieve a balanced diet in life, scientific matching of food, and maintain a good lifestyle.
