Diabetics have the advantage of eating potatoes in moderation because they contain a large amount of dietary fiber, which can slow down the absorption of glucose in the body, and dietary fiber can also affect the absorption and conversion of fat. Because of the high starch content of potatoes, so diabetics are not easy to eat too much. Potatoes also contain a lot of vitamins, inorganic salts, magnesium, and potassium, which is needed for glycogen and protein synthesis in the body and plays an important role in maintaining cellular metabolism. In addition, potatoes can also slow down the rise of blood glucose in diabetic patients, which can lead to excessive insulin secretion in the body, thus effectively helping diabetics to reduce their food needs. Since potatoes contain fiber that can increase satiety and laxative effect, diabetic patients can benefit from eating potatoes in moderation.
