Diabetes is not a lifelong inability to eat good food, but usually refers to the need to control the amount of food in future diets. A lack of insulin in a diabetic patient’s body reduces the ability of the cells to take up glucose, which leads to an increase in blood glucose. If blood glucose is not well controlled and the body is left in a prolonged hyperglycemic condition, it can lead to a series of complications, which may even be life-threatening in severe cases. Diabetes is treated in five ways: health education, exercise, diet, blood glucose monitoring, and medication. Dietary treatment refers to the need to control the amount of food in the future, some high-sugar foods need to eat less or not eat, so diabetes is not a life-long can not eat food, but to eat some restrictions. Diabetic patients are recommended to rationalize the diet under the guidance of the doctor.
