Diabetes diet is the most important part of diabetes prevention and treatment. Without diet control, no other treatment can be successful. In the clinic, patients often ask: “Doctor, I have diabetes, what can I eat? What can’t be eaten? In fact, diabetic patients, there is no food absolutely can not eat, and there is no food can be free to eat. So, how should diabetics eat? First of all, the principle of our dietary treatment is to reasonably control the total calories, ensure adequate carbohydrate intake, control the fat intake, moderate protein intake and adequate dietary fiber. For those sugary drinks, sucrose, glucose, ice cream, etc., which can raise blood sugar in the short term, unless in hypoglycemia, usually should try not to eat, and things containing a lot of fat such as cream, butter, lard and nuts such as melon seeds, peanuts, pecans, etc., should also be eaten as little as possible. How do diabetics eat fruit? As the sugar content of fruits is generally between 6-25%, when the patient’s blood sugar is not well controlled, try not to eat them. When in the case of good blood sugar control, 25 grams of staple food can be used to replace about 200 grams of fruit, when eating fruit at the same time to reduce the corresponding amount of staple food, the best time to eat fruit between meals or before bed, and try to avoid eating fruits with high sugar content such as sugar cane, grapes, etc. The meals of diabetic patients are required to be regular and quantitative, generally three meals a day, for patients who inject insulin or patients with frequent hypoglycemia, in addition to three regular meals, it is better to have 2-3 additional meals, the additional food must be the food within the total calorie range, not additional food, can be absorbed from the main food of 1/4-1/5, or milk or fruit.
