Dietary control is the foundation of diabetes treatment. Certain foods should be eaten sparingly or not because of their ability to rapidly raise blood sugar or cause chronic complications of diabetes. Knowing these foods and paying attention to them in your diet can help improve blood sugar control and reduce the development of diabetic complications. Lulu Chen of the Department of Endocrinology, Wuhan Union Hospital, diabetic patients should not eat white sugar, brown sugar, rock sugar, glucose, maltose, chocolate, milk sugar, fruit sugar, preserves, canned fruit, soft drinks, fruit juice, jam, ice cream, sweet drinks, sweet cookies, sweet bread and sugar pastries. The above foods are high in monosaccharides or disaccharides, and diabetic patients are prone to hyperglycemia after eating them. Peanuts, melon seeds, cashew nuts, pine nuts, walnuts, which contain high calories, should not be eaten frequently. Foods with high sugar content such as vermicelli, sweet potatoes, potatoes, taro, corn, rhizome, chestnuts, mao beans and other dried beans should not be used as vegetables for diabetics. As a side dish, the supply of staple foods should be reduced. And the quantity should be limited. Diabetic patients should not eat cholesterol-rich food and animal fat, such as animal brain, liver, heart, lung, waist, egg yolk, fatty meat, butter, pork and beef lamb oil, etc., and eat less fried, deep-fried, fried and crispy food, because the above foods tend to raise blood lipids, leading to increased incidence of atherosclerosis and cardiovascular diseases. Excessive alcohol can cause disorders of lipid metabolism and increase the burden on the liver; long-term alcohol consumption can increase the incidence of diabetic complications; drinking alcohol on an empty stomach can cause hypoglycemia in people who inject insulin. Therefore, diabetic patients should not drink alcohol. If you want to drink alcohol, you can drink a small amount of beer with low alcohol concentration. 400 ml of beer provides about 112 kcal of caloric energy, which is equivalent to 30 grams of grain, and you should subtract this part from your main diet accordingly. The diet should be light, not too salty, and reduce the consumption of processed or preserved foods to prevent excessive sodium intake, as high sodium can easily induce hypertension and atherosclerosis.
