As a dietitian, I know that people with diabetes need to pay special attention to their daily dietary choices to avoid affecting blood sugar control and health. In this article, I will share some foods that diabetics should not consume, and explain the scientific principles in them, hoping to help more patients adjust their diet correctly and improve their quality of life. 
1. High-sugar foods First of all, for diabetics, high-sugar foods are one of the foods that should be kept away. High-sugar foods can quickly raise blood sugar levels, increase the burden of insulin, and increase the risk of cardiovascular disease and obesity if consumed over time. Therefore, diabetic patients should avoid high-sugar foods such as sweets, desserts, and sugary drinks, and choose low-sugar or sugar-free alternatives. 2. High-salt foodsHigh-salt foods are also bad for diabetics. Excessive salt intake increases the risk of diseases such as high blood pressure, heart disease, and kidney damage. Diabetic patients should avoid high-salt foods such as processed foods, pickled products, and instant noodles, and choose fresh ingredients to cook and reduce the use of salt to control salt intake. 
3. High-fat foodsHigh-fat foods should also be consumed with caution for diabetics. High-fat foods can easily lead to dyslipidemia and increase the risk of cardiovascular disease. Diabetics should avoid high-fat foods such as fried foods, fatty meats, butter, etc., and instead choose foods rich in healthy fats such as vegetable oils and fish as alternatives. 4. High-calorie foodsHigh-calorie foods can increase the weight of diabetic patients, which in turn affects blood sugar control and disease progression. Therefore, diabetic patients should avoid high-calorie foods, especially high-calorie, high-fat foods such as fried foods and desserts. Controlling your calorie intake and following the principles of moderation, variety, and balance is the key to maintaining good health. 5. Drinking alcohol and alcoholic beveragesFinally, diabetic patients should be cautious about drinking alcohol and alcoholic beverages. Alcohol affects the liver's regulation of blood sugar, affects the secretion and utilization of insulin, and easily leads to blood sugar fluctuations. Diabetic patients are advised to limit alcohol consumption or choose low-alcohol beverages, and pay attention to drinking alcohol with moderate amounts of food to slow down the effects of alcohol on blood sugar. 
Diabetic patients need to pay attention to the rationality and diversity of their diet, and avoid eating foods high in sugar, salt, fat, calories and alcohol to keep blood sugar stable and control the progression of the disease. Reasonable diet structure and scientific nutrition are an important part of the daily management of diabetic patients, I hope the above sharing will be helpful to the majority of patients, I wish you good health and a happy life!
