To control blood sugar, we need to eat less fatty foods and limit the intake of carbohydrate-based foods. Foods that contain less fat and absorbable carbohydrates can help control blood sugar. Milk, lean meat, fish and shrimp, eggs, tofu and other foods are rich in protein, and the content of carbohydrates is relatively low, suitable for diabetics, but not more than 1 tael per meal. Vegetables such as cabbage, cucumber, eggplant, etc. do not contain fat, and the ingredients are mainly fiber and vitamins that can effectively control blood sugar, and Chinese herbs such as yam and wolfberry, which are used to treat diabetes, can also be consumed. Fruits such as apples, grapefruit and oranges have a low glycemic index and can be consumed in moderation to help control blood sugar. Lychee is rich in fructose and can be consumed appropriately as it does not raise blood sugar significantly after consumption.
