For diabetics, there is no such thing as absolutely no food, except for foods that can clearly trigger allergies, only that high sugar, high salt and high fat foods should be eaten sparingly. It is recommended that diabetic patients choose low-sugar, low-salt and low-fat foods, such as green leafy vegetables and coarse grains. In general, foods with a high glycemic index, such as rice, steamed buns and noodles made from refined rice and flour, should be reduced in moderation, and yams, sweet potatoes, potatoes, buckwheat, black rice and other foods with a relatively low glycemic index can be used to replace a portion of the staple food. Meat in the chicken, duck and fish can be appropriate to eat more, pork, beef and lamb lean meat can be eaten in small quantities; a variety of fresh vegetables and low-sugar fruits can be eaten almost all. After suffering from diabetes, it is best to adjust the diet under the guidance of a doctor or dietitian, do not blindly believe in the so-called taboo, to avoid leading to unbalanced nutrition.
