Usually diabetic diet is recommended to be cereal-based, high dietary fiber intake, low-fat and low-sugar diets are recommended, and reasonable diets under the guidance of a doctor. 1. Cereal-based. Whole grains and legumes are recommended as staple foods. Whole grains refer to grains that are not finely processed or treated. Mixed legumes refer to starch-rich legumes, including red beans, mung beans and other foods other than soybeans. 2. High dietary fiber foods. Because high dietary fiber food, to a certain extent, can promote intestinal digestion of food, generally can reduce the absorption time of sugar and lipids. 3. Low-fat and low-sugar diet. Patients with diabetes need to eat a low-fat and low-sugar diet, and reduce the intake of foods and fruits that are high in sugar. Dietary management for diabetic patients should receive professional guidance from an endocrinologist.
