Diabetic patients can eat bitter melon because it contains less than 4% sugar, which is a vegetable with low sugar content. 100-200g of bitter melon is appropriate for each serving. The specific benefits are as follows: 1. Bitter melon is rich in dietary fiber and vitamin C, which is beneficial to the health of diabetic patients; 2. Bitter melon also contains bitter melon glycosides and proteins with insulin-like functions, which can convert glucose in the blood of diabetic patients into calories and has a good hypoglycemic effect. Diabetic patients can choose vegetables with low sugar content, such as vegetables with sugar content below 4%, including cabbage, chard, celery, eggplant, spinach, leek, bitter melon, cucumber and tomato.
