The general population will not have elevated blood sugar when drinking yogurt because insulin in the body maintains blood sugar at a relatively constant state, causing it to fluctuate within the normal range. Diabetics may not have elevated blood sugar if they simply drink unsweetened yogurt, but if the yogurt contains sugar, it may raise the blood sugar of diabetics. Insulin secretion in diabetic patients is not secreted on demand, and insulin secretion may lag behind the peak blood glucose concentration, so diabetic patients drinking yogurt with sugar may cause blood glucose fluctuations, and it is recommended not to drink yogurt with sugar. Yogurt is rich in protein and calcium. It is recommended for diabetics to drink sugar-free yogurt directly to supplement the body with nutrients while maintaining blood sugar balance. In addition, in the daily diet, diabetic patients should eat mainly whole grains as the main food, more green leafy vegetables, such as spinach, celery, etc., and as little oil and salt as possible. Pay attention to drink less rice porridge, because the starch part will be broken down into carbohydrates, which are more easily absorbed, thus raising blood sugar.
