Glucose is not recommended for diabetics, but can be eaten when hypoglycemia occurs. Glucose is a monosaccharide, which is quickly absorbed by the body after consumption and rapidly enters the bloodstream resulting in increased blood sugar levels, leading to large fluctuations in blood sugar, which is not conducive to blood sugar control in diabetic patients. However, when a diabetic patient experiences hypoglycemia with symptoms such as dizziness, panic, sweating, and hunger, he or she can immediately eat glucose, which raises blood sugar quickly and can correct hypoglycemia. Diabetic patients should choose low-salt, low-fat, low-sugar foods, try to choose foods with low glycemic index, such as a variety of green leafy vegetables, coarse grains and beans, etc., and consult a professional endocrinologist or dietitian to formulate an individualized dietary plan if necessary.
