If the fasting blood glucose is 6.4mmol/L, it is recommended to control the amount of rice intake, and if the 2-hour postprandial blood glucose is 6.4mmol/L, you can consume rice normally. Clinically, the normal value of fasting blood glucose is 3.9-6.1mmol/L, and the normal value of 2-hour postprandial blood glucose is less than 7.8mmol/L. When the value of fasting blood glucose is 6.4mmol/L, it is in the high state, and you can control blood glucose by controlling the diet, and you can consume rice appropriately in daily life, and you need to control the amount of intake under the guidance of the doctor, and the 2-hour postprandial blood glucose is normal.
