When eating, you should pay attention to eating three meals a day to be 70% full. Eat smaller meals more often. Do not eat overly sweet foods or fishy and spicy foods. Smoking, drinking and other bad habits are strictly prohibited, because these will aggravate the condition. With diabetes, those who have the habit of smoking should quit smoking slowly within a year, rather than quitting all at once. People who have been taking hypoglycemic Western medicine for more than half a year should not stop taking it suddenly, because this will cause a sudden rise in blood sugar. They should slowly reduce the dosage under the guidance of a doctor until they stop taking it. In terms of diet, you should pay attention to eating a combination of coarse and fine grains.
