Go to bed early and get up early every day, and exercise for an hour every day, because good health is made by exercise, not by eating. Exercise can make your blood circulation smooth and your immune function regulated. Second, you must eat vegetables and drink yogurt every day, because vegetables are rich in vitamins and can supplement a variety of nutrients. Yogurt is rich in lactic acid bacteria, which can moisten the intestines after drinking. These two foods can be eaten more. Third, drink more water and eat more beef and mutton, because these meats are safe compared with pork, because pork now is either lean meat or hormones.
