As long as it is a local specialty suitable for eating, it has the effect of health care. Usually eat more, even a little more. Eating organic pollution-free rice is different from eating rice grown with pesticides and herbicides. Carefully calculate how much rice a person can eat a year, how much it costs to buy good rice and how much it costs to cure diseases. Not afraid doesn't count, just count. My habit is to go to the morning market every day. When I see mountain products in season, I buy some fresh and pollution-free vegetables, which is very comfortable.
