Buddhism says don't eat meat, because eating meat is killing life, destroying life and showing unkindness. People who eat meat have no relationship with Buddha. There is also a view that the meat you eat may be the meat of your parents and relatives, because it may be the reincarnation of your parents and relatives, so you must not eat it. Later, according to the living conditions of lay people at home, Buddhist scholars suggested that they could eat "three clean meats", that is, "don't kill for me"; I don't kill people; You can eat the meat you killed without looking. That is to say, the meat you eat is not slaughtered by others, you don't kill animals, and you can eat them without watching them be killed.

Vegetarianism is an important part of Buddhist health preservation. Buddhism is called vegetarian, that is, it doesn't eat meat. Perhaps many people think that it is impossible to be healthy without eating meat, but after research, it is found that eating vegetarian food is more beneficial to health.
