Buddhism advocates vegetarianism, but it does not prohibit lay people from eating meat. At home, lay people hold the five precepts, don't kill anything, and eat three clean meats. Vegetarianism is purely voluntary, and beginners don't have to force it. It's never too late to be a vegetarian when the time is right.
In addition, in modern medicine, long-term vegetarian diet may lack vitamin b 12, because vitamin B 12 only exists in animal meat. The content in plants is very small. For vegetarians, please search for "vitamin B 12" on the Internet to understand the symptoms of vitamin B 12 deficiency, so as to supplement it in time and ensure good health, which is the capital of spiritual practice. ,
