Being a Buddhist vegetarian at home is different from becoming a monk. It has many worldly affairs and consumes a lot of energy. You can eat more milk, honey, fungus, tofu, peanuts, fruits and other supplementary nutrition. A long-term single vegetable may lack nutrition, so it is necessary to improve the diet structure, but it is not necessary to ask him to change his beliefs and eat meat.
People who like to eat fish for a long time should pay more attention. At present, chickens, ducks, fish and pigs are all fed with hormones, and the abuse of antibiotics in feed is an open secret. Might as well eat less.
Medical evidence shows that housekeepers who are vegetarian for a long time may lack vitamin B 12 and L-carnitine. Please search these two vitamins online.
