Does vegetarianism affect your health? Is eating vegetarian food related to religious belief?

I think vegetarianism is an attitude towards life, which has nothing to do with food or belief. Vegetarianism is to minimize our physical contact with the outside world and achieve a basic balance. Instead of getting extra heat on the one hand and trying to vent it on the other. Restrain yourself, you can get inner satisfaction, and you can also minimize the interference to the outside world. Why not?
