Tell me when people started to be vegetarians and why.

I am a vegetarian, healthy and have good skin. I should eat vegetarian food in a balanced way. Whole grains, such as millet porridge and brown sugar, regulate qi and blood and make me red. Black rice porridge, red bean and barley porridge. Nuts are two walnuts a day, and red dates can cook porridge and eat more than five. You can't eat anything when you are sick, such as frying, milk tea and drinks. In particular, animal meat and seafood are hormones, which are easy to get sick.
