Food should be diversified and basic. Vegetarian food contains essential sugar, protein, fat, minerals and rich vitamins, which plays an important role in delaying aging, preventing senile diseases and improving health. Vegetables and fruits are alkaline foods, while grains, beans, fish and eggs are acidic foods.

People usually eat more acidic food, which is easy to cause acid-base imbalance in the body and harmful to the body. Vegetarian food is very beneficial to human health, but eating more vegetarian food does not mean not eating vegetarian food. Reasonable diet conditioning should be based on vegetarianism and combined with vegetarianism in order to prolong life.
