Zhou Li Tianguan said: "Where there is harmony, spring is sour, summer is bitter, autumn is bitter, winter is fruitful, and there is smooth and sweet." There is nothing wrong with the balance of yin and yang in human body. Because people love fat, sweet, spicy and bitter in diet, it often leads to excessive yang and insufficient yin, so we should eat some bitter food all year round, especially in summer.
In summer, the human body needs a lot of vitamin C. If you put some vinegar in cooking, it will not only be delicious, but also protect vitamin C. In addition, in hot summer, family members like to eat cold dishes and cold noodles. If you put some vinegar when eating noodles, it will greatly increase people's appetite, help digestion, and play a role in sterilization, detoxification and prevention of intestinal infectious diseases.
