The key to a healthy diet is to have a reasonable diet structure. "Health Record" talks about the "six fitness" of health preservation, and we should eat early, warm, little, light, slow and soft. In terms of diet, Lu You, a poet in the Southern Song Dynasty, drank porridge.

He wrote in a poem: all the people in the world are predecessors, but they don't realize that many years are in the present; I had to follow the popular method and only give porridge to the gods.
