When people eat health porridge, the food they eat is digested and absorbed by the spleen and stomach, and the nutrients are transported into the five zang-organs and turned into the essence of the viscera, so that the viscera are full of essence. Then the essence will be further stored in the kidney. When the five internal organs need nutrition, the kidney will transport the stored essence to the five internal organs, thus circulating the supply and storage of the kidney and maintaining daily life activities.

When it comes to health, we must first tonify the kidney. There is a saying that "kidney stores essence". Kidney has the function of storing essence and is the original substance that constitutes the human body. People have vital signs because kidney essence is the material basis. To nourish essence, diet conditioning is a good method. Health porridge in diet is the top grade in dietotherapy, so you should eat more at ordinary times.
