Huangdi Neijing pointed out that "healthy qi should be kept inside, and pathogenic factors should not be done", indicating that the human body is full of healthy qi, and pathogenic factors cannot invade and make people sick. To be healthy and energetic, it is necessary to arrange diet reasonably, so as to ensure the nutrients needed by the body and the functions of the five internal organs can be vigorous. Modern medicine has proved that if the human body lacks certain food ingredients, it will lead to diseases, such as rickets caused by calcium deficiency, night blindness, beriberi, stomatitis, scurvy and rickets caused by vitamin deficiency.
