In view of the inevitability of death, human beings typically reach toward immortality by ”keeping in good health.” Although the culture of maintaining health is not the main thought in ”The Confucian Analects,” several pertinent points appear in 10.7 ('Xiangdang'). It is noteworthy that Kong Zi [Confucius] lived a long life without the type of medical care considered minimum by modern standards. Since good health begins with good nutrition, a discussion of dietary habits (i.e., eating the right foods in the right way) is quite appropriate. The aim of this study was to analyze Kong Zi's dietary perspective, as detailed in 10.7, and seek verification of his principles in modern preventive medicine.
