Abstract: Circadian clock is timing mechanism, it is an invisible “clock” in the organism, and it is actually an organism inner rhythm of life activity. It is determined by the time sequence structure in the organism. It keeps the periodicity in the internal circulation of behavior, physiology and metabolism, and in sync with the external environment. In this paper, the circadian system, the regulation genes of circadian clock, the regulation of biological clock on nutrient metabolism and digestive organs, and its application in practical production are reviewed.

Key words: biological rhythm, circadian clock, nutrition metabolism, nutritional regulation
