Abstract: When children enter puberty,they will experience prominent changes mainly in the morphology of their reproductive organs,and development of function and secondary sexual characteristics.The main manifestation of precocious puberty is the earlier development of secondary sexual characteristics and the premature maturation of sexual organs,which is an endocrine disease characterized by abnormal growth and development of children.With the development of economy and society,the advancement of the onset age of precocious puberty and the increase in incidence rate have triggered increasing social attention.Multiple factors can have an impact on precocious puberty,and modern researches have confirmed a correlation between the daily diet of children before puberty and precocious puberty.This article reviews domestic and foreign researches in common dietary patterns and various dietary nutrients related to adolescent sexual development in children,represented by high calorie diet patterns,Mediterranean diet patterns,and vegetarian diet patterns,and it summarizes the influence of different dietary patterns on precocious puberty in children.The article respectively summarizes the potential regulatory mechanisms of high protein diet,high-fat diet and high sugar diet in high calorie diet patterns,as well as the main dietary components (vegetables,fruits,olive oil,grains,nuts,beans,and dairy products) in Mediterranean diet patterns and vegetarian diet patterns in sexual development.The aim is to provide theoretical basis for the prevention and treatment of precocious puberty in children from the perspective of dietary intervention,and to provide new ideas for future researches on the relationship between dietary nutrition structure and sexual development.
