Approaches to solve Zn deficiency in human body

Zinc(Zn) is an essential micronutrient for human body, and zinc deficiency has become a widely spread micronutrient malnutrition problem for human beings. There are some traditional methods for zinc supplying, e.g. taking nutritional supplements, adjusting diet structure and adding zinc in food. However,these traditional methods have their own limitations. Biofortification of zinc in food, as a new method for zinc supplementation, has become a hotspot in this field. Rice, a second predominant staple food, has been widely used for zinc biofortification. In this paper, traditional zinc supplementation and biofortification of zinc in rice are summarized and discussed. Through improving agronomic management, in particular increasing micronutrient fertilizer application to improve the zinc content in the plant is considered to be an effective way to improve human zinc nutrition. This paper analyzed the present situation of human zinc supplementation approach,and elaborated the characteristics of agronomic measures to realize zinc enrichment in agricultural commodities rice. In the future, the related research should be focused on the establishment of relevant standards and the development of applied products. It should be studied in a much more systematic way, and promote the development of micronutrient rich agricultural products and food industry in a healthy way.
