Zinc is one of the essential trace elements for human body and it plays an important role in a variety of human physiological processes. People who take cereals with low zinc content and low zinc bioavailability as the main dietary structure often have insufficient zinc intake, which causes zinc deficiency in human body and affects human health. Biofortification engineering is an agronomic measure based on modern biological breeding technology and fertilizer application to increase the zinc content in grains of cereal crops and increase the level of dietary nutrition. The researches on zinc fertilizer application, zinc absorption and accumulation in crop grains, and human zinc intake and human health are reviewed. The significance of reasonable application of zinc fertilizer to improve human zinc nutrition is discussed.
