Abstract: Rice is one of the most important food crops in the world, and about half of the world’s population uses it as the main food source. China’s annual rice output accounts for about 34% of the world’s annual rice output, ranking first in the world, thus China is known as the "Rice Kingdom". Rice has high nutritional value, providing the human body with 35% of the total energy intake and about 28% of the required protein. Therefore, the nutritional value of rice is directly related to human nutrition and health. In this paper, the three aspects of rice nutrition and human health, factors affecting rice nutritional quality and genetic improvement of nutritional quality of rice are reviewed. The new challenges of rice nutrition quality were analyzed, and the prospect of improving rice nutritional quality was prospected. The results provide theoretical basis for genetic improvement of rice nutrition quality and cultivation of new high-quality rice varieties in the future.
