Over the past few decades，significant changes have occurred in the relationship between food supply and demand in China and the concept of food security has gradually shifted from the traditional emphasis on grain security to a multi-target approach focusing on quantity，nutrition and sustainable development，known as the Greater Food Approach.Under this approach，China will face many challenges in balancing food supply and demand in the future，including structural food shortages and declining food self-sufficiency；spatial mismatch between food supply and demand，and significant differences in food consumption among different groups of people；increasing constraints on ecological and water resources，and the urgent need to enhance sustainable production capacity.Additionally，there are issues related to unbalanced dietary patterns and the coexistence of malnutrition，excessive nutrition，and deficiencies in micronutrients.Furthermore，the existing policy systems does not fully meet the requirements of the Greater Food Approach.To address the above challenges，it is necessary to comprehensively utilize national resources，increase food sources through multiple channels，reform government subsidy and support policies，and promote the development of the diversified food industry.Simultaneously，efforts are required to strengthen food education and publicity and to promote the establishment of a health-oriented diversified dietary pattern.The government should establish a cross-sectoral coordination mechanisms and strengthen the statistics and evaluation of diversified food supply.
