Analysis of the Influence of Dietary Pattern on the Health Level of Residents in China

We used the DEA cross-efficiency method to explore the health effects of provincial differences in dietary patterns in China. The result showed that for the group aged 0-14, Inner Mongolia and Guizhou provinces rank the top, and children in Zhejiang province should add more dairy products and eggs in the diet; For the group aged 15-64, there are fewer differences between provinces, but it generally shows high calorie and high protein intake among them; For the group aged over 64, Shanghai and Tianjin provinces are low-ranking, and old people in Shanghai province should reduce the egg intake while those in Tianjin province should have more vegetable and meat intake.
