The impact of household food consumption upgrading on the self-rated health of rural residents: evidence from China
摘要
Despite the inevitable trend of dietary diversification, the relationship between food consumption patterns and health in rural households has been significantly overlooked. Based on data from 2654 valid rural residents in the 2020 China Rural Revitalization Survey (CRRS), this study employs a binary Logit regression model to examine the relationship between food consumption upgrading and self-rated health among rural residents. The findings reveal that the upgrading of dietary structure has a significantly positive impact on rural residents’ self-rated health, mediated through four pathways: reducing the livelihood of chronic disease, increasing life satisfaction and happiness, and improving relative economic status. Additionally, household drinking water safety and frequency of physical exercise play positive moderating roles in this process. The health effects exhibit significant heterogeneity across regional, household and individual dimensions. Furthermore, the study identifies a potential inverted U-shaped relationship between household food consumption upgrading and rural residents’ self-rated health, with the estimated turning point of food consumption upgrading calculated at 39.92%. Therefore, in the pursuit of rural revitalization and sustainable development goals, it is imperative to prioritize rural residents’ food consumption patterns, while ensuring drinking water safety and improving physical activity infrastructure to maintain the health benefits derived from improved dietary quality.
