Healthy diets and proper nutrition are fundamental for human survival. With economic development and rising incomes, the food consumption structure of rural residents in China has noticeably changed. However, substantial disparities still exist in the quality of food consumption between urban and rural areas, and the dietary structure of rural populations remains imbalanced. This study uses 2020 China Rural Revitalization Survey (CRRS) samples of rural residents for analysis since it asked residents questions about their digital literacy and food consumption. A total of 2827 valid rural resident samples were finally obtained, and the participants had a mean age of 54.844 years. This study employs the ordinary least squares (OLS) model and the two-stage least squares (2SLS) method to examine the impact of digital literacy on the food consumption structure of rural households and its underlying mechanisms. Based on the regression analyses, digital literacy significantly improves the food consumption structure of rural residents ( < 0.05). Heterogeneity analysis shows that at the regional level, digital literacy has a stronger impact on the food consumption structure of rural residents in southern China (β = -153.255, < 0.05); at the individual level, its impact is more pronounced among rural residents with lower educational attainment (β = -427.506, < 0.01) and among middle-aged and elderly populations (β = -212.705, < 0.05). The mechanism analysis reveals that digital literacy can enhance the food consumption structure of rural residents by increasing their awareness of dietary health and food safety. These findings highlight the necessity of integrating the optimization of food consumption structures with enhancements in digital literacy into policy-making and provides valuable insights for developing policies aimed at improving the nutritional health of rural residents.
健康的饮食和适当的营养是人类生存的基础。随着经济发展和收入增加，中国农村居民的食品消费结构发生了显著变化。然而，城乡之间在食品消费质量上仍存在巨大差距，农村人口的饮食结构仍然不均衡。本研究使用2020年中国农村振兴调查（CRRS）中农村居民的样本进行分析，因为该调查询问了居民有关数字素养和食品消费的问题。最终获得了2827个有效的农村居民样本，参与者的平均年龄为54.844岁。本研究采用普通最小二乘法（OLS）模型和两阶段最小二乘法（2SLS）来检验数字素养对农村家庭食品消费结构的影响及其潜在机制。基于回归分析，数字素养显著改善了农村居民的食品消费结构（<0.05）。异质性分析表明，在区域层面，数字素养对中国南方农村居民的食品消费结构影响更强（β = -153.255，<0.05）；在个体层面，其影响在受教育程度较低的农村居民（β = -427.506，<0.01）和中老年人群体（β = -212.705，<0.05）中更为明显。机制分析表明，数字素养可以通过提高农村居民对饮食健康和食品安全的认识来改善其食品消费结构。这些发现凸显了将食品消费结构优化与数字素养提升纳入政策制定的必要性，并为制定旨在改善农村居民营养健康的政策提供了有价值的见解。
