Abstract：
UNASSIGNED: Internet use is changing nutritional intake and health outcomes, but the results are mixed, and less attention is given to the rural developing regions. Based on the China Health and Nutrition Survey (CHNS) data from 2004 to 2015, this study seeks to better understand the effect of Internet use on nutritional intake and health outcomes.
UNASSIGNED: An instrumental variable estimation is used to address endogeneity problem.
UNASSIGNED: The results show that Internet use improves the dietary knowledge of rural residents, and thus has a positive impact on dietary quality, such as healthy eating index (HEI) and dietary diversity score (DDS). The higher the dietary quality, the better the nutritional health status. However, results also show that Internet use increases the risk of overweight, and obesity among rural Chinese residents. Because Internet use has significantly reduced the physical activity of rural residents in China. Interestingly, we also find that the Internet increases the risk of chronic diseases such as diabetes and high blood pressure, but there is a positive causal relationship between Internet use and the self-assessment score of health.
UNASSIGNED: Our findings suggest that there may be a serious lack of awareness of the health risks of chronic diseases among Chinese rural residents. Therefore, policymakers are suggested to consider the possible negative effects when promoting digital development.

摘要：
■互联网的使用正在改变营养摄入和健康结果，但是结果喜忧参半，对农村发展中地区的关注较少。基于2004年至2015年中国健康与营养调查（CHNS）数据，本研究旨在更好地了解互联网使用对营养摄入和健康结果的影响。
■工具变量估计用于解决内生性问题。
■结果表明，互联网的使用提高了农村居民的饮食知识，因此对饮食质量有积极的影响，如健康饮食指数(HEI)和饮食多样性评分(DDS)。饮食质量越高，营养健康状况越好。然而,结果还表明，使用互联网会增加超重的风险，中国农村居民肥胖。因为互联网的使用显著降低了我国农村居民的体力活动。有趣的是,我们还发现，互联网增加了慢性疾病的风险，如糖尿病和高血压，但是互联网使用与健康自我评估评分之间存在正的因果关系。
■我们的发现表明，中国农村居民对慢性病的健康风险可能严重缺乏认识。因此,建议决策者在促进数字发展时考虑可能的负面影响。
