I provide new evidence on how price changes of nutritionally similar foods, such as those rich in sugar or fats, change obesity and diet-related diseases in the context of Mexico between 1996–2010. I merge a bar-code level price dataset with product-specific nutritional composition to two datasets with health outcomes: state-level administrative and nationally representative individual-level panel data. Exploiting within-city variation in prices using fixed effects models, I show that decreased prices of sugar-rich foods increase obesity, type 2 diabetes, and hypertension prevalence; yet the prices of foods rich in other nutrients do not. Health responses to price changes are the largest for those abdominally obese or at the highest risk for chronic disease. The association between prices of sugary foods and chronic disease is meaningful: I estimate that in Mexico, price reductions of sugary foods explain roughly 15 percent of the rise in obesity and diabetes during the 15-year study period.

我提供了新的证据，说明营养相似的食物（例如富含糖或脂肪的食物）的价格变化如何在 1996 年至 2010 年期间改变墨西哥的肥胖和与饮食相关的疾病。我将带有特定产品营养成分的条形码级价格数据集合并到具有健康结果的两个数据集：州级行政和具有全国代表性的个人级面板数据。使用固定效应模型利用城市内的价格变化，我表明，高糖食品价格下降会增加肥胖、2 型糖尿病和高血压的患病率；然而，富含其他营养素的食物的价格却没有。对于那些腹部肥胖或慢性病风险最高的人来说，对价格变化的健康反应是最大的。含糖食品价格与慢性病之间的关联是有意义的：
