A main motivation is the health of school children, and, in particular, the rising childhood obesity rate. Medical and nutrition literature has long argued that a healthy diet can have a second important impact: improved cognitive function. In this paper, we test whether offering healthier lunches affects student achievement as measured by test scores. Our sample includes all California (CA) public schools over a five-year period. We estimate difference-in-difference style regressions using variation that takes advantage of frequent lunch vendor contract turnover. Students at schools that contract with a healthy school lunch vendor score higher on CA state achievement tests, with larger test score increases for students who are eligible for reduced price or free school lunches. We do not find any evidence that healthier school lunches lead to a decrease in obesity rates.  \nMichael L.

A primary motivation underlying these nutritional improvements is to increase student health and reduce childhood obesity rates. A question of comparable import, however, is whether healthier meals a􀀋ect student achievement. Recent research demonstrates that the provision of subsidized school meals can signi􀀌cantly increase school test scores (Figlio and Winicki [2005]; Dotter [2014]; Imberman and Kugler [2014]; Frisvold [2015]), but to date little evidence exists on how the quality of school meals a􀀋ects student ac","cbCaioSUDXbZ09b3","https://ap.wps.com/l/cbCaioSUDXbZ09b3","pdf",740345,47,"English","# Abstract\n# Introduction\n## Research question and policy motivation\n## Data and empirical strategy\n## Measuring nutritional quality","[{\"question\":\"What is the main research question of the paper?\",\"answer\":\"The paper tests whether healthier school lunches affect student achievement as measured by academic test scores.\"},{\"question\":\"How does the study identify the effect of lunch quality?\",\"answer\":\"It uses difference-in-differences style regressions based on variation from frequent lunch vendor contract turnover across California school districts.\"},{\"question\":\"What nutritional quality measure do the authors use?\",\"answer\":\"They measure lunch nutritional quality with an enhanced Healthy Eating Index (HEI) score based on how well food offerings align with the Dietary Guidelines for Americans.\"}]","School Lunch Quality and Academic Performance - Working Paper 23218 | PDF",118]
