Geographic Accessibility Of Food Outlets Not Associated With Body Mass Index Change Among Veterans, 2009–14. Shannon Zenk et al. Health Affairs, August 2017, vol. 36 no. 8 1433-1442, http://content.healthaffairs.org/content/36/8/1433.short
Abstract: In recent years, various levels of government in the United States have adopted or discussed subsidies, tax breaks, zoning laws, and other public policies that promote geographic access to healthy food. However, there is little evidence from large-scale longitudinal or quasi-experimental research to suggest that the local mix of food outlets actually affects body mass index (BMI). We used a longitudinal design to examine whether the proximity of food outlets, by type, was associated with BMI changes between 2009 and 2014 among 1.7 million veterans in 382 metropolitan areas. We ***found no evidence that either absolute or relative geographic accessibility of supermarkets, fast-food restaurants, or mass merchandisers was associated with changes in an individual’s BMI over time***. While policies that alter only geographic access to food outlets may promote equitable access to healthy food and improve nutrition, our findings suggest they will do little to combat obesity in adults.

My commentary: We should stop saying things that we suspected were not true and now we know (1.7 million veterans studied) are not true. Being close to or passing by junk food outlets is not causing obesity...
