This study leverages smartphone data from 1,164,926 MyFitnessPal users to investigate the relationship between food environment and diet in the US. The researchers found that greater grocery store access, less fast food access, higher income, and higher education were associated with healthier diets (more fruits and vegetables, less fast food and soda, lower obesity). However, these associations varied significantly across zip codes with predominantly Black, Hispanic, or white populations, highlighting the need for targeted interventions.
