Kids gain weight when new convenience stores open nearby. A new study found that changes in the food environment around low-income and high-ethnic/racial minority populations over time impact childhood obesity. Increased availability of small grocery stores selling a selection of healthy items in close proximity to children's homes improves their weight status over time, whereas increased availability of convenience stores selling predominantly unhealthy foods is likely to be detrimental.
