Children with a greater number of healthy food outlets near their homes had a reduced likelihood of being overweight or obese, finds a study. Children who had access to at least one healthy food outlet within 800 meters (about half a mile) of their home had a 38 percent decreased risk of being overweight or obese compared to those who did not. Each additional outlet for healthy foods within that distance was associated with a 19 percent reduction in risk of being overweight or obese.
