Wal-Mart may contribute to obesity with its low prices on packaged foods, but the choice of location for Wal-Mart Super Centers helps increase the availability of calories, which means poor children and families are less likely to go hungry. Middle-income families also have greater food security when Wal-Mart moves into the neighborhood. Interestingly, Wal-Mart Neighborhood Markets do not have the same effect.
