Shoppers aren’t the only ones looking for grocery store coupons and discounts. Public health researchers hope to find ways to curb overweight and obesity rates by studying how price breaks on food affect consumer choices for high- and low-calorie foods.
Investigators recently analyzed 6493 food purchases involving 2223 price discounts at a Philadelphia supermarket in 2010 and 2011. Shoppers were nearly 6 times more likely to buy sweet snacks or grain-based snacks and 2.6 times more likely to buy sugar-sweetened beverages when these were on sale rather than sold at full price (Phipps EJ et al. Prev Chronic Dis.doi:10.5888/pcd11.140174 [published online September 4, 2014]).
