title: Consumption of sugar-sweetened beverages and discretionary foods among US adults by purchase location.
abstract: Excess calorie intake from sugar-sweetened beverages (SSBs) and energy-dense, nutrient-poor foods occupies a significant proportion of Western diet. The aim of this study was to examine consumption of SSBs and discretionary foods in US adults by purchase location.
  
  
  
  Nationally representative 24-h dietary recall data came from the 2011-2012 National Health and Nutrition Examination Survey. The discretionary food category identifies energy-dense, nutrient-poor foods that do not necessarily contain essential nutrients but may add variety and enjoyment. Linear regressions were performed to estimate daily calorie intake from SSBs and discretionary foods by purchase location (supermarket/grocery store, convenience store, vending machine, fast-food restaurant, full-service restaurant and other source), adjusting for individual characteristics and sampling design.
  
  
  
  During 2011-2012, 46.3% and 88.8% of US adults consumed SSBs and discretionary foods on any given day, respectively. SSB consumers on average consumed 213.0 kcal from SSBs daily, of which 111.6 kcal (52.4%) were purchased from supermarkets/grocery stores, 33.0 kcal (15.5%) from fast-food restaurants, 23.9 kcal (11.2%) from convenience stores, 17.1 kcal (8.0%) from full-service restaurants, 8.5 kcal (4.0%) from vending machines and 19.0 kcal (8.9%) from other sources. Discretionary food consumers on average consumed 439.0 kcal from discretionary foods daily, of which 280.1 kcal (63.8%) were purchased from supermarkets/grocery stores, 45.8 kcal (10.4%) from fast-food restaurants, 30.0 kcal (6.8%) from full-service restaurants, 21.1 kcal (4.8%) from convenience stores, 4.1 kcal (0.9%) from vending machines and 58.0 kcal (13.2%) from other sources.
  
  
  
  Supermarkets/grocery stores were by far the single largest source for SSB and discretionary food purchases in US adults.
