Replacing calorie-dense snack foods with calorie-sparse fruits and vegetables can be one step in addressing childhood obesity and does not have to compromise a family’s food budget. An ERS analysis of prices per portion for 20 common snack foods and 20 potential fruit and vegetable substitutes found that 9 of the 20 fruits and vegetables and 8 of the 20 snack foods cost 25 cents per portion or less; an additional 8 fruits and vegetables and 10 snack foods cost between 26 and 50 cents per portion. On average, the 20 fruits and vegetables cost 31 cents per portion and the 20 snack foods cost 33 cents per portion. A household making all possible 400 substitutions between the 20 snack foods and the 20 fruits and vegetables would save an average of 2 cents and 126 calories per swap. The statistics in this chart are from "Gobbling Up Snacks: Cause or Potential Cure for Childhood Obesity?" in the December 2012 issue of ERS’ Amber Waves magazine.
