BOSTON, May 24 (UPI) -- U.S. teens underestimate the calories of their fast-food meals by about one-third but parents also underestimate fast-food meal calories, researchers say.
Lead researcher Dr. Jason Block of the Harvard Medical School/Harvard Pilgrim Health Care Institute colleagues surveyed nearly 3,400 adults, teens and school-age children in 2010 and 2011 at 89 fast-food restaurants in four New England cities.
