November 20/Philadelphia/HealthDay News -- The energy content of U.S. fast-food restaurant lunch and dinner menu items has changed little over a 14-year period from 1997 to 2010, according to a study published in the November issue of the American Journal of Preventive Medicine.
Katherine W. Bauer, Ph.D., of the Center for Obesity Research and Education at Temple University in Philadelphia, and colleagues evaluated the change in energy content of lunch and dinner menu offerings at eight of the leading fast-food restaurant chains in the U.S. between 1997 to 1998 and 2009 to 2010.
