A new study from the Centers for Disease Control and Prevention (CDC) found that fewer schools are carrying soda and junk food on premises, with 44 percent of districts banning junk foods from vending machines last year. The study also saw a drop in school districts that took a cut of soda sales or donations from soda companies. Nancy Brener, lead author of the report and a health scientist at the CDC, notes that though the measures could help, the are not a panacea for the national obesity epidemic. She said,
"There are lots and lots of factors that go into obesity rates."
