SAN FRANCISCO, CA - JUNE 10:  Bottles of soda are displayed in a cooler at a convenience store on June 10, 2015 in San Francisco, California. The San Francisco board of supervisors has approved an ordinance that would require warning labels to be placed on advertisements for soda and sugary drinks to alert consumers of the risk of obesity, diabetes and tooth decay. The ordinance would also ban advertising of sugary drinks on city-owned property. If San Francisco mayor Ed Lee approves the  measure, the law would be the first of its kind in the nation.
