A lawsuit filed against The Coca-Cola Co. serves as yet another warning for food and beverage companies that they shouldn’t make health claims that aren’t clearly backed up by science, experts say.

The Center for Science in the Public Interest, a consumer advocacy group based in Washington, D.C., sued Coca-Cola and the trade association American Beverage Association on Jan. 4, alleging they downplayed the risks associated with its soda products. The case is being heard in the U.S. district court in Oakland, California.
