Dannon will stop claiming that one daily serving of Activia yogurt relieves irregularity and that its DanActive dairy drink helps people avoid catching colds or flu, the Federal Trade Commission announced on Wednesday.
"These types of misleading claims are enough to  give consumers indigestion," says FTC Chairman Jon Leibowitz. "Companies  like Dannon shouldn't exaggerate the strength of scientific support for  their products."
The move signals a more aggressive federal watchdog roll over deceptive  advertising practices by major marketers under the Obama administration
The FTC charged that Dannon's ads were deceptive because it did not have  substantiation for its claims. The commission also charged that  Dannon's claims that Activia and DanActive were clinically proven were  false.
