CHICAGO — General Mills, Inc. and The Kellogg Co. have been targeted in a class action lawsuit calling into question the make-up and promotion of fiber in the companies' products. According to the complaint filed Nov. 9 in the U.S. District Court for the Northeastern District of Illinois, Eastern Division, Minneapolis-based General Mills, through its Fiber One brand, and Battle Creek, Mich.-based Kellogg, through its Fiber Plus brand, fail to accurately disclose to consumers on the packaging that the products contain non-natural fiber, which the suit claims "has not been shown by current scientific evidence to possess all of the health benefits of natural fiber."
