America's second largest cereal maker, Minneapolis-based General Mills Inc., recently announced that it is reformulating all of its Big G breakfast cereals to be based on whole grains.Aside from the obvious marketing advantages associated with the change, the move aims to have a positive impact on public health. A corporate press release quoted former FDA Commissioner Dr. David Kessler as saying, “This improvement by General Mills... could signal the most comprehensive improvement in the nation’s food supply since the government began mandatory fortification of grains in the 1940s.”
