Panera Bread Co. said it is progressing on its commitment to remove artificial additives by publishing a list of artificial colors, flavors, sweeteners and preservatives it has eliminated or intends to remove from its Panera Bread and St. Louis Bread Co. food menus by the end of 2016. Panera reportedly is the first national restaurant company in the U.S. to publicly share a comprehensive list of ingredients that will be removed from or never appear in its menu items.
