18 Oct 2018 --- Panera Bread has become the first national restaurant company to disclose the whole grain content of breads on its menu. On all breads over 50 percent whole grain, Panera now labels servings of whole grain per slice, roll or bagel, as well as the whole grain percentage, so guests know exactly what they are eating. The new labeling commitment also coincides with the launch of “Food Interrupted,” Panera’s first-ever digital platform aimed at providing increased transparency.
