Panera is creating a group of food experts that can advise brands on bringing natural ingredients to their menus. Called Clean Consultant, it's in line with Panera's goal of sustainability and using "clean" ingredients. The chain is also petitioning the US Food and Drug Administration to establish a definition of the word "egg." It has been a successful strategy, with Shaich citing a 86-fold increase in shareholder value from July 1997 to when the chain announced plans to go private in July 2017.
