Yoga-mat chemical quietly exits fast food

Washington

IN early 2014, a blogger known as Food Babe launched a petition pushing sandwich chain Subway to remove an obscure chemical also used in yoga mats from its bread. Two days and more than 78,000 signatures later, Subway announced it was taking out azodicarbonamide - the yoga-mat chemical, as it came to be known.

Since then, a number of other major fast food chains have followed suit, sans petition or fanfare. McDonald's, Chick-fil-A, Wendy's, White Castle, and Jack in the Box, which all used the chemical in their breads in 2014, have since gotten rid of it entirely.
