[Hari] takes innocuous ingredients and makes you afraid of them by pulling them out of context (Michelle Francl, in a review of Hari's book for Slate, expertly demonstrates the shallowness of this gimmick). This is how Hari demonized the harmless yet hard-to-pronounce azodicarbonamide, or as she deemed it, the "yoga mat chemical," which is yes, found in yoga mats and also in bread, specifically Subway sandwich bread, a discovery Hari bombastically trumpeted on her website. However, as the science-minded among us understand, a substance can be used for more than one thing perfectly safely, and it doesn't mean that your bread is made of a yoga mat if it happens to contain azodicarbonamide, which is FDA-approved as a dough-softening agent. It simply means your bread is composed of chemicals, much like everything else you eat.
Hari's rule? "If a third grader can't pronounce it, don't eat it."
My rule? Don't base your diet on the pronunciation skills of an eight-year-old.
