Some Buns Have The Same Ingredient That Makes Yoga Mats
Some breads, particularly fast food buns, contain the chemical azodicarbonamide. The FDA states that the purpose of the substance was to bleach flour and condition dough. The problem is that it’s the same stuff they make yoga mats and rubber shoes from.
When a customer found out that Subway was using the “yoga mat chemical” in their sandwich buns, they petitioned to have the company ban the ingredient. Subway responded by promising to phase out azodicarbonamide.
