UPDATE: A previous version of this story highlighted Nature's Own 100% Whole Wheat Bread as a food that contains azodicarbonamide
We have been eating fast food sandwiches made with azodicarbonamide for years. If you don't eat that stuff very often, I doubt you have anything to worry about. And if you do eat a lot of fast food sandwiches, I'd venture to say that azodicarbonamide is probably the least of your concerns.
Subway says it's in the process of removing a chemical from its bread as part of an ongoing effort to improve its recipes.
