The big hubbub about Subway using Azodicarbonamide earlier this week, a compound used in making shoes and yoga mats, is just the tip of the iceberg when it comes to this chemical. Turns out that this chemical has been in more laps than a napkin when it comes to fast food chains. McDonalds, Chick-fil-A, Burger King, and Wendy’s are just a few perpetrators, making it appear that Subway may have been unfairly singled out. So if you’ve ever thought your Whopper tasted leathery, well, this may be why. Some products to avoid on your next grocery run may include: Wonderbread, Sara Lee bread and bagels, and Pilsbury Toaster Strudels, as these products also use Azodicarbonamide. Subway has promised to stop using the ingredient in their bread (although a specific deadline would be nice), and Starbucks has said that the products that do use the chemical are being phased out. No word yet on the other corporations, but if people are as outraged as they were about Subway, then it hopefully won’t be long before we have leathery-free fast food. While Subway is busy "phasing out" chemicals from their bread, BodyRock can help. All the recipes in our guides are completely yoga-mat free!
