Subway, one of the world's biggest bread bakers, is about to remove a chemical from its breads that raised the ire of an influential health activist and food blogger.

The world's biggest sandwich chain says it's in the process of removing the chemical known as Azodiacarbonamide from its sandwich breads

Hard to say right? Well let's just say the chemical in question is used to make Yoga pants and shoe leather more elastic. What the hell? It really is amazing what goes into our food that we have no idea about because they don't have to disclose info like that.

Fresh baked bread -- and the perception of better-for you offerings --is a major deal to Subway. It's one of the chain's central selling points. Just last week, Michelle Obama sat and ate lunch before hosting a press conference at a Subway in Washington D.C. to commend the chain for joining her healthy eating initiative -- pledging nutritious foods on its kids menu.

Food safety and health concerns have become a priority with American consumers who are pressuring the nation's biggest brands to respond. Early last month, General Mills bent to consumer pressure and received positive press after it announced that was removing GMOs from regular Cheerios.

Subway's announcement follows a petition that Hari, the activist, recently launched that asked Subway to stop using Azodiacarbonamide in its bread. The ingredient is banned in the UK, Europe and Australia, notes Hari, who says that she is thrilled with Subway's actions.
