When you talk about healthier food options, Subway usually gets high marks.

However, the sandwich chain ran into trouble over a chemical it's been using in the bread it bakes at stores around the country. Now, Subway says that chemical will be removed from the recipe. 

The chemical is known as Azodiacarbonamide. A blogger than runs a site called FoodBabe.com says it's used as a bread conditioner, but she says it's also used to increase elasticity in items like yoga mats and shoe rubber. She says the chemical is banned in Europe and Australia.

"We are already in the process of removing Azodiacarbonamide as part of our bread improvement efforts despite the fact that it is USDA and FDA approved ingredient," the Subway said in a statement released to USA Today. "The complete conversion to have this product out of the bread will be done soon."

It's another example of how food activists have pressured major corporations to remove chemical ingredients from its foods. Kraft announced last year it would start using spices to color some of its popular macaroni and cheese products, instead of artificial food dyes.
