This just in: that “healthy” veggie sub you’ve been ordering at Subway? It’s made with tomatoes, lettuce, bell peppers, and azodicarbonamide. Which, in addition to sounding like a terrifying futuristic weapon, is also a chemical found in products like shoe leather and yoga mats.

Sound delicious? Not really.

Thankfully, this week the fast food chain announced it would no longer use azodicarbonamide in its bread.

The decision was made after food blogger Vani Hari outed Subway’s use of the chemical on her popular website, FoodBabe.com. In a post, she called on readers to sign her petition to get them to stop using azodicarbonamide as a bleaching agent in their bread.

A spokesman for Subway said that fast food spot had already planned on making the change even before the petition began. “The complete conversion to have this product out of the bread will be done soon,” he said in a statement. Subways in places like Australia and Europe do not use azodicarbonamide in their recipes.

Although the chemical is used in other food products around the country, Hari decided to focus her efforts on Subway because of the health-conscious image they try to project. It’s all part of a new (and awesome) trend toward paying closer attention to what Americans put in their bodies.

And we’re pretty happy about it. Munching on a chemical used in yoga mats doesn’t exactly sound like eating fresh.
