Take a look at ingredients for some varieties of Subway's bread and you'll find a chemical that may seem unfamiliar and hard to pronounce: azodicarbonamide.
To say this word, you would emphasize the syllable "bon" but the attention the chemical has been getting has not been good. Besides bread, the chemical is also found in yoga mats and shoe soles to add elasticity.
Vani Hari, a Charlotte, N.C. food blogger who uses the handle 'Food Babe' first noticed the ingredient and created this post. A petition to remove the ingredient gathered more than 50,000 signatures in less than a day. Now, Subway says the ingredient will be removed from their ingredient list.
CBS 5 News discovered the azodicarbonamide is common in many other fast-food chains. McDonalds uses the ingredient in their Big Mac bun. So does Burger King in their whopper.
"Azodicarbonamide. It's a foreign word to me," said Ben Butler, a miller for Hayden Flour Mills here in Phoenix.
Butler said you really only need four ingredients for a healthy piece of bread.
"You need your flour, your water, your salt and your yeast. You'll actually get better flavor and bread that's actually good for you," he said.
Food safety experts say the best way to make sure you don't consume azodicarbonamide is to simply check the food label.
