You might not want to know what Subway has in common with yoga mats and shoes soles. A chemical used to make these these items has also been found in the bread at Subway.
They are already in the process of removing azodicarbonamide as a part of their bread improvement efforts. The chemical is FDA approved, however, officials said it's been poorly tested.
Azodicarbonamide is used to help strengthen the dough. Health officials said not only is the chemical dangerous, but so are some of its byproducts. One of them is even a recognized carcinogen.
Another one was found to cause lung cancer in mice. Some studies suggest it can even lead to asthma. Subway isn't the only place to use it. Some grocery stores, restaurants and other major fast food chains use this chemical in their bread too.
The chemical's already been banned in Europe and Australia. Many of you said it's scary not knowing what's really in our food.
"I about had a heart attack. Here we are, eating this stuff that we think is healthy for us and we find out the opposite," said Bonnie Celestine, an Upshur County resident.
"I was kind of surprised to hear about it because you think of them as a healthy choice when it comes to fast food," said Rachel Jarvis, a Harrison County resident.
Experts said the level of risk is uncertain. That's why exposure levels should be reduced as much as possible.
