Sandwich chain Subway says it is removing a controversial chemical from its breads.
The chemical– called azodicarbonamide — is used to strengthen bread dough.
It’s also found in yoga mats and shoe soles to add elasticity.
Subway released a statement saying it’s in the process of removing the chemical as part of its bread improvement efforts.
The chain notes, however, that the ingredient is approved by the USDA and the FDA.
Grocery store breads and other restaurant breads also contain this chemical.
According to the center for science in the public interest, one of the breakdown products derived from the chemical is a recognized carcinogen and poses a small risk to humans.
The ingredient is banned as a dough improver in the european union and in australia.
