Last week, Subway announced they will be removing the chemical azodicarbonamide from their bread. The additive is used in a variety of products such as yoga mats, and has been linked to causing asthma and respiratory problems.

Although it is banned in Australia and some European countries, the Food and Drug Administration allows it to be used in the United States. Other fast food restaurants, such as McDonald’s, also use this product.

Subway decided to finally remove the chemical after food blogger Vani Hart petitioned online for Subway to remove azodicarbonamide from its bread. The chemical has not been removed yet, nor has a plan been set in place to improve the quality of Subway’s food.

“I think this just goes to show how little the FDA in the United States is concerned about the foods we eat. If you compare our administration to the administration in other countries, we are way less strict, and it’s disturbing to me that they don’t care what we’re eating,” health teacher Leah Skosky said.

In recent years, Subway has been viewed as a lighter, healthier option as opposed to McDonald’s, especially since the restaurant’s spokesperson Jared Fogle claimed to have lost 245 pounds by eating their turkey-and-veggie sandwiches. The discovery of azodicarbonamide has led people, such as Hart, to question how healthy these chains actually are and whether or not they are preferable to hamburgers and chicken nuggets.

“I think Subway has better options than McDonald’s in general. It’s disturbing that Subway did this because it is seen as a healthier alternative, but apparently it is not very good for you either. In general, I think fast food should be used sparingly. They’re in it to make money, not to make us healthy,” Skosky said.
