Parabens are used as a preservative in many foods, including many tortilla brands, which means they're likely somewhere in your pantry or fridge.
You don't necessary have to throw everything away though. NPR spoke to Dr. Mokoto Mukai, who studies food safety at Cornell University, about the potential dangers of parabens in your food. According to her, the study that provoked so much concern about parabens in food (a 2004 study published in the Journal of Applied Toxicology) lacked a control group, making the results less clear.
She explained the study: "[T]heir suggestion was that deodorant was causing breast tumors."
However, they did not compare the paraben levels in a patient with a breast tumor to a patient without one, which makes the science less clear. "Because they didn't have a patient without a breast tumor, they didn't have a control group. So that [research] doesn't really tell us anything," she explains.
With that in mind, Dr. Mukai does not think that you need to purge your cabinets of every sign of parabens since there is no direct link between parabens and cancer. She explains, "Parabens have been used for more than 50 years ... and they are safe."
However, more research on parabens is necessary to know exactly how they might impact you.
Likewise, if you do want to restrict the amount of preservatives in your food, it is a good idea to check your favorite foods' packaging for any parabens or other preservatives.
