Food allergies—particularly to common ingredients like eggs, dairy, and peanuts—can significantly alter anyone's life, but even more so for children and those caring for them. A researcher at Michigan State University is trying to pinpoint one of the causes...in your grocery bag.
Cheryl Rockwell, an assistant professor and researcher at MSU, has a son with allergies and started running tests on a common additive that is found in a wide variety of packaged foods. According to Michigan's WILX News, Rockwell points to tert-butylhydroquinone—or tBHQ—as a potential culprit.

According to Rockwell, tBHQ is "used to prevent rancidification or spoilage of food, and it's used in a wide variety of foods." Because the synthetic liquid in which tBHQ is contained is added in small quantities, companies aren't required to include the ingredient on their ingredients label. "There's a limit for a percentage composition of a food for what needs to be on the label and tBHQ is often not included," she says.
