We knew pizza was good for you and now researchers at the University of Arizona have proven that a chemical found naturally in America's favorite food can prevent "winter vomiting disease," which is the leading cause of vomiting and diarrhea illnesses worldwide.

Usnews.com reports a natural chemical in oregano oil – which gives pizza its delicious flavor and smell – could help prevent the spread of norovirus, the culprit in the affliction that made recent headlines after sickening more than 600 passengers aboard a Royal Caribbean cruise ship.

Researchers from the University of Arizona found that the chemical, carvacrol, breaks down a tough outer coat of proteins that shield the norovirus, allowing antimicrobial disinfectants to then go in and kill it. The catch: carvacrol works when used as a sanitizer like Lysol, not when eaten with pizza.
