New research from the University of Arizona found that pizza can fight the norovirus, which is marked by vomiting and diarrhea. Yep, there goes my appetite. Carvacrol, the substance found in oregano oil that gives pizza its distinctive smell, breaks down the tough, protective exterior of the norovirus. Researchers think that possibly this weapon carvacrol could be used as a food sanitizer and maybe a surface sanitizer to combat the mostly food-borne virus. And it’s safe, non-corrosive, and won’t produce any dangerous by-products. And because of how it attacks the virus, it’s unlucky that the norovirus will ever build up a resistance to the substance.
