Nisin most often is found in dairy products, like cheese, but in small amounts, or about 25 to 37.5 mg per kilo. Combatting cancer requires a much greater amount of nisin, about 800 mg/kg. So no, you can't just eat a wedge-load of cheese after a bad diagnosis. But the findings mean there is hope, and it's all thanks to your melty, gooey, dairy favorites.
Additionally, nisin was found to combat antibiotic-resistant bacteria, including MRSA, which otherwise can be deadly. In fact, "To date, nobody had found bacteria from humans or living animals that is resistant to nisin," Dr. Yvonne Kapila, a professor at the University of Michigan School of Dentistry, said.
