Two Australian doctors proved that most ulcers come from bacteria, not stress. One of them literally drank the bacteria to prove it. So why did it take decades for medicine to listen?
Daily multivitamins are a $40 billion industry built on the assumption that more nutrients equals better health. But decades of research tell a different story about why Americans became convinced they need pills to stay healthy.
The warning has been passed down through generations of parents and teachers: stop cracking your knuckles or you'll get arthritis. The science has never backed it up — and one unusually dedicated researcher spent six decades running a one-handed experiment to settle the question for good.
