Doctors are full of advice: Eat healthy. Exercise. Don’t miss your medications. Don’t get that unnecessary test.
The premise behind this advice is simple: most people have little medical knowledge and doctors, by giving their patients more and better information about their health and available treatments, can help them make better decisions. But health education isn’t just the cornerstone of the patient-doctor relationship, it’s also the backbone of an enormous number of policies designed to improve public health.
