ER did more than make George Clooney a superstar. It also changed the way America ate. In three 2004 episodes, the show explored a minor plot arc about a teenager who learns he has high blood pressure. The show’s physician characters advise the young man to exercise and eat more fruits and vegetables.
While the plot sounds humdrum, it scared viewers straight. In 2007, researchers from the University of Southern California’s medical school published a paper in the Journal of Health Communication that found that viewers who caught these episodes of ER had started walking or exercising more, eating more fruits and vegetables, or getting their blood pressure checked. How can anyone say watching TV is bad for you?
