Narrator: This is Science Today. Americans have dramatically reduced their risk of dying from heart disease by using a little common sense. This according to Doctor Lee Goldman, a researcher at the University of California, San Francisco who found that Americans are living longer simply by smoking less, eating healthier and lowering their cholesterol.
Goldman: Every now and again, what your mother told you to do was right. And our paper really emphasizes the tremendous public health benefit of healthy living and paying attention to some of the most basic of risk factors. It doesn't seem like rocket science, but the benefit to the U.S. population is really very substantial.
Narrator: And Goldman says his research shows that ongoing efforts should have reasonably similar benefits.
Goldman: Our analyses suggest that really simple preventative measures probably explain half or more of the decline in heart disease mortality in the U.S.
