Narrator: This is Science Today. Intensive educational campaigns have contributed to lower smoking rates in this country. Ilona Staprans, a researcher at the University of California, San Francisco, says the same type of approach should be taken with the artery-clogging fats found in fast foods.
Staprans: It took years and years and years for people to become convinced that smoking causes heart disease but there are many other factors people are not aware of. We believe that oxidized cholesterol is another very strong factor which eventually will have to be considered in the prevention of heart disease.
Narrator: Staprans says many people may not know how fried and processed foods affect the arteries.
Staprans: It's probably a lack of education. People are just not aware of it, they've heard cholesterol but that's about all. People just don't know how dangerous it might be and what it might do to their health.
