A. More Bad News For Fast Food

Narrator: This is Science Today. Fast food may offer quick convenience and low cost, but it may also dramatically speed up clogging of the arteries. Ilona Staprans, a researcher at the University of California, San Francisco says animals fed the oxidized cholesterol found in fast foods had double the amount of clogged arteries.

Staprans: We can physically show the difference in arterial fat deposition that oxidized cholesterol or oxidized polyunsaturated fatty acids accelerate the process of fat deposition.

Narrator: Although this has yet to be tested in humans, Staprans says their findings are suggestive since heart disease is still the number one killer and fast food industries are booming.

Staprans: You can't completely avoid fried foods and fried meats and fried eggs - people like hamburgers! People like greasy food! But one could be aware of the dangers and reduce it as much as possible.
