PepsiCo Inc.'s Frito-Lay unit will begin using corn oil to make Doritos, Tostitos and Cheetos snack foods as more people seek to eliminate harmful fatty acids from their diets.
The switch from soybean oil, which contains higher levels of trans fatty acids, will be made next year.
PepsiCo shares fell 43 cents to $36.77 on the New York Stock Exchange.
