NEW YORK (AP) — Activist investor Nelson Peltz is ramping up the pressure on PepsiCo, reaffirming his call for the company to separate its global drinks division from its snack unit.

The call for a split comes as PepsiCo’s drinks, which include Mountain Dew, Tropicana and Aquafina, have lost ground to bigger rival Coca-Cola Co. in recent years. U.S. soda consumption in general has also been on the decline, with people worried about the calories in regular soda and the artificial sweeteners in diet sodas.
