15/01/2015 (Bloomberg) - PepsiCo Inc. dismissed as a "stunt" a social-media video posted by environmental activists challenging the snack maker's reliance on palm oil in Doritos. The clip, which was released by SumofUs.org as a spoof of a Doritos commercial, alleges that PepsiCo's palm-oil use destroys rain forests and kills animals. After the ad gained a following online, PepsiCo shot back yesterday, saying its policy on the ingredient is sound and the video distorts the truth.
