Besides carbonated drinks, Pepsi also owns brands such as Xerox potato chips and Yum! Brands. Brands (KFC, Pizza Hut), Budweiser Beer (Harbin Beer has been acquired by Chinese mainland) and Quaker Oatmeal (one of the largest health food producers in the world). PepsiCo's road to diversification has been very successful.
