Indra Nooyi CEO and chairman, PepsiCo

As head of a company that earns billions churning out some of the world’s most beloved junk foods, Nooyi has embraced an unusual cause: health. Since assuming the top job at the world’s second-largest food company, she’s made it her mission to make the Pepsi brand and all its products compatible with a healthy lifestyle. That’s meant diversifying as well as tweaking existing products (think low-cal Gatorade, wholesome Quaker Oats, drinkable soups). Her biggest project these days is in the lab, where Pepsi scientists are working to develop lower-sodium salt crystals and a palate-pleasing, nontoxic sugar substitute.
