Kellogg this week welcomed a new CEO. Former Anheuser-Busch InBev, Coca-Cola and The Nature's Bounty Co. executive Steve Cahillane took the hot seat at the US cereal and snacks giant on Monday (2 October). The 52-year-old replaces Kellogg veteran John Bryant, who oversaw a challenging period for the business but made progress in some areas. Dean Best reports.
