Nestle CEO steers food giant to 'gut feeling'

Switzerland's Nestle, the world's largest food company, wants to tune up your guts.

Last weekend, it hosted global experts in Playa del Carmen, Mexico for a three-day workshop on the intestinal microbiome to discuss how trillions of bacteria living in the digestive system can impact everything from obesity to depression.

One attendee was Emeran Mayer, a gastroenterologist at the University of California, Los Angeles, whose family ran a German confectionery business, giving him a unique perspective on Nestle's ambitions.
