Bars of Cailler branded 'branche' chocolate sit on the production line at the Nestle SA production facility in Broc, Switzerland, on Monday, Dec. 19, 2016. Nestle says it found a way to reduce the amount of sugar in chocolate by as much as 40 percent, a discovery that may give the KitKat maker an edge as food producers face increasing pressure from governments, health advocates and shoppers to make products healthier.
