Boxes of Kellogg's cereal are stacked in a supermarket in New York in this April 29, 2008 file photo. Kellogg Co. cut its full-year outlook April 23, 2012 after a disappointing first-quarter performance in Europe and in some product categories in the United States, and its shares fell 5 percent. The world's largest cereal company said it would still invest in future growth. REUTERS/Lucas Jackson/Files (UNITED STATES - Tags: BUSINESS FOOD)
