ALAJUELA, COSTA RICA - MARCH 25: Roasted coffee beans are seen on display at the Doka Estate coffee farm on March 25, 2015 in Alajuela, Costa Rica. The farm is one of many that produce high quality coffee that is exported to the United States where a panel of government-appointed scientists at the Dietary Guidelines Advisory Committee charged with proposing changes to U.S. dietary guidelines announced recently that three to five cups of coffee daily do not have long-term health risks, and help reduce the risk for heart disease and type 2 diabetes.
