FILE - This is a Wednesday, Nov. 14, 2007 file photo of Nicaraguan workers carry sacks of freshly harvested coffee beans on a plantation on the slopes of the Poas Volcano, northwest of the capital of San Jose, Costa Rica. The World Health Organization's research arm has downgraded its classification of coffee as a possible carcinogen, declaring there isn't enough proof to show a link to cancer. But the International Agency for Research on Cancer, or IARC, also announced in a report published on Wednesday June 15, 2016 that drinking "very hot" beverages of any kind could potentially raise the cancer risk.
