The International Agency for Research on Cancer says it doesn't know if coffee causes cancer, which is a switch from 1991 when the agency, an arm of the World Health Organization, said it did. That's bad news for those who want to trust IARC's recommendations, because its reasons to reverse course on coffee are no more valid than its reason to have declared it possibly carcinogenic to humans in the first place.
