The tea study is stronger than the coffee
study, said Dr. Ralph Sacco, chairman
of the department
of neurology at
the University
of Miami Miller School of Medicine.
The coffee study, though interesting, "still needs confirmation," he said. The research was like a snapshot in time, asking people about coffee habits at a given point.
Better, he said, is to do a study in which participants are followed over time to determine if there is a link between coffee drinking and stroke.
