In the study, there were 868 deaths among the participants, some of whom smoked. So, according to study leader Janet Hildebrand, it appeared coffee did not have a protective effect.
Hildebrand, an epidemiologist and population expert with the American Cancer Society, says there was a proportionally higher risk of cancer among those who drank less of the hot beverage, compared to the cancer risk of those who consumed the most coffee each day.
“So it went down a little bit with each cup. And the lowest risk found was with four, five, six cups per day,†Hildebrand said.
Investigators found only a slight health benefit in drinking two decaffeinated cups of coffee, but no advantage was found among tea drinkers, although tea, particularly green tea, is known to have other health benefits.
