Of the 402,260 participants, about 42,000 drank no coffee. About 15,000 drank six cups or more a day. Most people had two or three.And knowing is half the battle!
By 2008, about 52,000 of them had died. Compared to those who drank no coffee, men who had two or three cups a day were 10 percent less likely to die at any age. For women, it was 13 percent.
Even a single cup a day seemed to lower risk a little: 6 percent in men and 5 percent in women. The strongest effect was in women who had four or five cups a day — a 16 percent lower risk of death.
