Higher consumption of total, caffeinated, and decaffeinated coffee was associated with lower risk of total mortality, and coffee consumption of more than 5 cups/day was not associated with risk of mortality, according to 3 cohorts that included 74,890 women in the Nurses’ Health Study (NHS), 93,054 women in the NHS 2, and 40,557 men. During 4,690,072 person-years follow-up, 19,524 women and 12,432 men died. Researchers also determined:
• Compared to non-drinkers, coffee consumption of 1 to 5 cups/day was associated with lower risk of mortality.
• Significant inverse associations were observed between coffee consumption and deaths due to cardiovascular disease, neurological disease, and suicide.
• No significant association between coffee consumption and total cancer mortality was found.
