Coffee is being tied to a decreased risk of dying from heart disease, cancer, and stroke in a pair of studies published Monday.
Yet, some experts are skeptical, suggesting a link isn’t as strong as the new research suggests.
Researchers from the International Agency for Research on Cancer and Imperial College London studied the data from 500,000 healthy people above 35 years of age in ten European countries. Their findings, published in the Annals of Internal Medicine, suggest lifespan may increase by drinking three cups of coffee a day.
On average, an additional daily cup would add three months for men and a month for women. This claim held true for decaffeinated beans too, which suggests the caffeine isn’t the cause.
According to BBC, skeptics highlight the fact that the study ignores the income of the coffee drinkers compare to the non-coffee drinkers. Wealthier people may be more likely to get better health care, which would explain the increased lifespan if they’re also coffee drinkers. Previous studies also conflict with the current studies’ findings.
