How Much Coffee is Too Much?

According to the latest U.S. Dietary Guidelines, you shouldn’t consume in excess of 400mg of caffeine every day. In coffee terms, that comes to roughly four cups. If you’re regularly drinking more than that, say the leading health experts from the Mayo Clinic, you’re putting yourself at greater risk of side effects that include headaches, a faster heartbeat, muscle tremors, insomnia, and prolonged nervousness. But if you’re an adult man who is concerned about developing prostate cancer down the road, a new study says that there is at least one major upside of drinking “several cups” of coffee every day that you probably didn’t see coming: Each additional cup of coffee you drink every day is linked to a reduced risk of developing prostate cancer.

For the study, which was published last month in BMJ Open, a team of researchers analyzed 16 different coffee-related studies that were conducted across three continents. All told, they analyzed coffee consumption habits and health markers for more than 1 million men, “of whom 57,732 developed prostate cancer.” Ultimately, they found that “each additional cup” of coffee was associated with a “reduction in risk of nearly 1%.”
