If you’re trying to cut down on your coffee consumption for the sake of health, you may want to reconsider. A new meta-analysis shows that drinking three to four cups daily is linked to various positive health outcomes:
Drinking coffee is more often linked with benefits than harms. For some conditions, the largest benefit appeared to be associated with drinking three to four cups of coffee each day. This included lower risk of death from any causes, or getting heart disease. Drinking coffee beyond these amounts was not associated with harm, but the benefits were less pronounced.
Drinking coffee was also associated with a lower risk of developing type 2 diabetes, metabolic syndrome, gallstones, renal stones and gout. We also found that it was associated with a lower risk of getting some types of cancer, Parkinson’s disease, depression and Alzheimer’s disease. But liver diseases stood out as having the greatest benefit compared with other conditions.
