Happy Monday!
Coffee lovers, rejoice! ☕ Medical science is increasingly finding that all those cups of joe are actually good for us.
Researchers at Mass General Brigham, Harvard, and the Broad Institute had been following 131,821 American doctors and nurses for 43 years (possibly the longest single piece of evidence we will ever get on a daily dietary habit and a chronic disease), and by the end of the study, 11,033 had developed dementia.
But the participants who drank two to three cups of caffeinated coffee a day were 18 percent less likely to be among them. A separate Cleveland Clinic analysis tied the effect specifically to caffeinated coffee. Nature described the relationship in coffee drinkers as “slower brain aging.”
That study didn’t appear out of nowhere. It joins a five-year run in which essentially every major endpoint in coffee research has come back in favor of the bean.
