Already think the benefits of coffee are endless? Well they pretty much are: It can even strengthen your DNA. A small 2014 study published in the European Journal of Nutrition found drinking coffee regularly significantly reduced the oxidative damage in the body’s white blood cells, which can hurt your DNA. Instead, the coffee—dark roast, in this case!—helped keep the DNA strong.
Other studies have tried to pinpoint exactly what in caffeine is helping to halt the onset of these diseases. A 2014 study (14) found that caffeine blocks various tau receptors (a protein that contributes to brain cell degeneration). Another study found that caffeinated coffee increased GCSF (15) - a substance greatly decreased in Alzheimer’s patients - levels in the bloodstream.
