Four cups of coffee a day might actually be good for your heart

DON’T REJOICE JUST YET, THOUGH.

Four or five shots of espresso is apparently the perfect recipe for a healthy heart, specifically for older adults, according to a new German study. The results of the study, published in the journal PLOS Biology, claims that caffeine — working as a stimulant — can improve the health and protect the powerhouses of the cells in our blood vessels. There’s a mounting body of evidence to suggest coffee is good for health — people who drink the brown brew seem less likely to die of heart disease, stroke and diabetes, and regular coffee drinkers are less likely to die from any cause as compared to those who don’t drink java. Coffee has also been linked to better liver health, believed to lower the risk of cancer and dementia, and reduced depression. The one caveat: this study was done on lab rats and human tissue, so take this news with a pinch of salt.
