Drinking more coffee maybe good for your heart

Awesome news coffee lovers! Another study shows drinking coffee protects the heart with the help of mitochondria.

Caffeine consumption is already associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying these protective effects has been unclear. But this new study now shows that caffeine concentration equivalent to four cups of coffee promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage.

The study was published in PLOS Biology, by researchers Judith Haendeler and Joachim Altschmied of the Medical Faculty, Heinrich-Heine-University and the IUF-Leibniz Research Institute for Environmental Medicine in Duesseldorf, Germany. They found that the protective effect was reached at a concentration equivalent to consumption of four cups of coffee, suggesting the effect may be physiologically relevant, (i.e. levels reached after four or more cups of coffee)

The researchers have previously shown that caffeine improved the functional capacity of endothelial cells, which line the interior of blood vessels, and the effect involved mitochondria, the cell’s energy powerhouses.

“Our results indicate a new mode of action for caffeine,” said Haendeler, “one that promotes protection and repair of heart muscle through the action of mitochondrial. These results should lead to better strategies for protecting heart muscle from damage, including consideration of coffee consumption or caffeine as an additional dietary factor in the elderly population. Furthermore, enhancing mitochondrial could serve as a potential therapeutic strategy not only in cardiovascular diseases but also in improving health span,” she went on to say.

So drink up!
