In an encouraging development in the coffee-may-be-good-for-us field, researchers have discovered at least part of why coffee appears to be beneficial for the heart.

Coffee consumption or caffeine as an additional dietary factor in the elderly population. Furthermore, enhancing mitochondrial p27 could serve as a potential therapeutic strategy not only in cardiovascular diseases but also in improving healthspan.”
