Your daily cup of joe might be helping your heart.
Drinking four cups of coffee could help improve your heart according to new research out of Germany. The study was conducted on mice that were pre-diabetic, obese, and old. Research showed that the caffeine, equivalent to four cups of coffee, made a protein called p27 move into the mitochondria of cells.
The p27 protein when present in cells is found to protect "...heart muscle cells from cell death, and triggered the conversion of fibroblasts into cells containing contractile fibers -- all crucial for repair of heart muscle..." While more research needs to be done, the study leads say that these findings may change the way we view the consumption of coffee, especially in older people to help prevent heart-related issues.
