We’ve been hearing for years that coffee, in reasonable doses, is actually good for you.
Now new research, conducted entirely on mice, is looking into exactly why that may be so.
After examining mice with and without a particular cell cycle inhibitor gene, it turns out that coffee actually helps mitochondria in heart cells to transfer more energy, and more energy means fewer heart cells dying.
The gene in question is acted upon by the caffeine found in coffee.
The study mimicked the amount of caffeine contained in four cups of coffee, and found the mice injesting that amount of caffeine had more protected heart muscle cells.
This is also good news for people suffering obesity and type 2 diabetes, which are connected to mitochondrial dysfunction.
The study can be found in PLOS Biology.
