Science Says Your Coffee Addiction Is Good For You

There is probably no other time in your entire life where you drink nearly as much coffee as you do when you are the parent of little kids. Sleepless nights? Coffee. Early mornings? Coffee. Toddler wants to skip their afternoon nap? Coffee. Staying up late just to get a teeny, tiny bit of alone time? Coffee. You could call it an addiction and you would probably be right. Parents of the world can finally rejoice though, because this coffee addiction just might be good for us, according to science.

According to a new study, published by PLOS Biology, our beloved coffee is actually good for our heart and improves respiration-dependent processes in the cardiovascular system. Score! And in even better news? It doesn't matter how many hundreds of times that we had to reheat it in order to get those cups of coffee in our body, just as long as we do.

In all seriousness though, how many times have we sat down and poured ourselves yet another cup of coffee and felt kinda guilty - like we were doing something harmful for our body? The thought has definitely crossed our minds a few times, but as busy parents, we just keep pouring. But, this study reveals that by drinking four cups of coffee per day (which we know is totally doable for every parent) has pretty amazing hearty healthy benefits and the amount of caffeine you get from four cups of joe is the ideal amount for heart health.

The breakdown seems pretty simple. According to the researchers, the amount of caffeine in four cups of coffee pushes an enzyme that typically slows cell division into the mitochondria of your cells, which then triggers your body to start repairing your heart muscles. This is especially great news for anyone who’s had a heart attack or suffers from cardiovascular problems.

Study author, Judith Haendeler of Heinrich-Heine-University and the IUF-Leibniz Research Institute for Environmental Medicine in Duesseldorf, Germany said that "our results indicate a new mode of action for caffeine, one that promotes protection and repair of heart muscle through the action of mitochondrial p27. 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.”

To be fair though, this study has so far only been tested on mice, so further research needs to be done to really gauge the impact that it has on human beings. But with the study's sole focus being on the caffeine and not so much the coffee itself, it means that you can gain the same results with any brand that you love.
