There have been plenty of studies showing the health affects of coffee, but did you know that dark roasts in particular are good for you? If you're a fan of dark roasted coffee, our specialty, then here's another reason to keep your daily habit.
A recent study published in the European Journal of Nutrition showed that drinking dark roasted coffee protects your DNA from breaking.
DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code. Like a recipe book it holds the instructions for making all the proteins in our bodies. DNA constantly incurs damage from agents generated within the cell as well as chemicals or radiation that happen externally. Of the many different classes of damage, a DNA double-strand break (DSB) is arguably the most significant since, if unrepaired it can result in cell death.
The study took a group of people and had them drink water for a month, while the other group drank dark roasted coffee. On the last day of each period, their blood was tested to assess the level of DNA damage (strand breakage). The researchers found that the group who was allowed to drink coffee had fewer DNA strand breaks compared to the control group. That's right. Coffee is better than water. Just kidding, please keep drinking water.
This research isn't new. There have been many studies showing the positive affects of coffee, and in particular dark roasted coffee. For instance, there was a study in 2016 documenting health benefits, and another study in 2015, also published in the European Journal of Nutrition, that found that people who drink three cups of dark-roast coffee had 27% fewer DNA strand breaks in their white blood cells than water drinkers after only a month.
So celebrate your habit! Own it and keep drinking dark roasts!
