03 Apr 2020 --- The European Food Safety Authority (EFSA) has rejected the claimed effect put forward by German coffee retailer Tchibo that consuming an Arabica roast coffee blend could reduce DNA damage occurring in white blood cells. This ruling was taken considering the lacking cause and effect relationship between the consumption of Coffee C21 and the protection of DNA from strand breaks. In other jittering research, a study to be presented at the American Chemical Society found that dark-roasted hot-brewed coffee contains more antioxidants from the grind than its counterpart.
