Special Coffee Roast Found to Increase DNA Protection and Aid Weight Loss
Two recent studies suggest that a special blend of coffee that includes both roast coffee and green coffee may protect DNA from damage and also contribute to greater weight loss.
In the first study, 84 healthy men were instructed to consume either the special coffee blend or water for four weeks. At the conclusion of the study, the researchers noted that the water group had slightly more DNA strand breaks, whereas the coffee group had fewer. The difference between the two groups was 27%.
The second study also included 84 healthy men, but this time they drank either regular coffee or the special blend for four weeks. At the conclusion of the study, the regular coffee group had an average weight loss of 3.3 lbs, while the special coffee group had an average weight loss of 3.75 lbs. Additionally, DNA-protection effects were observed in both groups.
Researchers from the University of Kaiserslautern in Germany conducted both studies. The first study was published online ahead of print on April 17, 2014, in the European Journal of Nutrition. The second study was published online ahead of print on May 24, 2014, in Food Research International.
Previous studies have shown that coffee has a number of health benefits. These benefits are generally attributed to the powerful antioxidants found in coffee called polyphenols and include reducing the risk of developing diabetes, prostate cancer, cirrhosis and oral cavities.
