Coffee Shown to Reduce Oxidative Stress
Paper-filtered coffee is the most widely consumed form of coffee in the US and Europe. A recent study found that coffee brewed in this fashion may reduce oxidative damage in the body.
The study was conducted by a group of researchers from the University of Vienna, the University of Belgrade and Nestlé. Their findings were published in the September 2010 issue of the journal Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis.
For the study, the researchers recruited 38 participants and randomly assigned them to consume 800ml of coffee (3 cups) or water (placebo) daily for 5 days.
At the end of the study the researchers measured DNA damage based on the levels of “oxidized purines” among the participants. They found that participants given the daily dose of coffee saw a 12.3% reduction in that measurement of oxidative damage. The participants who consumed water only was no change.
This study closely follows recent findings from Purdue University researchers which showed that coffee is one of the biggest sources of antioxidants in the western diet.
Research has also shown a potential link between coffee and reductions in the risk of developing diabetes, prostate cancer, cirrhosis and oral cavities. Over half a dozen different studies have also shown that people who drink coffee regularly are up to 80% less likely to develop Parkinson's disease.
