A natural antioxidant found in good cholesterol holds significant cardiovascular benefits, according to researchers at the University of Minnesota. The enzyme glutathione peroxidase (GPx3) is known to protect organisms from oxidant injury and help the body protect itself. It is also known that low levels of GPX4 can lead to cell death. Now a study claims that patients with low levels of good cholesterol, in which GPx3 is found, could be protected from cardiovascular disease. According to researchers, the enzyme may also indicate those patients at cardiovascular risk. Dr Jordan L Holtzman, lead author, commented: "In our study, we found that people with high levels of the GPx3 enzyme and low levels of good cholesterol were six times less likely to develop cardiovascular disease than people with low levels of both." The findings suggest that more natural antioxidants have cardiovascular benefits, but more research is needed. This will in turn promote lower heart attack and stroke risk.
