More tasty news for those who regularly reap the mounting health benefits of drinking wine. Partaking of the aromatic and flavorful fermented fruit juice may provide protection against skin damaging effects of ultraviolet (UV) radiation. Researchers from the University of Barcelona and the Spanish National Research Council have discovered that a chemical in the fruit can limit cell damage. Details of the study can be found in the Journal of Agricultural and Food Chemistry.
UV rays emitted by the sun are the main culprits for skin damage, premature aging, sunburn and skin cancer. Previous research has shown that consuming wine can aid in the prevention of Alzheimer’s disease, prostate cancer, and even protect your pearly whites by helping to prevent cavities. The lastest findings only add to the growing number of reasons to let the wine flow and drink up.
The study authors pointed out that although several previous studies have shown that human skin can be protected against UV radiation by using plant-derived antioxidants, theirs is the first study to analyze the effects of wine consumption on human skin. The researchers examined a chemical reaction in the skin when hit by UV rays from the sun to arrive at their conclusions.
The study findings showed that both grapes and grape derivatives contain a compound known as a flavonoid that helps helps to protect human skin from the damaging effects of UV radiation. According to lead researcher Maria Cascante, “This study supports the idea of using these products to protect the skin from cell damage and death caused by solar radiation, as well as increasing our understanding of the mechanism by which they act.”
The researchers explained that reactive oxygen species (ROS) are activiated as UV rays hit human skin. The ROS oxidize lipids, DNA and other large molecules, which leads to the activation of other enzymes that kill skin cells. However, ROS formation is deterred in skins cells exposed to UV rays by the flavonoids contained in grapes.
The study findings may pave the way for devloping new methods of protecting skin from harmful UV rays.
Now, I’ll toast to that! So here’s to you, wine lovers. You can have your summer fun in the sun while sipping some tasty UV protection. And for those of you who are not inclined to imbibe, the study evidence suggests that you can still reap the benefits by eating grapes.
