    Drinking wine may protect against the harmful effects of sunburn, researchers
    from the University of Barcelon revealed in the Journal of Agricultural and
    Food Chemistry
    . They explained that grapes and grape derivatives have a
    compound - a flavonoid - that helps protect human skin from the damaging effects
    of ultraviolet radiation.

    The authors explained that wine has been shown
    in previous studies to have some effect in protecting against Alzheimer's disease, cavities, and prostate cancer. However, no prior study had
    looked at the effect it may have on human skin.

    The researchers
    wrote:
    "Several studies have demonstrated that human skin can be
    protected against UV radiation by using plant-derived
    antioxidants."



    The scientists explained
    that when UV rays hit human skin they activate ROS (reactive oxygen species),
    which oxidize lipids, DNA and other large molecules, which in turn activate
    other enzymes that destroy skin cells. Flavonoids, found in grapes undermine the
    formation of the ROS in skin cells that are exposed to UVB and UVA
    rays.

    Apart from revealing another benefit from consuming wine, lead
    researchers, Marta Cascante believes that their findings may lead to new ways of
    protecting skin for harmful sun rays.

    The authors wrote:
    "These encouraging in vitro results support further research and
    should be taken into consideration into the clinical pharmacology of
    plant-derived polyphenolic extracts as novel agents for skin
    photoprotection."
