Drinking wine or eating grapes could protect you from sunburn, according to a new study that found a chemical in the fruit can limit cell damage.
Ultraviolet (UV) rays emitted by the sun are the leading environmental cause of skin complaints, premature ageing, sun burn and even skin cancer.
The University of Barcelona and the Spanish National Research Council looked at the chemical reaction in the skin when hit by UV rays from the sun. They found that flavonoids in the grapes can stop the chemical reaction that causes cells to die and therefore skin damage.
Marta Cascante, a biochemist at the University of Barcelona and director of the research project, said it proves grapes could help protect the skin from sun burn and even skin cancer.
"This study could help to develop skin creams and other products to protect skin from sun damage, as well as increasing our understanding of the mechanism by which they act", she said.
Already cosmetic companies are registering interest in the hope of making sun creams or pills that copy the process.
The study has been published in the Journal of Agricultural and Food Chemistry.
据英国《每日电讯报》31日报道，最新一项研究发现，葡萄内含有一种化学物质能减少细胞受损，故喝葡萄酒或者吃葡萄都能保护皮肤免受太阳灼伤。
太阳放射出的紫外线是引起皮肤过早老化、皮肤晒伤甚至皮肤癌等问题的主要环境因素。
巴塞罗那大学和西班牙国家研究委员会的研究人员观察了皮肤在太阳紫外线照射下的化学反应，结果发现存在于葡萄中的黄酮类物质可以阻止该化学反应的发生，使皮肤细胞得以存活并免受伤害。
指导该研究项目的巴塞罗纳大学生物化学家玛尔塔•卡斯坎特说，研究表明，葡萄可以防止皮肤晒伤甚至可以预防皮肤癌。
她说：“这项研究有助于研发护肤霜和其他可以保护皮肤免受紫外线伤害的产品。同时，也可以增加人们对这些产品作用原理的认知。”
目前，已有化妆品公司期望能借鉴该方法生产防晒霜或药品。
该研究发表于《农业与食品化学》期刊上。
