Caffeine Can Fight Skin Cancer
There are many debates concerning the benefits of coffee. But it seems that the latest facts about coffee will make coffee lovers smile. Because coffee has been proven able to protect you from skin cancer.
A recent study which tried to complement previous studies that showed that caffeine can be an effective weapon in fighting skin cancer. The study made rats for experiment which was divided into two groups.
The first group of rats had experienced gene modification to deter a particular protein called ATR, and rich in ultraviolet radiation (UV). Meanwhile, the second group of rats were not.
The researchers found that both groups of mice remained free of tumors after exposure to UV light for some time. However, after 19 weeks of exposure to UV light, the first group of rats experienced 70 percent fewer tumors compared to the second group of mice.
This research helps explain how caffeine can reduce the risk of exposure to sunlight that can cause skin cancer. Caffeine can inhibit ATR kinase pathway, which plays a major role in responding to DNA damage. If absorbed by the body, the ATR can inhibit cell division and allow repair of DNA rather than letting the damaged cells die.
“It may sound good, but not all repairs are successful and a few cells are capable of developing cancer,” said Allan Conney, director of the Susan Lehman Cullman Laboratory for Cancer Research at Universitad Rutgers, according to YouBeauty.
This study, which was published in the Proceedings of the National Academy of Sciences, identified that the ATR kinase pathway could be inhibited by caffeine so that damaged cells will die. Ultimately, the emergence of cancer cells can be prevented. However, caffeine does not only impede this important protein. Caffeine also acts as a natural sunscreen.
You also can get sun protection benefits from daily coffee consumption. A 2007 study on nearly 94 thousand women who drank coffee every day, found that skin cancer risk of these coffee drinkers were 11 percent lower than those who did not consume coffee. Meanwhile, women who drank six cups or more a day reduced their risk by 30 percent.
Although you often drink coffee, you should never forget the sunscreen. “The same general rule applies to you to always apply sunscreen with at least SPF 30. And find sunscreen that can protect your skin from UVA and UVB rays. Repeat every two hours even though the day is cloudy, after swimming, or being sweaty,” said dr. Howard Sobel, a dermatologist from Manhattan.
