Flavanol-rich cocoa makes skin moister and smoother, and reduces redness too. Its strong anti-oxidant properties help to maintain the skin's general health as well as to prevent visible signs of aging such as wrinkling.
Researchers tested the effect of
flavanols in beverages. However, they also wrote that the amount of
flavanols in the test drinks "are similar to those found in 100 grams of dark chocolate
."Controlled testing found that the
flavanols increased skin thickness, blood flow, and hydration, and reduced reddening in response to UV rays.
"This study demonstrates that the regular consumption of a beverage rich in
flavanols can confer substantial
photoprotection as well as help maintain skin health by improving skin structure and function," wrote the researchers in the new issue of the
Journal of Nutrition (Vol 136, pp 1565-1569).
Chocolate protects you from sunburn? It seems to be the case. We're not saying you should give up your sunscreen, but it's nice to know that eating delicious chocolate may help reduce the risk of melanoma and other UV-related dangers.
Polyphenols, including the
catechins found in cocoa, can actually absorb UV light. The compounds can also reduce reactive oxygen species (ROS) that are formed during photo-oxidation.
As with all of chocolate's health benefits, these effects come not from sugar but from cocoa -- the chocolate itself. You can't expect to see lovelier skin from grabbing a low-cocoa candy bar out of the vending machine. Stick with real chocolate to see the health benefits.
