Study shows photoprotective effect of chocolate that is rich in flavanols:
High flavanol levels found in certain cocoa’s and chocolate helps to protect the skin from UV light
- Eating chocolate rich in flavanols can significantly help to protect the skin from UV light
- 90% of all visible skin ageing is directly related to sun exposure
- CHOCOCRU® Extraordinary Flavanol Cocoa and Cocoa Nibs contains a guaranteed minimum level of cocoa flavanols
Wieze, Belgium, 17 September 2009 – An independent study conducted by the London University of the Arts has revealed that eating chocolate rich in flavanols can significantly help to protect the skin from the harmful effects of ultraviolet radiation.1 The study demonstrated that regular consumption of specially produced chocolate with preserved high cocoa flavanol levels can more than halve the sensitivity of the skin to UV light. These striking results are unprecedented and pave the way for new possibilities in nutritional protection against damage caused by the sun. It is estimated that 90% of all visible skin ageing is directly related to sun exposure.²
The double-blind, randomized, in vivo study involved the daily consumption of 20g doses of chocolate by two random groups of each 15 healthy adult males and females. One group was given a rich flavanol antioxidant dark chocolate, the other was given the same dose of chocolate made according to the same recipe but using conventional production methods. In the rich antioxidant chocolate group, the mean minimum erythema dose – or minimum dose of UV to cause reddening of the skin – more than doubled while no significant increase was observed in the conventional chocolate group. The authors of the study state that the photoprotective effect of rich antioxidant chocolate such as that used in CHOCOCRU® products is most likely to be caused by the anti-inflammatory and antioxidant activity of the cocoa flavanols. These vastly greater concentrations are guaranteed in CHOCOCRU® Extraordinary Flavanol Cocoa and Cocoa Nibs.
“Chronic UV exposure is the main cause of premature skin aging and also plays an important role in cutaneous carcinogenesis. Our study demonstrated, for the first time to our knowledge, that regular consumption of chocolate rich in flavanols confers substantial photoprotection and can thus be effective at protecting human skin from harmful UV effects. Conventional chocolate had no such effect.” – Dr. Stefanie Williams, Dermatologist, Cosmetic Science Group, London University of the Arts and private Dermatology Clinic “European Dermatology London”.³
While eating high flavanol chocolate and cocoa in no way replaces the need for sun screen or other forms of protection, this recent independent study shows that consuming chocolate such as CHOCOCRU® Extraordinary Flavanol Cocoa or CHOCOCRU® Extraordinary Flavanol Cocoa Nibs, which is exceptionally rich in natural powerful, cocoa flavanols, can play an important role in helping to maintain a healthy skin.
Previous studies have linked the regular consumption of cocoa flavanols to a whole host of beneficial effects from maintaining cardiovascular health to improved brain function or anti-ageing in general. However, this latest study is the first to demonstrate a link between cocoa flavanols and natural protection from UV radiation.
Maria Constantinou, director of CHOCOCRU® states:
“Many media reports have created the false impression that all cocoas and dark chocolate products have the same health-enhancing benefits even though many contain low amounts of flavanols. For a guarantee of the flavanol content, consumers are advised to seek out products which display the CHOCOCRU® symbol, and list the measured amount of flavanols on the packaging.
