Coffee against UVB

A moderate cafeine consumption and physical exercise would prevent the carcinogenic effects of the exposure to the ultraviolet radiations B of sun (UVB). Tests carried out on mice by researchers of Rutgers University show that this combination destroyed the cells whose ADN had been damaged by the UVB.

The study was carried out on mice particularly vulnerable to the rays of the sun. Four groups of rodents were created. The first group drank water containing cafeine (the equivalent of one or two coffee cups for the human). Another group made exercise, and third one combined both. A fourth reference group did not introduce cafeine and did not make a exercise. All the groups were exposed to UVB rays . The results show that the group that did both exercise & cafeine had a definitely higher capacity of destroying damaged cells than the other groups. The complete results are published in the review Proceedings for the National Academy of Sciences (PNAS).
