Research shows that caffeine and exercise both have anticancer properties. Combine, they offer powerful protection against skin cancer. In research on animals exposed to UVB radiation, Rutgers University scientists learned the pairing increased the animals' ability to destroy skin cancer cells by up to 4 times. Allan H. Conney, PhD, the director of the laboratory for cancer research at the Ernest Mario School of Pharmacy at Rutgers, suspects that caffeine inhibits ATR-A, a genetic pathway that prevents damaged cells from self-destructing. Both caffeine and exercise also decrease tissue fat, which research shows helps cells deconstruct.
What's the best way to combine the two? Drink a strong cup of coffee an hour before exercise, recommend Monique Ryan, RD, a registered dietitian and author of Sports Nutrition for Endurance Athletes. Caffeine can also increase endurance and delay fatigue, which will help you walk longer and stronger. Just don't forget the sunscreen if you are walking outside!
