Caffeine and exercise may work together to ward off skin cancer, research suggests. An early study found the combination reduced the number of skin tumours in cancer-prone mice by 62 per cent. Tumours also shrank by 85 per cent in treated animals. Study leader Dr Yao-Ping Lu, from Rutgers Ernest Mario School of Pharmacy in New Jersey, US, said: ‘We found that this combination treatment can decrease sunlight-caused skin cancer formation in a mouse model. ‘I believe we may extrapolate these findings to humans and anticipate that we would benefit from these combination treatments as well.’
Mice exercised on a running wheel after being given a dose of caffeine. Both caffeine and exercise alone produced positive effects, but the benefit was greater when the two were combined. Mice treated with caffeine alone had 27% fewer tumours than untreated mice and their cancers were 61% smaller. In exercise-only mice, tumour activity decreased by 35% and tumour volume by 70%. Caffeine and exercise also led to a weight reduction of 63% in mice fed a high fat diet. Click here to read the article in full.
