Tea and coffee protect against kidney cancer

Drinking tea or coffee every day can lower the odds of developing kidney cancer, say scientists.

They believe that the antioxidant content of the beverages may improve insulin sensitivity and lower renal cancer risk.

Scientists from Harvard Medical School in Boston reviewed 13 studies evaluating the relationship between coffee, tea, milk and soft drinks and renal cancer risk.

Participants who drank one cup of tea or three cups of coffee a day had a lower risk of renal cell cancer than others.

Soft and vegetable drinks did not reduce participants' risk of developing cancer.

"Our findings provide strong evidence that neither coffee nor tea consumption increases renal cell cancer risk," say the scientists.

"Instead, greater consumption of coffee and tea may be associated with a lower risk of renal cell cancer."

Zoe Wheeldon at the British Coffee Association said: "Many have proven that coffee consumption is not associated with the development of cancer and it's good to see further evidence that it may in fact have a positive effect.

"This study adds to the wealth of evidence showing that moderate coffee consumption of four to five cups per day is perfectly safe and may confer health benefits."
