Green Tea and Cancer Research.

Some studies have found that green tea could reduce
the risk of many cancers including cancers of the breast, prostate, mouth, foodpipe, stomach and bowel. The most promising studies were done in Asian countries. Studies in Western countries have mostly found no effect on cancer risk.



These differences may be because Asians drink large amounts of the tea while people in Western countries drink mainly black tea.

The tea contains high levels of a group of chemicals called catechins. Because of the way it is prepared, it contains 3-10 times more catechins than black tea. Laboratory studies on cells have shown that catechins could block the growth of cancers. They prevent DNA damage by mopping up free radicals, blocking the growth of tumour cells and stopping the activation of cancer-causing chemicals.

We still need more evidence from large-scale studies and clinical trials to prove that the tea could help to prevent some cancers.
