Tea & Cancer 
Researchers from the National Center for Toxicological Research in the United States, demonstrated that the flavins and polyphenols significantly inhibited the growth of human pancreatic and prostrate tumor cells . 

Their research also indicated that tea could have a role to play in changing the genes involved in the process of causing cancer. Another study published in the International Journal of Cancer indicated that men who drink between 2 and 3 cups of tea per day might reduce their risk of developing prostrate cancer by up to 30% compared to the non tea drinkers.

Tea & Cardiac Ailments 
The natural oxidant properties of tea may help reduce the risk of developing heart disease. The polyphenols in tea have beneficial effect on two long established heart disease risk factors - High Cholesterol - High Blood Pressure .

To quote Dr Simon Maxwell, Clinical Pharmacologist, Edinburgh University, " Dietary flavonoids may play in reducing the risk of circulatory diseases".

Tea & Oral Health 
Tea is one of the few natural sources of fluoride and has been shown to have positive effect on preventing tooth decay and gum disease. Scientists believe that drinking tea improves oral health by helping prevent dental caries, by minimizing the possibility of dental plaques, the scale caused by mouth bacteria that leads to gum disease.
