Is tea really good for you?

Yup. Currently there is a lot of scientific research on the health benefits of tea.

Tea is found to be good for you in several ways. The polyphenols in Green tea have been found to increase white blood cells, boosting immunity, and are a powerful anti-oxidant in the prevention of cancer. On the other hand, there is evidence that steeping tea for long periods of time (like all day, ie. sun tea) may actually produce cancer. Green teas also help fight tooth decay and osteoporeosis.

The polyphenols in Oolong and Pu'er can help inhibit cholesterol absorption, and sometimes even lower cholesterol levels. Because of their effect on fats in the bloodstream and grease cutting power, Oolong and Pu'er are known to help also in slimming the fats on the body.

Green and Red teas help maintain healthy blood vessels, preventing blood clots and heart attacks.
