In a recent study, immunologists at Harvard University discovered that people who drank five cups of tea a day for 2 weeks transformed their immune system T cells into "Hulk cells" that pumped out 10 times more cold and flu virus-fighting interferon than did the immune systems of those who didn't drink tea.

Green tea has long been known to protect against certain types of cancer, but the fermentation process involved in making black tea was thought to destroy the protective compounds.
