This is a good article about something I have read several times. It is stated pretty well with a good graphic. It deals with green and black tea with green tea helping slightly more than black tea though if you really like black tea and dislike green tea continue with black tea. I already really enjoy green tea and drink almost daily so I will continue. I believe part of the reason some people do not like green tea is that they use bagged tea, use boiling water and leave the bag tea until done drinking. A good quality loose leaf green tea with the correct temperature of water and not oversteeped can taste great.
