Well here in Ireland we drink tea at breakfast, after lunch and after tea and of course to cure a hangover and to settle the nerves! Tea is full of antioxidants even though it contains caffeine. Everything in moderation!
I also heard something similar you what J. Kumm has stated. Basically some of us including myself like a very hot cup of tea, and too much of this can cause the lining of the oesphagus tract to become inflamed and eventually lead to cancer. I do not know if this is scientifically proven I just read about it the other day.
This is how my family and I prepare tea- I'm fierce fussy with my cuppa.
Boil the kettle. Place a little hot water into a teapot and into a nice china mug (I prefer a china mug as it keeps the tea warm for longer) to warm. Once the teapot has warmed empty the water add approx. 2 teabags into the pot and fill with hot water, cover with lid and leave to wet for 3 minutes. Now take your nicely heated cup and pour some of your freshly brewed tea. Add a little milk and sugar if you want.
Tea is best enjoyed with cakes and good friends.
