I looked up newsgroups talking about cancer diets and read about
Chinese green tea. A nurse who noted my intake of vitamins and
supplements commented that, yes green tea is drunk in China, and
Chinese have a low rate of bladder cancer, but they also have a
higher rate of stomach cancer. Doctor advised me to avoid tea with
caffeine, drink herbal instead.

Did that doctor imply that caffeine was carcinogenic? That would be
new to me.

Long story short, I drink daily a couple large mugs of Chinese green
tea, removing 80% of the caffeine with a 30 second blanch.

Assuming you really want to remove most of the caffeine, 30 seconds
won't do it. We've been over this territory countless times in this
newsgroup. Please check the archives; I think you'll be persuaded.
