a paper which did exhaustive tests on golden hamsters,seemed also to
indicate that caffiene made more potent more standard carcinogens.

that states there there is inadequate evidence for the carcinogenicity

animals.

Hold on a minute, guys.
Caffeine in moderation has been shown to inhibit cancer particularly
in the colon and there are now-being-conducted studies questioning the
duration and efficacy of ionizing radiation in some cases.
The antioxidant qualities in green tea (where been over this so many
times (see archives, this group) are unquestionable, at this point and
justified in many, many studies.
Stomach cancer is high in many Asian countries. Japan has a very, very
high rate. In my opinion due to a sky high consumption of sodium (and
possibly, high consumptions of raw fish and the heavy metals therein).
I would think nicotine, ethanol and all that salt would dis-ease
anything in Japan with or without tea.
To be honest, we don't really know about cancer in China because so
much of the medical data is unsubstantiated.
I would assume levels of gastrointestinal disease is climbing, in
general, due to high levels of pesticides, herbicides and additives in
foods and, of course, high levels of saturated fats and sodium.
Tea in sensible amounts is hardly a culprit.
