Twelve cups of tea a day...

Prompted by my (soon to be ex) office manager, yesterday I kept a tally of how many cups of tea I drank during the course of the day...I don't know if, in a quantum way, by the very act of monitoring my behaviour I altered it in any way (I tried not to, but you never know) but the end result is that, on this occasion at least, I consumed twelve cups (with a spot of milk, no sugar, ta)...

This, slightly surprising figure, caused both he and I to raise our eyebrows a little...but is it actually bad?

From one point of view, no, it's actually quite the contrary - to quote Wikipedia -

"Tea leaves contain more than 700 chemicals, among which the compounds closely related to human health are flavanoides, amino acids, vitamins (C, E and K), caffeine and polysaccharides. Moreover, tea drinking has recently proven to be associated with cell-mediated immune function of the human body. Tea plays an important role in improving beneficial intestinal microflora, as well as providing immunity against intestinal disorders and in protecting cell membranes from oxidative damage. Tea also prevents dental caries due to the presence of fluorine. The role of tea is well established in normalizing blood pressure, lipid depressing activity, prevention of coronary heart diseases and diabetes by reducing the blood-glucose activity. Tea also possesses germicidal and germistatic activities against various gram-positive and gram negative human pathogenic bacteria. Both green and black tea infusions contain a number of antioxidants, mainly catechins that have anti-carcinogenic, anti-mutagenic and anti-tumoric properties".

- however, it does also contain quite a lot of caffeine...50mg per cup in fact...which means I am dosing (although spread out over 9-ish hours) on roughly 600mg of caffeine per day...this *seems* like a lot to me, even though (medically) there is "very little risk of harm" (see the note above the chart) - and (in my defence) - I barely touch a drop of tea outside the office (I go every week night and all weekend long without so much as a sniff, with no ill effects at all)...

But it's given me pause...What do you think? Is twelve cups of tea a day too much?
