More Praise for Camellia sinensis
Posted by Bill And lo, the healing legend of green tea grows stronger yet more confounding: Adults in Japan who drank more green tea had a lower risk of death from all causes and from heart disease specifically, though not from cancer, a study has found. (Emphasis mine) This apparently impressive result reinforces the idea that tea's polyphenols delay damage from oxidative stress and inflammation. A big caveat is present, however: The researchers, reporting their findings in the Sept. 13 issue of the Journal of the American Medical Association, wrote that the study isn't the last word: still more rigorous trials will be needed to confirm the results. The ideal would be a "randomized controlled trial" in which some participants are assigned at random to drink the tea while others do not, Kuriyama wrote in an email. Without randomization, the study design raises a big question: how much did green tea itself promote health, vs. how much did those inclined to drink green tea live an otherwise healthy lifestyle? Still, this is merely another result out of many, in vitro and in vivo, that implicates green tea as a mild to moderate elixir. Drink up.

Posted by: Bill from INDC at September 14, 2006 03:01 PM I imagine there is a high correlation between green tea consumption and reading pornographic manga. This might explain the longevity ascribed to beverage imbibers. Posted by: Flea at September 14, 2006 05:46 PM The best thing about green tea is the theanine. The Nipponese actually spike their soft drinks with it, which I'm sure is a huge relief to the parents. Posted by: TallDave at September 15, 2006 02:36 PM I'm just gonna go ahead and die early since green tea is like sipping puddle scum. The Japanese drink stuff named Calpis and Pocari Sweat though so puddle scum probably sounds downright appetizing to them.

Posted by: Babs at September 15, 2006 10:22 PM It's important for everyone to understand that increases of 15% (or even 50%) are not worthwhile. The standard for "relative risk" is 2 - which correlates to a 100% increase or decrease before you can even think about saying there's a correlation between what you're measuring and the effect you think you're seeing. In other words, from an epidemiologic standpoint, probably 95% of the headlines of the day are meaningless. Thus the bizarre stories about eggs = BAD, then the next week eggs = good. Ad infinitum. Many (or most?) of the press releases you see are from studies in hot areas where the authors expect to be able to receive further grant money. Nothing says progress like a press release showing some correlation* (*as long as you don't analyze the study too much or ask about the biases). Posted by: Scoob It's important for everyone to understand that increases of 15% (or even 50%) are not worthwhile. Given that presumption, you've indicted the anti-depressant formulary as placebos. (For example) Posted by: Bill from INDC at September 16, 2006 04:16 PM Mind you I'm not saying the results are definitively not correct, only that the studies are quoting less than epidemiologically significant results. It may be that they just haven't identified (and corrected) biases and confounding factors, but they're headed in the right direction. Unfortunately in this "publish it immediately" atmosphere, it's hard to say who is doing legit research and who is fishing for more grant $$$. Posted by: Scoob at September 16, 2006 09:13 PM And it's not a presumption. Epidemiologic standards are written into the author guidelines of most (if not all) medical journals. Check out this link for an article written by Gary Taube about 10 years ago in Science: http://www.nasw.org/awards/1996/96Taubesarticle.htm Posted by: Scoob at September 16, 2006 09:30 PM That's a good link. Yeah, you're right, as my counter-example was thinking in terms of drug studies intended to treat a specific illness, not large epidemiologic studies trying to find associations. Posted by: Bill from INDC at September 16, 2006 09:52 PM if they also 'partoke' of the marijuana then cancer would not be a problem, at least 4 kinds would be eliminated. so that makes it: also legalizing marijuana would resolve all the debt in the country. logic: no more billions to the drug war. almost half the prisons would be empty. we would start recieving taxes from the sales. and caramella sensimellia is so very sweet, like eating cotton candy.
