(Newser) – Good news for caffeine addicts: Green tea and coffee both apparently help reduce the risk of suffering a stroke, reports NPR. A new study of more than 82,000 adults in Japan found that for coffee drinkers, just one cup a day lowers the chances of a stroke 20%. And for green tea, more is better, with four cups a day lowering the risk by 20%. Five or more cups of green tea a day was found to reduce death from cardiovascular disease by 26% and overall mortality by 15%, notes the Atlantic.

Green tea contains compounds that help regulate blood pressure, improve blood flow, and have an anti-inflammatory effect; coffee is thought to also contain different helpful compounds. Back in the 1980s, doctors often advised against caffeine altogether. But it turns out those studies did not check for one very important variable—smoking. Back then, coffee drinkers were also heavy smokers. "So it made coffee look bad in terms of health outcomes," explains one researcher.

the problem with this is that like everything else they`ll change their minds in a few months ! truth is they have no idea whats good and what is`nt , all guess work ! there was an article recently in one of the science journals that stated that while they are fairly sure that vitamins and anti oxidants are good for us they really cant say why ! inspires all kinds of confidence !

Unfortunately, coffee and tea are super acidic and suck the calcium right out of our bones and muscles to neutralize the acid which will cause arthritis and heart arrhythmia's. I'm sure Japan didn't test their research patients for extenuating variables such as arthritis or heart irregularities.

"So it made coffee look bad" Blasphemy! Java and smokes are a match made in heaven!
