每天真的要喝八杯水吗？

We are awash with positive messages about the healing properties of water and how it will improve everything from our brains to our bowels. And we know that without it we will die in days.

It's a short leap of logic to think that if a lack of water is bad for for you then hydration must be good - purifying, cleansing water washing though your organs must be beneficial, detoxifying. It surely improves your skin, helps you think, reduces your risk of kidney stones and turns your urine a lovely light, straw/champagne colour rather than the fetid orange syrup you produce at the end of a long day where you haven't had time to drink.

So I've looked through the literature and I found a review article saying all of this and more. It was written by a group of respected physicians from American and French hospitals and it clearly supported the widely held belief that you should drink two to three litres of water a day.

It said that people with a high urine output have a lower rate of kidney stone disease, that the flushing action of the water may reduce the risk of a urinary tract infection (especially in women after sex). Perhaps most importantly, they referenced a surprising study which showed that paradoxically an increased intake of water increased the risk of bladder cancer. But only tap water. And there's the clue.

A footnote at the end of the article explained that what you thought was a scientific article in a scientific journal is in fact a supplement, sponsored by a major mineral water manufacturer. All of the authors received honoraria from this company, which also provided medical writing assistance. So this isn't research, it's marketing.
