In the past I've had a few posts up on this blog which had tried to state that the meme of 8 glasses of water a day had no basis in science - for example the Water Myth!
Then this news release pops up on Eureka:
Cranky today? Even mild dehydration can alter our moods
But of course if you read further you get this interesting bit of information:
The dehydration studies were supported by Danone Research of France
Danone? Oh that's right, Danone sell Evian and Volvic water..... is it any surprise that they want you to drink more of it?!
Get real folks. The modern obsession with water is a marketing trick.
