Re:Waterlogged - misguided and misleading

Professor Sanders misses the point. The article examined the claims
that Danone are making, via Hydration for Health. If he wishes to regard
these as "the more whacky claims" about drinking more water, so be it. I
am intrigued that Sanders feels that the British Nutrition Foundation has
an "unbiased view" of the evidence given that this organisation has, as a
'sustaining member' Danone Waters and Dairies Ltd, together with British
Sugar, Coca-Cola and Nestle.
The article was critical of the overselling of drinking more water than we
naturally would without an evidence base to support it.

With regards to Tack and colleagues comments on children drinking
more water, the main purpose of the article was to examine the evidence of
benefit presented by Danone, and was not a systematic review on the
subject. The evidence provided by Danone was, as per the article, mixed at
best. I did not imply or state that it was 'dangerous' for children to
drink 6-8 glasses of water a day: I did imply that Danone's own evidence
did not prove it was useful.
