Telling People To Drink Eight Glasses Of Water A Day Is "Debunked Nonsense", Doctor Argues

Yep.

Is it a myth that drinking at least eight glasses of water a day is necessary to prevent dehydration? Dr. Margert McCartney, a GP (general practitioner, primary care physician) says it is more than nonsense "it is debunked nonsense".

There is no available compelling evidence which demonstrates the benefits from drinking lots of water, Dr. McCartney writes in the BMJ (British Medical Journal). However, advocates for the "we don't drink enough water" myth abound - even the National Health Service (NHS) of the UK is an advocate.

On its website, NHS Choices writes:

"Try to drink about six to eight glasses of water (or other fluids) a
day to prevent dehydration."


Several UK schools insist that their kids walk about with a bottle of water.

Dr. McCartney accuses several organizations which have a vested interest in high water consumption of reinforcing this myth.

French food company Danone, which makes and markets Evian and Volvic, tells people to drink from 1.5 to 2 liters of water each day. The company says it is "The simplest and healthiest hydration advice you can give." The company even warns people of the dangers of developing several diseases as a result of mild dehydration.

Literally pissing away money when you buy and drink all that bottled water.

A waste.
