Drinking limit recommendation "just made up" again, this time it is water.
Today's news services ran an interesting story regarding the recommended dietary intakes for water of 9 - 13 cups as highlighted in the Institute of Medicine's Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate (2004). CBS, NBC, ABC, the BBC, the Guardian, the Telegraph and Daily Mail, among others have all featured articles saying that there is not a single drop of evidence behind the myth of drinking eight glasses or more of water a day.
It turns out that the dietary recommendations from noted medical authorities as well as self-appointed health gurus to drink two or more liters of water per day are totally unsupported by any scientific evidence....
Indeed, it is unclear where this recommendation came from," the University spokesman added....
Because we all have specific individual needs for water, Stanley Goldfarb from the University of Pennsylvania in Philadelphia recommended, "If you're thirsty, drink. If you're not thirsty, you needn't drink."
Having previously shown how the recommended alcohol units were also just made up by the nannies this doesn't surprise me in the slightest.
The Salt Boys obviously note:
This most recent article highlights the specificity of an individual's metabolic need, a situation paralleled by salt intake. The human body has an ability to excrete 250 times the maximum recommended intake of salt - an amount of salt that is virtually impossible for anyone to consume. In other words, our salt consumption is not limited by our ability to excrete it, but rather by our innate senses - sensory perception and biological feedback mechanisms. Both of these mechanisms are specific for every individual, just as water is.
For this reason, it is the very same folly to apply a "one size fits all" set of policy recommendations to salt consumption as it is for water consumption. Salt consumption is self-limiting and regulated by nature's biology, not by shortsighted dietary recommendations.
