    Can it be true? Does Coffee hydrate as well as Water?

     

    UK scientists reckon they've debunked the myth that coffee dehydrates us. They are saying that moderate consumption hydrates the same as water.

     

    A team from the University of Birminghamcompared each, using validated hydraion tests. The study showed that in large doses, (above 500mg a day) caffeine does have a diuretic effect, but as long as we keep 'Old Joe' under control this doesn't kick in.

     

    he results? No significant difference in total body weight, no differences in blood or urine, osmolarity or creatinine.

     

    It's an interesting way to look at coffee vs. water, but frankly, it ignores something far more important; the composition of the water itself. When I was recently in Italy, I drank San pellegrino because of all the waters available, it seemed to refresh and hydrate me best. The label held the answer; sodium! Salt is th single most important factor in our ability to absorb water, along with the hardness of alkalinity of the water.

     

    A separate megastudy of hard water around the world lists literally scores of health problems ameliorated by hard water, while the subject of one study in Czechoslovakia where peope convetrted from local hard water to reverse osmosis 'pure' water revealed that drinking pure water is far less healthy. health complaints in the area skyrocketed.

     

    Alakline water is water that has alkaline minerals dissolved in it, but according to biochemistry specialist Tyler LeBaron of molecularhydrogeninstitute.com, the real secret of high pH water isn't the alkaline minerals but the infused hydrogen. There are now over 210 scientific studies of the health effects of hydrogen, with 60 of these studies foscusing on disease modalities from Alzheimers through to Bipolar disease. In Japan, hydrogen water is available almost everywhere in a range fo forms - bottles, sachets and dispensers.

     

    So for me just comparing hydration abilities of coffee and water is like looking at two glasses of wine and comparing them without tasting them. There is so obviously so much more for us to learn about water.

     

    Hmm. Time for a coffee.This could be the first study of its kind. As such, it challnges a strong urban legend about coffee. Around 1.6 million cups of coffee are consumed daily, so the question of whether it causes low level dehydration has immediate bearing on health at a global level, given that long term dehydration is a powerful ageing factor.

     

    If we look closer, we'll see that there are actually very few studies published over the last decade on the dehydration effects of caffeine. Certainly too few to support the widespread belief in coffee's dehydrative ability.
    The study measured 50 healthy young male coffee drinkers - all non-smokers - habitually drinking 3-6 cups a day. The study was obviously underfunded becasue they were forced to consume 4 Nescafes per day, with 4mg/kg caffeine. No Arabica here!

     

    physical activity, food and fluid intake was also controlled, and total body water was calculated before and after the trial, while urine and blood measures were checked daily, plus nude body mass.

     

    The results? No significant difference in total body weight, no differences in blood or urine, osmolarity or creatinine.

     

    Hmm. Time for a coffee.
