This one really perplexes me.
My entire family have never been water drinkers. All through my childhood, I would be lucky to drink a glass of water per week. Instead, we drank 3 cups of tea a day, and lots of weak cordial. Later on I developed a taste for Orange Tang (you'd have to do a Google search I think) and had that each night after school. Otherwise, I lived on Cottees cordial and tea. Zero water
As I grew up and entered into the late 80's and early 90's, the water craze started to take hold. Very large multi-national soft drink manufacturers with huge new interests in water companies, started blitzing the media that 'water was king' for healthy diets and that none of us drank enough of the stuff. Pretty soon, everyone was carrying these water bottles around (a craze that has never stoppped).
I have read the science on all this over the years and of course, and I can see why an intake of water is essential. But, how much more than what your diet already naturally provides from food and other drinks (ie. what your body is telling you to take in, over your belief of what you need) does one actually require?
I've been healthy, fit and muscular all my life - before, during and after water supplementation. Do I REALLY need to drink 4 litres supplementary a day because apparently, none of us drink enough?
