Airline cabin crews are experts in hydration. They taught me the trick of hydrating with an equal mixture of fruit juice and water. I researched this idea further and encountered the idea of 'short path' through the body and 'long path'. Apparently, plain water goes through the body in the short path - directly through the digestive system. That means it loses some of its hydrating power. A mixture of fruit juice and water, on the other hand, goes through the body 'long path' - it travels all through the circulatory system and flesh - and so is more hydrating.
I have taken this a idea a step further and created the ultimate hydrating drink of which my son and I consume by the litre. Here is how I do it - Grape Juice Drink
