In previous newsletters we have talked about the fact that most of us do not drink enough water. A good rule of thumb that works well for most people is to base your daily water consumption off this chart:
If you weigh 100lbs...drink 50 fluid ounces of water per day
If you weigh 150lbs...drink 75 fluid ounces of water per day
If you weigh 200lbs...drink 100 fluid ounces of water per day
For those of you who do not live in the US the rule can also be stated like this:
Drink 1/3 of a litre of water for every 10kg of body weight. So if you weigh 50kg you need at least 1.7 litres per day. If you weigh 70kg you need at least 2.3 litres of water per day. If you need help with the maths let us know.
So what's the "best" water to drink? Tap water is usually not a good idea as it contains many chemical and biological residues. Admittedly these are present in VERY small quantities but over the course of a lifetime some of these impurities (like heavy metals) can accumulate in quantities sufficient to negatively impact your health.
Ideally you want a water that has plenty of minerals in it but nothing else. Minerals include things like calcium, magnesium, sodium and potassium although your body needs dozens of others to function properly. If you filter your tap water using reverse osmosis, de ionisation or distillation you will end up with a water that has very low concentrations of minerals. EVERYBODY becomes mineral depleted as they age so the smart thing to do is to add some minerals to your filtered water by putting a pinch of sea salt in every glass you drink.
One other point worth noting is that if you are stiff/inflexible it might be a good idea to add extra magnesium to your drinking water. An easy way to do this is to buy Ionic Magnesium made by Trace Mineral Research. Magnesium helps promote muscle relaxation and calcium helps promote muscle contraction. If you have been taking calcium supplements with no additional magnesium this might explain why you feel as if somebody has poured concrete into your body!
