An adult human body is made up of almost 70% water, the brain and heart are composed of 73% water, lungs are 83% water, kidneys and muscles are around 79% water, the skin contains 64% water, even the skeleton structure is 31% water, and the trillions of cells are 50% water

H.H. Mitchell, Journal of Biological Chemistry 158


A simple compound that is essential for all life. Its molecular structure is H₂O (two atoms of hydrogen bonded to one of oxygen). Water is the most common substance in the body, accounting for about 99% of all molecules, but a smaller percentage of total body weight. Approximately two-thirds of the body’s water content is contained within cells, and the remaining third is extracellular (found, for example, in blood plasma, lymph, cerebrospinal fluid, and tissue fluid).

Role in the Body 

Water provides the medium in which all metabolic reactions take place (see metabolism), and transports substances around the body. The blood plasma carries water to all body tissues, and excess water from tissues for elimination via the liver, kidneys, lungs, and skin. The passage of water in the tissue fluid into and out of cells takes place by osmosis.

  • Nature’s No1 life essential

    We are all well aware that we cannot survive for long without consuming water, but are we really aware of how much importance good, quality hydration plays in the proper functioning of our body, and in turn allowing it to operate at optimum efficiency? People can survive for around 5 weeks without food, but only around 5 days without water. The British Medical Association Family Medical Encyclopedia states that; ‘water is a simple compound that is essential for all life’. We are surrounded by living organisms that cannot survive without being nourished with an abundant source of hydration, life as we know it is totally dependent on water. Based on this knowledge, would it be wrong for us to assume that it would be wise to consume the best source of this most essential nutrient available?

  • A chronic acidic state

    Most people are aware of the critical body temperature being 98.6° F, but are unaware of how similar in paramount importance it is for the blood pH to be regulated and remain slightly alkaline within a range of pH 7.35 to pH 7.45. As we unknowingly flood our bodies with acid, nature has provided us with an innate ability to buffer any imbalance – the body will be forced to pull minerals such as calcium, magnesium and potassium from our bones, organs and teeth, even if this will ultimately cause damage to these organs, rather than continue with the blood pH outwith its fine parameters. Consuming alkaline ionised water helps the body neutralise any over-acidity, and at the same time preserve and maintain these essential mineral reserves. pH-scale-updated On the pH scale it is very important to note that each number or division represents a tenfold difference from the adjacent number. As you can see tap water is neutral pH 7, any other liquids in the pH 6 division will be ten times more acidic than tap water – then as the scale decreases, a liquid with a pH of 5 would be one hundred times more acidic than water. Most carbonated soft drinks have a pH of around 2.5 – 3, that means even at pH 3, theses carbonated soft drinks are approximately ten thousand times more acidic than tap water. Some thing to consider carefully the next time you consider drinking one of these soft drinks! Excess acid creates a toxic environment for our body, to prevent further damage and as a life preserving mechanism this acidity is then stored in our body fat to protect our vital organs. This then creates an ultimate recipe for long-term excess body weight problems – if we don’t release the acid we can’t reduce the body weight, as the body needs the storage space.

    pH – The pH of body fluids must be close to 7.4 for metabolic reactions to proceed normally (see acid-base balance). If it falls lower than 7.35, the resulting acidity is called acidosis; if it rises above 7.45, the result is alkalosis. British Medical Association:

  • Metabolism

    A collective term for all of the chemical processes that take place in the body. It is divided into catabolism (in which complex substances are broken down into simpler ones) and anabolism (in which complex substances are built up from simpler ones). Usually, catabolism releases energy, while anabolism uses it. These chemical processes are regulated by proteins called enzymes.

  • Straight from the tap

    Is it better to consume tap water or bottled water? As per normal when it comes to health and wellness information, there is always confusion, particularly when the subject matter is food and drink. Let’s think out of the box and look at this logically – fresh is normally best, so why consume bottled water that could be a few months old and may have travelled halfway round the world to reach you? Where was it sourced from? Was it someone else’s tap? (Remember Coca-Cola and their ‘Dasani’ tap water scandal?) That aside, if it’s in a plastic bottle we have to consider the horrifying prospect of Bisphenol A (BPA) and other chemicals generated by the plastic leeching into and contaminating the water. It therefore makes a lot of sense to drink water from your kitchen tap – on that basis let’s look at how you can improve on the quality of the water being piped into your kitchen.
