Water is a very important aspect of good health that is commonly misunderstood. Most of us believe that the quantity of water drunk is what’s important – and I do recommend that you consume at least two liters a day. But you must also be aware of the quality of that water.
I advise people to buy a water filter. Mineral water has been left in plastic bottles for too long (it can sometimes be stored in warehouses for up to two years) so the chemicals (such as PCBs which can cause hormonal disorders) from the packaging may leach into it. Tap water (which has been recycled and filtered many times) has not been tested for certain chemicals that could be very toxic, for example hormones from the contraceptive pill.
Water is also an important element of the fish we eat. Companies, as a by-product of their manufacturing process, are dumping many chemicals into rivers, streams or the sea and these will produce high levels of toxic waste. While farmed organic fish is extremely good for us, we should only eat smaller amounts of the larger marine fish, such as tuna, because of their very high levels of the ‘heavy metals’ mercury and lead. Avoid, too, shellfish such as oysters and mussels: their nickname – the ‘scavengers of the seabed’ – explains why!
It can be incredibly difficult for the body to expel heavy metals, particularly if it has ingested high levels of lead or mercury, for example, over a period of time. Because they have no natural metabolic pathway (the chemical channel that allows them to be broken down and eliminated), these substances end up being stored in the body’s fat cells or organs, where they disrupt organ function which may contribute to infertility or memory loss.
