Toxic Metals in our environment are the higher today than ever in our recorded history. Essentially everyone today has excessive levels of toxic minerals in their bodies.
What do they do?
Toxic metals are the major cause of inflammation, infection, irritation and tissue damage.
How do they do this?
The toxic metals replace the good nutrient minerals in the enzyme binding sites. When this happens it changes the actions of the enzyme involved. The enzyme may have it's actions inhibited or it may be overstimulate. In any case, the enzyme activity is changed or altered. This does not happen with just one enzyme but with trillions of enzymes.
Toxic minerals will replace other minerals in tissue structures. This could be the arteries, joints, bones or muscles. The result is a slow destruction of these tissues.
* for example if one has high bio-unavailable calcium then lead will replace the calcium, which is a good thing because it prevents a total breakdown of our bones, however, the bone is a less intact bone structure which over time will lead to osteoporosis.
The toxic minerals can cause irritation, necrosis, inflammation, atrophy and other toxic effects.
The toxic minerals support the development of fungal, bacterial and viral infections that are difficult or impossible to eradicate until the toxic metal is eliminated.
They also "short circuit" and otherwise damage the brain and nervous system in many ways, leading to most mental and neurological disorders.
Due to the depletion of minerals in our soil we are consuming less minerals from our food. If our body does not have the minerals it needs (the preferred mineral) then it will take the less preferred mineral in its place.
* a great analogy that Dr. Wilson uses to explain this, which really helped me to understand the concept, is comparing our body to a car. If the fan belt breaks in our engine then what we can do is use a nylon or rope in place of the broken fan belt. This allows us to continue driving the car but it is not going to be operating in its optimal condition. We will just hobble along to the nearest service station. So, the toxic minerals such as lead that replaces calcium in our bones, if bio-available calcium is not available, will keep our bones from falling apart but the bones will not be in their optimal condition and eventually osteoarthritis will set in. So, in this sense the toxic minerals are great because at least we can hobble along and not "fall apart" for awhile.
