Minerals: Selenium And Health
In recent years, the value of the trace mineral
selenium to overall health and well being has come to light. Numerous important
health benefits have come to be associated with maintaining sufficient levels
of selenium in the body, and recent research indicates that this mineral can
play an important role in protecting the body from serious disease and illness.
Selenium is especially important in the body's
ongoing battle against free radical damage. In the body, selenium is the source
of selenoproteins, which are essential anti-oxidant enzymes and are important
to protecting the cells from the damage that unchecked free radicals can do.
Some research has associated free radicals with certain types of heart disease
and cancers.
In addition to their important role in the control
of free radical damage, selenoproteins also serve to strengthen the body's natural
immune system and also helps to produce anti-bodies. Selenium has also been
found be involved in helping to keep the thyroid functioning at peak levels.
The thyroid is responsible for many aspects of health, including the body's
metabolism. Some studies indicate that selenium can be useful in the treatment
of acne and still other research indicates that it may be useful in repairing
chromosome damage. It is thought to counteract heavy metals and other contaminants
that find their way into the body, as well as to help in the prevention of unwanted
and dangerous blood clots.
Deficiency in selenium can have a variety of
significant health consequences. Indeed, researchers have found three debilitating
diseases that are directly related to serious selenium deficiency. These include
Myxedematous Endemic Cretinism, which leaves the victim severely and irreversibly
mentally retarded, Keshan Disease, which leaves selenium deficient children
with an enlarged heart that often does not function properly, and Kashin-Beck
Disease, which causes osteoarthropathy.
The amount of selenium provided by plant sources
depends a good deal on the quality of the soil the plants were grown in. Thus,
poor soil will yield plants that may not provide the expected levels of this
important mineral. That means that those who follow a vegetarian diet, particularly
a vegan diet, which uses no animal products whatsoever, must be especially vigilant
in making sure that they consume enough selenium in their daily diets. A dietary
supplement that contains selenium is a safe and sure means of seeing to it that
the diet is not lacking in this important nutrient.
Selenium is a trace mineral, which means that
the body needs relatively small amounts of it. In the same way that too little
can cause serious health problems, taking too much selenium can also cause health
problems. Large amounts can be toxic, and selenium supplements, like any other
dietary supplement or medication should be kept well out of the reach of children
at all times.
Dietary supplements have an important role in
overall health and well being, but they must be treated with the respect that
their powerful properties demand. Always take supplements according to the accepted
dosage recommendations, unless you have specific and personalized alternative
dosage instructions from a qualified health care provider.
