Selenium is a micronutrient/mineral, or what is more commonly referred to as a trace mineral.
It is typically found in the
soil, and is theoretically absorbed into a plant as it grows,
which eventually benefits us as we eat these plants. It’s found
in higher amounts in certain areas around the globe than others,
but if the soils that vegatables are grown in are depleted, the
plant will be depleted. So that means that the amount found in
foods can vary greatly. It is for the most part classified as an
antioxidant and is equated in its action to vitamin E. Selenium
is incorporated into proteins to make what are known as
selenoproteins, which are part of antioxidant enzymes. This
antioxidant property helps to prevent cellular damage caused by
free radicals. Free radicals are natural by-products of
oxygen/food metabolism that can contribute heavily to the
development of chronic diseases such as cancer and heart
disease.
Full blown deficiencies of selenium are fairly rare in the
United States, but they are seen in other third world countries
like China, where the soil concentration of selenium is notably
low. What is prevalent and more typically found in our ‘modern
society’ is what are known as ‘subclinical’ deficiencies. These
are diseases where symptoms can be caused by low levels in the
blood e.g. digestive disorders, but to date have not been
directly linked to the deficit. There is also evidence that
selenium deficiency does not usually cause illness by itself.
Rather, it can make the body more susceptible to illnesses
caused by other nutritional stresses.
A few of the more serious diseases that are associated with
selenium deficiency include:
1. Keshan Disease, which results in an enlarged heart and poor heart function, occurs in selenium deficient children.
2. Myxedematous Endemic Cretinism, which results in mental retardation.
3. Kashin-Beck Disease, which results in bone disorders.
As stated, selenium depletion or deficiency can lead to, and be
associated with severe gastrointestinal problems such as Crohn's
disease and other gastrointestinal disorders. What happens is
that it ends up being a chicken and egg situation, first there
may be a deficit that causes the problem. And then it becomes
worse because the body begins to loose the ability to absorb
nutrients because of the damage the deficit causes. Those with
acute severe illness’s who develop inflammation and widespread
infection often have decreased levels of selenium in their
blood. Unfortunately not many doctors have made the connection
between the deficiency and the pathologies that manifest because
of the lack of this nutrient.
Another benefit from having enough selenium in the system is
that it can also help to regenerate of the liver after it has
been damaged. In a lesser known application, it can help in the
prevention and treatment of dandruff! And it has been known to
neutralize some carcinogens and can provide protection from some
types of pathologies that are affected by these precancerous
conditions.
Recommended Daily Allowances for Selenium:
Men - 70 mcg
Women - 55 mcg
Children - 20 - 30 mcg
Selenium is classified as an essential trace mineral in the
human body. This nutrient has gained a tremendous amount of
recognition over the past ten years, with many studies being
performed that show its efficacy. Selenium is also essential for
normal functioning of the thyroid gland, which has far reaching
ramifications for those who are trying to loose weight. They get
caught up in the viscous cycle of binging on junk food that is
totally devoid of any real nutrient content, that even further
robes their bodies of nutrients like selenium that help to
maintain their health and well being.
Almost all main stream medical intervention is about treating
the symptoms, and not the cause of a disease. Many times in the
field of medicine the answer is right in front of us, but we
can’t see it, taking selenium to supplement your diet may fend
off any possible lack of this nutrient that may be occurring and
causing you to feel less than at your peak! †
