Are Trace Mineral Elements Important To Your Health?
Trace elements are those minerals that, although
essential to the processes of the body, are necessary in very small or trace
amounts, unlike other minerals such as calcium, potassium and sodium, which
are among what are called macro-minerals, as we need much larger amounts of
these. While the standard recommended intake level of macro-minerals is usually
more than 100mg per day, the standard recommended daily intake level of trace
minerals is much lower.
Minerals are essential to the functioning of
the body. Literally thousands of enzymes depend upon individual minerals and
combinations of various minerals to perform their tasks. Enzymes are essential
to most biological processes, ranging from digesting food to converting it to
a form cells can use to the creation of the very substances that hold the body
together.
Perhaps the most well known of the trace element
minerals is iron, which came to be recognized as such by Claude Bernard in the
1850's. Iron plays many roles in the body, as it is an essential component of
many enzymes, which perform tasks ranging from transporting oxygen throughout
the body to storing energy and making it available to the body. For adult men,
the standard recommended daily intake level of iron is 10 mg, and for women
it is 15mg.
Zinc came to be recognized by the scientific
community as an essential nutrient around the turn of the 20th century. Zinc,
like all minerals, is a fundamental part of many enzymes responsible for a variety
of bodily functions, including those involved different types of metabolism
processes. Zinc is especially important to the growth of children, sexual maturation,
wound healing, and the sense of taste. It also has antioxidant properties. The
standard recommended daily intake level for adult males is 15mg, and for adult
females it is 12mg.
Selenium was universally accepted as an essential
nutrient in the 1950's and came to be known as having antioxidant properties
in 1973, due to its importance in enzyme processes that bring free radicals
under control. In partnership with Vitamin E, it serves as a powerful antioxidant,
with many studies associating selenium with a reduced incidence of a variety
of different cancers, as well as helping to prevent heart disease. The standard
recommended daily intake level for adult males is 70mg, and for adult females
it is 55mg.
Iodine is another important trace mineral. It
has an essential function to the body, in that it serves to regulate the thyroid,
which controls many of the body functions via hormone production. Adults need
a mere 150 micrograms daily. Without it, however, serious health consequences
can occur.
Other essential trace elements include chromium,
which is necessary to many important functions within the body, such as sugar
metabolism and the regulation of blood sugar levels, as well as for the transportation
of amino acids. Copper and manganese are two more that have essential roles
in important antioxidant enzymes. There are several more trace elements that,
although required in minute amounts, serve the body in many important ways.
One of most common ways these minerals are ingested is through plants that have
been grown in soil that contains these elements. However, as soil quality varies,
so too does mineral content.
Dietary supplements, when taken with care and
attention to standard dosage recommendations, can be a reliable and effective
means of ensuring that you are receiving the right amount of these essential
trace element minerals.
