Dietary
minerals are those chemical elements that are needed by body in smaller amounts
through diet to remain healthy and fit. There are 13 main dietary minerals
which are required for good health. 6 of them are needed in relatively higher
amounts and they’re known as Quantity or
Macro Minerals. The other 7 are required in very small amounts and they’re
called Trace Elements. All these
dietary minerals perform very important functions and their deficiency can
cause severe damage to the body. Brief introduction of these dietary minerals
are given below.
Macro
Minerals
The daily
requirement of these dietary minerals ranges from several hundred to several
thousands milligram per day (mg/day). These include Potassium, Sodium,
Chlorine, Calcium, Phosphorus and Magnesium.
The main
function of both Potassium and Sodium is the regulation of ATP (Adenosine
triphosphate) which is necessary for metabolism. Chlorine is required for HCL
(Hydrochloric Acid) in the stomach. Both Sodium and Chloride are present in table salt as Sodium Chloride.
Calcium and
phosphorus are necessary for bones and teeth health and a balance between them
is necessary for their proper function. Calcium is mostly available in milk and
milk products (cheese, yogurt etc.).
Magnesium
is needed for both ATP function and bones health.
Trace
Elements
The daily
requirement of these dietary minerals is between micrograms to few milligrams
per day. These include Zinc, Iron, Manganese, Copper, Iodine, Selenium and
Molybdenum.
Zinc is
necessary for sexual function, growth, skin health and several other functions.
Its higher amounts are present in animal foods and few plant sources.
Iron is
required for the production of RBCs (Red Blood Cells) which carry oxygen to all parts of body.
Liver, meat and green vegetables are good natural sources of Iron.
Manganese
is important for metabolism of amino acids, carbohydrates and cholesterol.
Copper deficiency
can cause bones diseases, cardiovascular diseases, colon cancer and other
disorders. Sea foods, liver, whole grains and chocolate are best sources of copper.
Iodine is
necessary for production of thyroid hormones and its deficiency can cause goiter,
mental retardation and other diseases. Sea foods are the best source of Iodine
and its deficiency is common in areas with low Iodine level in soil. Iodine
addition in table salt is used in these areas to overcome its deficiency.
Selenium and
Molybdenum are also important trace elements for different body functions.
Precautionary
Measures
All these
dietary minerals either macro minerals or trace elements are absolutely
necessary for regular and healthy function of human body and their necessary
amount should be taken through diet but if these minerals are taken in excess
to their upper limit then they can also cause several diseases. Therefore, supplementation
of these minerals should be avoided unless a medical practitioner advises you
for this.
Apart from
that, few people can’t absorb the dietary minerals present in
supplements. Also in this case, natural sources are best choice and many of
them also contain reasonable amount of these dietary minerals and their proper
intake can prevent deficiency of dietary minerals.
