All about
Minerals
What are minerals? These are naturally
occurring substances found in rocks and earth soil, which have
their characteristic appearance and chemical composition. The
primary functions of minerals are:
They form constituents of the skeleton.
They control the composition of body
fluids
The play important adjunctive role in
the assimilation of many enzymes and their proteins.
Calcium, magnesium, potassium, selenium,
zinc, and chromium picolinate are some of the important minerals
about which we would discuss here.
Calcium
Calcium is an indispensable mineral for
healthy bones and strong teeth. Its other attributes include
ensuring optimum muscle and nerve functioning and helping in blood
clotting. Calcium is very essential for growing children. Foods
which are rich in calcium are milk, cheese, eggs, dairy products,
fruits, green vegetables, almonds, seaweeds (such as kelp, wakame
and hijiki), nuts, beans and pulses, breads and fish. Calcium
deficiency states can impact bone and teeth formation while any
excess calcium in the body could result in kidney stones.
Magnesium
This mineral is needed for maintaining
muscles, nerves and bones. It plays an important role in
maintaining the rhythm of the heart, energy metabolism as well as
protein synthesis.
Spinach, nuts, seeds, whole grains, water,
fruits and vegetables provide rich sources of magnesium. Its
deficiency results in a large number of disease conditions
including sensitivity to noise, nervousness, irritability, mental
depression, confusion, twitching among others.
Potassium
This is involved in maintaining the fluid
balance in our body. it effectively controls the activities of the
heart, muscular and nervous system of the body and is present in
almost every cell of the body. The water and acidity balance of
the blood and tissues is kept in optimum condition by this
mineral. Interestingly, our bodies carry more than twice the
amount of potassium as sodium. Bananas, orange juice, breads,
cereals and other grain products can provide us with loads of
potassium. Weakness and malfunctioning of the muscles are caused
by potassium deficiency while any excess of potassium can cause
irregularity of heart beats.
Selenium
This mineral performs largely as a protein
called seleno-proteins which act as enzymes. This can prevent cell
damages caused by environmental oxidants or which are caused by
normal metabolism. Seafood, some meats (such as kidney and liver),
some grains and seeds are good sources for Selenium. Its
deficiency results in a disease condition called ‘Keshan’ disease
which is fatal. It is a disease of the heart muscles. Excess
amounts of this mineral can cause permanent balding and brittle
nails. The deficiency state also results in a garlic odor in
breath and intestinal distress, weakness and slowed mental
functioning.
Zinc
This mineral is essential for protein
product and cell division in the body. It is related closely to
the sense of smell and is a component of insulin. Eggs, cereals,
meat, liver, seafood and nuts are good sources of zinc. Zinc
deficiency can result in a short stature of the individual, dark
skin, enlarged liver and spleen, impaired sexual or reproductive
function, slow wound healing and immune deficiency. Any excess of
this mineral could cause upset stomach and cause copper deficiency
states.
Chromium Picolinate
Playing a critical role in the
carbohydrate and fat synthesis, this mineral works in conjunction
with insulin, helping the cells to absorb glucose and release
energy, which enables us to perform all activities.
Meats, whole grains, fruits and vegetables
as well as vegetable oils are abundant sources for this mineral
Anxiety, fatigue, glucose intolerance
(particularly in people with diabetes), inadequate metabolism of
amino acids, and an increased risk of arteriosclerosis are some of
the negative outcome when we run a deficiency state for this
mineral.
