Minerals: Why We Need
Them For Better Health
MINERALS are basic elements found in the soil. Plants pick
up these elements naturally. When we eat these plants [or
animals who have eaten the plants], we absorb these minerals
into our own tissues.
SODIUM, POTASSIUM, MAGNESIUM and CALCIUM are minerals the
body requires in large amounts, the focus of this report will
be on these four minerals. There are many other minerals the
body uses but the amounts are very small.
SODIUM, known as salt, regulates the water distribution in
our bodies. Salt is the most abundant mineral in our blood
and active people need it. Low salt levels will cause dehydration
and muscle cramps.
This does not mean piling on extra salt while cooking or
eating, we get enough salt depending on the foods we eat.
Meat, fish, chicken, grains, and nuts contain salt.
Other foods high in salt: milk and margarine [except those
advertised as low salt], canned foods, ketchup, popcorn, potato
chips, french fries and sauerkraut.
According to a Harvard Medical School study, all our body
requires is 0.2 grams of salt per day. Too much salt causes
dehydration, potassium loss and serious medical problems.
POTASSIUM is a mineral that controls muscle heat and nerve
conduction [the transmission of nerve impulses]. When we exercise
and feel weak and tired, it's usually low mineral levels in
muscle cells. Lack of Potassium is a common cause and there
is no warning system to tell you this, unless a blood test
is performed.
When exercising, muscle produces heat; Potassium released
by the muscle prevents overheating by increasing blood flow.
Sweat and urine excrete Potassium so replacing it is vital.
Fruit juices have high levels of Potassium, drinking generous
amounts will replenish low levels of this mineral. Other Potassium
rich foods are: fruits and vegetables, molasses, pecans, rye,
flour, soy beans, walnuts and wheat germ.
MAGNESIUM helps to control muscle contraction and regulates
the conversion of carbohydrates to energy. Low magnesium levels
cause fatigue and muscle cramps.
A U.S. Department Of Agriculture report states that 36% of
Magnesium is supplied through dairy products and meat. Other
recommended foods are dark bread, nuts, and green leafy vegetables.
Believe it or not, beer is a great source of magnesium. Some
professional athletes have been known to hit the beer cooler
as a post game recovery drink.
CALCIUM is the most abundant mineral and the main structural
material for bones and teeth. Calcium controls muscle contraction
and regulates most of the chemical reactions in our body.
Unless you are growing, pregnant or nursing, calcium requirements
are low. If your body needs calcium, your own bones will supply
it.
Sources of calcium: almonds, asparagus, beans, cabbage, cauliflower,
cheese, egg yolk, figs, lentils, milk, nuts, sardines and
turnip greens.
Combining these four minerals into your daily diet will increase
energy levels and add some snap to your exercise routine!
