Potassium
A human body powered by
electricity ... you may think that sounds like something out of a science
fiction story. Well, there have been science fiction stories written about
electrically powdered human bodies. But, guess what ? Electrically powered
humans aren't so far-fetched as they might seem. If you want to see one, go
look in the mirror.
Potassium and sodium chloride are
the two essentials that let you literally become a walking power plant. Your
body's electricity is similar to the regular electricity that illuminates
light bulbs. Too little voltage (potassium) and the light (your body) won't
work. Too much voltage (potassium) and you destroy the object (your body)
you're trying to electrify.
The mineral potassium is an
electrolyte, which means that in water the mineral completely dissolves into
separate components called ions that conduct electrical charges. Potassium
is a positively charged ion.
The body also contains sodium and
chloride, both of which are electrolytes and conduct electrical charges,
too. Sodium is also positively charged, while chloride is negatively
charged.
Potassium, sodium, and chloride
work together by way of their positively and negatively charged electrons to
maintain fluid balance inside and outside your body's cells. This
arrangement, which works like a tiny battery, creates enough electricity to
let nutrients and waste products in and out of your cells. Your body's
"battery" is essential for maintaining normal function of your heart, brain,
muscles, and kidneys.
In addition to providing your
body's battery with what it needs to function, potassium also inhibits the
formation of free radicals, which further slows down the aging process.
Breaks you out of the bone
loss cycle. Several studies indicate that getting plenty of
potassium may reduce the los of calcium from your body. Keeping all the
calcium you can in your body is essential for maintaining strong bones.
Puts the brakes on high
blood pressure. Since the 1920s, various studies have observed
potassium's potential for lowering blood pressure, especially in people who
tend to have high blood pressure. Lower blood pressure means a lower risk of
heart attack and stroke. even in people with perfectly normal blood pressure
levels, a serving or two of fresh fruit and vegetables every day can reduce
the risk of stroke.
In people with high blood
pressure, the power of potassium is even more amazing. Not only does a
little extra potassium in the diet significantly lower the blood pressures
of people taking high blood pressure medicine, it also reduces the need for
blood pressure medicine at all.
African Americans respond
exceptionally well to potassium's blood pressure lowering effects. This may
be partially due to their tendency to eat fewer foods containing potassium
than other people.
Makes sure the beat goes on.
Potassium is critical for maintaining your heartbeat. Too little potassium
can lead to arrhythmias, or heartbeat irregularities, which may be fatal.
This is especially true for people taking digitalis. In addition, the sudden
deaths attributed to fasting as thought to be caused by potassium loss.
Maximizes muscle power.
Your body must have potassium for your muscles to contract. Too little
potassium can cause muscle weakness, cramps, restless legs, progressive
muscle loss and, eventually, even paralyze your respiratory system.
Kicks kidney stones.
Low potassium leads to less acid in your urine, a condition that favors the
development of kidney stones. Plenty of potassium in your diet can prevent
this painful problem.
