Manage your blood Cholesterol
Cholesterol can be both good and bad, so it's important to learn
what cholesterol is, how it affects your health and how to
manage your blood cholesterol levels. Understanding the facts
about cholesterol will help you take better care of your heart
and live a healthier life, reducing your risk for heart attack
and stroke. To control your cholesterol, get a cholesterol
screening, eat foods low in saturated fat and cholesterol,
maintain a healthy weight, exercise regularly and follow all
your healthcare professional's recommendations. Cholesterol is a
fatty substance (lipid) found in animal tissue and fat. It is a
Substance manufactured by the liver and other organs and
consumed via animal fat. High-fat diets increase the amount
made. It is believed that high levels lead to collection of
cholesterol in the arteries, possibly leading to serious health
risks. It is a soft, waxy substance. The body makes enough
cholesterol to meet its needs. Cholesterol is used in the
manufacture of hormones, bile acid, and vitamin D. It is present
in all parts of the body, including the nervous system, muscle,
skin, liver, intestines, and heart.
Cholesterol is a peculiar molecule. However, the chemical term
for a molecule such as cholesterol is alcohol, although it
doesn't behave like alcohol. Its numerous carbon and hydrogen
atoms are put together in an intricate three dimensional
network, impossible to dissolve in water. All living creatures
use this indissolvability cleverly, incorporating cholesterol
into their cell walls to make cells waterproof. This means that
cells of living creatures can regulate their internal
environment undisturbed by changes in their surroundings, a
mechanism vital for proper function. The fact that cells are
waterproof is especially critical for the normal functioning of
nerves and nerve cells. Thus, the highest concentration of
cholesterol in the body is found in the brain and other parts of
the nervous system. Because cholesterol is insoluble in water
and thus also in blood, it is transported in our blood inside
spheric particles composed of fats (lipids) and proteins, the
so-called lipoproteins. Lipoproteins are easily dissolved in
water because their outside is composed mainly of water-soluble
proteins. The inside of the lipoproteins is composed of lipids,
and here are room for water-insoluble molecules such as
cholesterol. Like submarines, lipoproteins carry cholesterol
from one place in the body to another. A high blood cholesterol
is said to promote atherosclerosis and thus also coronary heart
disease. But many studies have shown that people whose blood
cholesterol is low become just as atherosclerotic as people
whose cholesterol is high.
Your body produces three to four times more cholesterol than
you eat. The production of cholesterol increases when you eat
little cholesterol and decreases when you eat much. This
explains why the "prudent" diet cannot lower cholesterol more
than on average a few per cent.
There is no evidence that too much animal fat and cholesterol in
the diet promotes atherosclerosis or heart attacks. For
instance, more than twenty studies have shown that people who
have had a heart attack haven't eaten more fat of any kind than
other people, and degree of atherosclerosis at autopsy is
unrelated with the diet.
People with high cholesterol live the longest. This statement
seems so incredible that it takes a long time to clear one
