Cholesterol is a
necessary component of the cells in the body. It is found in large quantities
in nerve tissue, the brain, skin, adrenal glands, and liver. Cholesterol is a
soft, fat-like substance found in the bloodstream along with the circulating
fats called lipids. Cholesterol is not able to dissolve in blood and in order
to be transported it must be united with a type of
Low Density
Lipoprotein (LDL) is known as bad cholesterol when found in large quantities.
It contains more cholesterol than protein and helps transport cholesterol to
the cells. When the LDL level is high, excess cholesterol will accumulate in
the blood vessels and lead to
complications.
High Density
Lipoprotein (HDL) is known as good cholesterol because it contains more protein
than other cholesterol. This form of lipoprotein helps transport excess
cholesterol away from the cells, therefore, it is better to have more HDL’s and
fewer LDL’s in the bloodstream.
When there is too
much cholesterol circulating in the blood, it leads to a disease called
hypercholesterolemia. This elevated level of cholesterol in the blood will
eventually lead to the formation of fatty deposits of plaque on the lining of
blood vessels. When this happens, blood vessels become narrowed and hardened by
these deposits. This condition is called atherosclerosis and it can lead to the
formation of blood clots in these now narrowed blood vessels. When blood
vessels become narrowed, it makes it difficult for blood to reach parts of the
body and can eventually cause serious damage.
It is believed that atherosclerosis causes more deaths due to heart
attacks than any other disease.
A diet high in
cholesterol can lead to stroke, heart disease, atherosclerosis, and possibly
death. Many of the great tasting foods that we eat every day contain high
amounts of cholesterol. Foods that are high in cholesterol include red meat,
egg yolks, whole milk, cheese, ice cream, butter, fried foods, cake, and
cookies. Foods that are prepared with high amounts of saturated fats such as
palm or coconut oil also lead to high cholesterol levels.
Foods that are
low in cholesterol and high in fiber are a smarter choice. These include fresh
leafy vegetables, peas, dried beans, and whole grains. A healthy diet is one
that contains less red meat and more fish and poultry. Taking the skin off
poultry makes it even healthier to eat.
Other factors
that can lead to high cholesterol include smoking, obesity, and a family
history of heart disease.
The American
Heart Association says that when the level of cholesterol rises above 200
milligrams per deciliter of blood, there is a significant increase in the risk
of having a heart attack. High cholesterol can vary from person to person but
is generally defined as above 240 mg/dl.
The body has the
ability to produce approximately 1,000 milligrams of cholesterol daily from the
carbohydrates and fats that we eat. Therefore, it is not necessary to eat foods
that are high in cholesterol in order to meet the body’s needs. In fact, the
American Heart Association recommends that you limit your daily intake of
cholesterol to no more than 300 milligrams per day. The daily diet should
contain no more than 30% fat and only a third of this fat should be saturated.
Exercise and a
healthy diet are two ways that you can lower your cholesterol. It is important
to always consult a physician before starting any diet or exercise plan. Stress
management is also very helpful in reducing the risk of heart disease, heart
attack, and stroke. In many cases where cholesterol levels are not being
controlled, it may be necessary for a physician to prescribe medication to help
lower it.
