Cholesterol: how to lower cholesterol
Cholesterol: how to lower cholesterol

Why bother?
Heart disease is the number one killer in Australia.
It is mainly caused by clogging up of the arteries by a
fatty substance known as atheroma, which comes from
having too much ‘fat’ in the blood.
This serious process is called atherosclerosis—the condition
that can lead to heart attack or stroke.
There are two types of fat that cause damage if their levels are
too high—cholesterol and triglyceride.
A special blood test taken after
fasting for at least 12 hours
can tell if one or both of these fats are too high.
Triglyceride
If your triglyceride level is too high, fixing the problem is
usually quite straightforward because it is mainly due to
being overweight.
It is caused by having too many
calories in the diet, especially
from sugar and other carbohydrates and high-calorie drinks
(e.g. soft drinks and alcohol, in particular beer).
The aim is to get your weight down to an ideal level.
Cholesterol
High cholesterol is a bigger problem, and if your level
is too high it is important to reduce it. Cholesterol is a
white fatty substance made mainly in the liver by animals,
including humans. We get high levels mainly through
our diet, by eating saturated fats especially from animal
foods (therefore it is a rare problem in vegetarians) and
trans-fats found mainly in processed products.
There are 2 main types—HDL ‘good’ cholesterol and LDL ‘bad’
cholesterol. We aim to raise HDL and lower LDL. Most
people can lower the level through changing their diet.
Occasionally the level is so high in some people that,
in addition to the diet, special medicine is necessary
to reduce it to the right level. The prescribed drugs are
very effective.
Note: Although cholesterol is present in animal food, it
has been shown that it is necessary to reduce the amount
of all the saturated fats (plant and animal) in our diet
and to lose excess weight in order to get our cholesterol
down.
Foods rich in starch (such as bread, rice and pasta)
and foods rich in starch and fiber, known as complex
carbohydrates, also help.
