The types of Cholesterol
Cholesterol or lipids (fats) are transported around the body on protein molecules called Lipoproteins. An increased in blood cholesterol (particularly LDL and triglyerides) has been associated with a greater risk of heart disease. In Australia, Lipid lowering drugs are currently the highest expenditure of all drugs. Modifying cholesterol does at times need medicating, however lifestyle (managing stress and exercising) and diet can play a dramatic role keeping it low.
HDL – high density lipoproteins are cardioprotective (protect your heart) and focus can be on raising these
LDL – low density lipoproteins are have a higher fat:protein ratio and are considered bad cholesterol
Triglyceride – fat ingested from diet, is considered to be bad cholesterol and is often elevated in diabetics.
(There are other forms of cholesterol, however the 3 mentioned above are the most commonly measured in blood tests.)

National Heart Foundation (2001) recommends:

LDL
< 4.0 mmols/L high risk
<>

HDL
> 1.0 mmols/L all
> 1.0 mmols/L all

Triglycerides
< 2.0 mmols/L all
<>

Total Cholesterol
< 6.0 mmols/L low risk
< 4.0 mmols/L high risk

Lowering Cholesterol
