Nutrition - Cholesterol

Cholesterol doesn't mix with the watery action of blood as it is a lipid. Lipoproteins are protein-based carriers that the body has developed. This fully closes in lipids for transport in the blood.

There are 3 important lipoproteins, these are:

VLDL - (very low density lipoproteins)
LDL - (low density lipoproteins)
HDL - (high density lipoproteins)

VLDL contains triglycerides and also cholesterol, it's also synthesised by the liver and transports triglycerides into the adipose tissue.

LDL is formed from VLDL. This happens when most of the triglycerides have been unloaded. It then transports the rest of the cholesterol to the different cells in the body that need them.

HDL transports excess cholesterol from the tissues and also the blood back to the liver. This is also synthesised by the liver.

Increased levels of LDL cholesterol and HDL cholesterol that is lower than 25% as well as triglycerides can increase the risk of circulatory and heart problems. 5.2mmol/dL was shown to be the recommended upper limit of fully cholesterol is the 1980's. Levels above this figure can cause lifestyle changes and medications like statins to the lower plasma cholesterol.
