What is cholesterol?
Cholesterol is an important element in the formation of cellular membranes, hormones, vitamin D and bile.
A high level of cholesterol (total cholesterol over 5.2 mmol/L) is a good risk indicator for developing arteriosclerosis, hypertension, heart problems, strokes and gallstones.
HDL (high-density lipoprotein) is a kind of vesicle that transports fats (including cholesterol) from the cells to the liver, where the excess can be eliminated through bile. HDL is usually considered an indicator of “good cholesterol”.
LDL (low-density lipoprotein) transport fats from the digestive tract to the cells, and is likely to contribute to the accumulation of plaques on the blood vessel walls. It is considered a good indicator of “bad cholesterol”.
