Cholesterol: Good or bad?
The importance of cholesterol and its essentiality is examined. Cholesterol is transported within the human organism by lipoproteins (chylomicrons, VLDL, LDL and HDL).The LDL, considered “bad cholesterol”, transport cholesterol from the liver to other tissus for their needs. However, HDL, the ”good cholesterol ”, transport back cholesterol to the liver to be recycled.Therfore, cholesterol is rather good for its various functions in the organism, and its deficiency may lead to cellular damage and a reduction in the synthesis of hormones such as testosterone and also vitamin D. Hypercholesterolemia should be considered an indicator of a health problem within the cells, that the organism is trying to fix by mobilizing cholesterol.
