Hello I am a biochemist that suffers from high cholesterol. The first thing to know is that no one knows exactly what causes atherosclerosis, a condition in which an artery wall thickens as the result of a build-up of fatty materials such as cholesterol. It seems that cholesterol plays a part in the disease process but not the only part.
What is cholesterol anyway? cholesterol is a lipid fatty substance that is produced by your liver and released to your blood it has many important functions in your body that cannot be done by any other substance it is part of the membrane of cells which gives them their elasticity.
Cholesterol cannot be transported in the blood as is, since it's a fatty substance that is not soluble in water. Therefore it carried by special proteins carriers. There are several such carriers, but the most known are Low density lipoprotein (LDL) and high density lipoprotein (HDL). Both manufactured by the liver and have a role in regulation of cholesterol and other fats. LDL is called the bad fat because it accumulates in the arteries.
Fats consumption in your diet does affect the ratio between LDL and HDL.
Fats that especially affect your LDL are Tran fatty acids. Trans fatty acids are fats that occur only on trace amounts in nature. The Trans fats in our diet are from an industrial process, unfortunately our body cannot process this kind of fat and research shows that trans fats affect proper function of the liver which results in higher LDL in the blood.
