DietDefining and understanding cholesterol metabolism requires some background knowledge of anatomical processes. The causes, effects, and possible ways to solve the problems should also be discussed. First of all, what is cholesterol? Medical dictionaries explain that this fat normally found in blood, results from eating animal-based foods. This substance is processed by the liver and it is an essential building block for healthy cells and nerves while it also serves to producing some hormones. However, you should be careful about the growth of cholesterol levels, since high concentrations can lead to atherosclerosis and coronary artery disease (CAD), as well as heart attacks. Otherwise, this body fat is useful in moderate concentrations.

The other notion to present in connection with cholesterol metabolism is obviously metabolism. Metabolism is the sum of all chemical processes that take place in the body. To go a little bit further with the explanation, you should be aware of the two types of metabolism that exist: anabolism builds up while catabolism breaks down. In the case of anabolism smaller molecules such as amino acids are turned into larger molecules like proteins. Obviously catabolism involves the reversed process, large molecules break into smaller ones, thus glycogen becomes glucose.

Cholesterol metabolism consists of the sum of the catabolic and anabolic processes that synthesize and break the cholesterol in the system. Serum cholesterol level increases when it is ingested and very quickly absorbed. Besides the liver, almost all the other body tissues can synthesize cholesterol. The more cholesterol is taken in, the less it gets synthesized by the body. The cholesterol removal from the body is done by bile excretion after it is broken down in the liver.

High cholesterol is also caused by a sum of factors that increase the risks for one’s Health. Thus, A sedentary life style, an improper Diet, a genetic predisposition, topped by weight gain turn into an extreme drawback for cholesterol metabolism. High blood pressure, diabetes, hypothyroidism and other Health problems can also be a cause for high cholesterol levels. In some cases the Health problems result simply from the incapacity of the liver to process too much cholesterol. If you have a family history of high cholesterol, watch your Health more carefully. Unfortunately it is a lot more difficult to fight against genetic predisposition by simply sticking to diets. However there are medicines that can help. In other situations, a proper Diet and a lot of physical activity can do much good.
