Cholesterol is a word that people hear almost everyday. Although most people often associate this with fatty food, which gives it a negative connotation, cholesterol is a very important substance that has several functions in the body.

Cholesterol is the fatty and waxy lipid solution produced in the body that provides protective coating to the arteries and their surrounding walls; it also keeps the cell membranes of the body intact. This is considered the best source of fertility, vitality, libido, and energy. Aside from this, it also aids in digestion and supports the nervous system at the time of sleep. However, despite these important functions, cholesterol can pose a threat once it reaches high levels.

Generally, cholesterol is carried in packages through lipoproteins that are broadly divided into two categories: the High-Density Lipoproteins, or HDL, and the Low-Density Lipoproteins, or LDL.

HDL is considered the good cholesterol because it helps prevent the harmful build-up of LDL on the walls of the arteries. It also provides energy and fulfills the fat requirements of the body. Because of these advantages, there should be more HDL in the bloodstream. This can be achieved by staying active, getting regular exercise, eating a balanced diet, and avoiding foods rich in saturated fats.

LDL, on the other hand, is bad cholesterol because it tends to accumulate in the walls of the arteries, thus forming plaque that can lead to serious problems such as stoke and heart attack. The body needs only a little of LDL, which is why it is necessary to reduce high levels of LDL in the body. This can be done by avoiding foods which are high in saturated fats and trans-fatty acids such as meats, egg yolks, milk dairy products, candy bars, and fast food.

Cholesterol is not a bad substance. The body needs an ample level of cholesterol to perform its daily functions. However, too much of the wrong kind of cholesterol can prove fatal.
