Meaning Of Cholesterol

What is Cholesterol? Cholesterol is an organic molecule. It is considered both as good and bad.  It is a waxy substance present in our blood which is necessary for various functions of our body. It helps in the production of bile and vitamin D and helps to build healthy cells. It also helps in the production of hormones. 80% of cholesterol is produced by the liver. It is useful for the digestion of fats. Cholesterol doesn't dissolve in water. Particles, called lipoprotein, help cholesterol to travel through the blood vessels.

Lipoproteins are of two forms:

  1.  LDL(Low-Density Lipoproteins).

  2.  HDL(High-Density Lipoproteins).

LDL or Low-Density Lipoproteins is also known as bad cholesterol and is the result of a high deposition of fats in the blood vessels. Excess intake of fatty and saturated fat food items leads to high cholesterol. The liver produces 1000 mg of cholesterol daily which is enough for our body to function normally. Excess consumption of fatty, oily, saturated fat boost the cholesterol level and build an obstacle for the blood to pass through the arteries. It results in various health issues mainly heart diseases such as heart attack and stroke.

Cholesterol is very essential for the normal functioning of our body, but all the benefits are put to waste when the level of cholesterol increases in the blood.

HDL or High-Density Lipoproteins is Good Cholesterol. Its function is to carry cholesterol from the whole body to the liver and then the liver removes it.
