Well Atul,

Cholesterol is a waxy, fat-like substance that is made in the body by the liver. Cholesterol forms part of every cell in the body and serves many vital functions. Our bodies need cholesterol to:

* Maintain healthy cell walls

* Make hormones Chemicals produced by an organ or part of the body and carried in the bloodstream to another organ or body part to affect its function; different hormones have difference effects on the body. (the body's chemical messengers)

* Make vitamin D

* Make bile acids, which aid in fat digestion

Sometimes, however, our bodies make more cholesterol than we really need, and this excess cholesterol circulates in the bloodstream. High levels of cholesterol in the blood can clog blood vessels and increase the risk for heart disease and stroke.

* Our bodies can make too much cholesterol when we eat too much saturated fat - the kind of fat found in animal-based foods such as meat and dairy products.

* In addition to making cholesterol, we also get a small percentage of our body's cholesterol from the foods we eat. Only animal-based foods such as meat, eggs, and dairy products contain cholesterol A fat-like substance that can deposit on the artery wall, narrowing or blocking blood flow.. Plant foods such as fruits, vegetables, and grains do not contain cholesterol.

CHOLESTREOL IS A fat-like substance that is made by the body and is found naturally in animal foods such as meat, fish, poultry, eggs, and dairy products. Foods high in cholesterol include liver and organ meats, egg yolks, and dairy fats. Cholesterol is carried in the blood. When cholesterol levels are too high, some of the cholesterol is deposited on the walls of the blood vessels. Over time, the deposits can build up causing the blood vessels to narrow and blood flow to decrease. The cholesterol in food, like saturated fat, tends to raise blood cholesterol, which increases the risk for heart disease. Total blood cholesterol levels above 240 mg/dl are considered high. Levels between 200-239 mg/dl are considered borderline high. Levels under 200 mg/dl are considered desirable.

Hello atul

Cholesterol is a type of fat found in your blood.

Your liver makes cholesterol for your body. You also can get cholesterol from the foods you eat. Meat, fish, eggs, butter, cheese, and whole or low-fat milk all have cholesterol in them.
You need some cholesterol to help your brain, skin, and other organs grow and do their jobs in the body. But eating too much of it is a bad idea, especially for people whose bodies already make too much cholesterol.

It is a type of fat contained in the blood.There are two types(1)Dietary cholesterol and (2) Blood or 'Plasma'cholesterol.The first is contained in the food and the second in body metabolism.
Each day the liver produces up to 1gm of blood cholesterol,the fat like waxy material that is component of all body cells.Blood cholesterol is also involved in the creation of some hormones and helps to make Vitamin D,and bile acids,which aids digestion.

Cholesterol is technically a solid alcohol . The required amount of cholesterol is produced in the liver itself . Cholesterol is again divided into good cholesterol and bad cholesterol . Well bad cholesterol will stick to artery and narrow it down and cause lot of problems. Cholesterol is a source for cartilage growth in the body.

EXCESSES WILL CAUSE HEART PROBLEMS.
