Cholesterol is then attracted to this ?rough? site on the blood vessel wall in an attempt to heal the wall so that blood will flow smoothly over the injured area. No research has ever shown cholesterol building up on a healthy blood vessel and slowly clogging it just as a sewage pipe might over time. Cholesterol is a waxy substance found only in animals or animal products (meat, cheese, eggs). It is actually manufactured inside our bodies. Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver , spinal cord and brain . It plays a central role in many biochemical processes, such as the composition of cell membranes and the synthesis of steroid hormones .

Cholesterol is transported around the body in the blood attached to a protein. This combination of fat and protein is called a lipoprotein. Cholesterol is a common name for four kinds of substancies: two types of lipoproteins, triglycerides and Lp(a) cholesterol. Lipoproteins are used to transport cholesterol to and from your bodys cells. Cholesterol is constantly synthesized in the body, mainly in the liver and the kidneys. Most of the cholesterol present in the body is synthesized in the liver, but a proportion is also absorbed from the diet of fat-rich foodstuffs like animal fats and oils, milk, and yolk of egg.

LDL cholesterol is the main source of build-up on the blood vessel walls. HDL cholesterol carries cholesterol back to the liver and prevents build-up on the blood vessel walls. LDL is also referred to as "bad" cholesterol because it is the form of this fat that is linked to heart disease. HDL is referred to as " good cholesterol " because it helps remove LDL cholesterol from the blood. LDL cholesterol, known as bad cholesterol, can build up on artery walls. HDL cholesterol, known as good cholesterol, takes cholesterol into the liver, where it is removed from the body.

Blood pressure, glucose tolerance, fatty acid profile, and cholesterol levels were measured at baseline and after 16 weeks on the diets. Blood is watery, and cholesterol is fatty. Just like oil and water, the two do not mix. Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic).

Lowering LDL in early life (lifestyle changes may be sufficient) aims to prevent or slow down plaque formation. Once symptoms (eg angina) are experienced, the disease is already established. Lowering your blood cholesterol level is one of the best ways you can decrease your risk of heart disease. And, even if your cholesterol is close to the desirable range, 200 milligrams per deciliter of blood, you can lower it and reduce your risk of heart disease. Lowering the LDL to less than 80-100 is also felt to be beneficial in minimizing the toxicity of Lp(a).

Fats are classified as saturated or unsaturated (according to their chemical structure). Saturated fats are derived primarily from meat and dairy products and can raise blood cholesterol levels. Fats should contribute no more than 20 to 35% of your daily calories. Less than 7 to 10% of your calories should come from saturated fat. Fat provides a terrific source of energy as well as a great depot for storing it. It is an important part of cell membranes, helping govern what gets into cells and what comes out.

Triglycerides are another type of fat in the blood. High levels of triglycerides can be harmful. Triglycerides are another type of fatty substance in the blood. They are found in foods such as dairy products, meat and cooking oils.

Dieticians, nutritionists and doctors have been telling us that fat is a killer. Governments have introduced national policies based around its reduction. Dietary cholesterol is found only in animal food products such as meat, fish, poultry, eggs, and dairy products. Few people need to restrict cholesterol from food since the body produces excess blood cholesterol from the fats we eat.
