Watch Blood Cholesterol by: devika


Blood Cholesterol- Good and Bad



Cholesterol, a yellowish fatty substance, is one of the essential ingredients of the body. Although it is essential to life, it has a bad reputation, being a major villain in heart disease. Every person with high blood cholesterol is regarded as a potential candidate for heart attack or a stroke. 

Most of the cholesterol found in the body is produced in the liver. However, about twenty to thirty per cent generally comes from the food we eat. The normal level of cholesterol varies between 150 - 200 mg per 100 ml. In blood, cholesterol occurs in combination with certain lipids (fats), hence, known as lipoptroteins. 

There are two main types of lipoproteins: a low density one (LDL) and a high density one (HDL). The low density lipoprotein is the one which is considered harmful and is associated with cholesterol deposits in blood vessels. 

The higher the ratio of LDL to the total cholesterol, the greater will be the risk of arterial damage and heart disease. HDL, on the other hand, plays a salutory role by helping remove cholesterol from circulation and thereby reducing the risk of heart disease.

Causes:

Hereditary:
Hyper cholesterolaemia or increase in cholesterol is mainly a hereditary disorder.

Excessive consumption of rich foods:

It is also caused by taking rich foods and fried foods: excessive consumption of milk and its products like clarified butter, butter, and cream; white flour, sugar, cakes, pastries, biscuits, cheese, and ice cream; and non-vegetarian foods like meat, fish, and eggs.

Smoking, Drinking and Stress:

Other causes of increase in cholesterol are irregularity in habits, smoking and drinking alcohol. Stress has also been found to be a major cause of increased level of cholesterol.
