CHOLESTROL
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. Cholesterol is measured in milligrams per 100 millimetres of blood. 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.
It is also caused by taking rich foods and fried foods: excessive consumption of milk and its products like ghee, butter, and cream; white flour, sugar, cakes, pastries, biscuits, cheese, and ice cream; and non-vegetarian foods like meat, fish, and eggs.
Lecithin, also a fatty food substance and the most abundant of the phospholipids, is beneficial in case of increase in cholesterol level. It has the ability to break up cholesterol into small particles which can be easily handled by the system. With sufficient intake of lecithin, cholesterol cannot build up against the walls of the arteries and veins. Lecithin also increases the production of bile acids made from cholesterol, thereby reducing its amount in the blood, Egg yolk, vegetable oils, wholegrain cereals, soyabeans, and unpasturised milk are rich sources of lecithin. The cells of the body are also capable of synthesizing it as needed, if several of the B vitamins are present. The amount of fibre in the diet also influences the cholesterol levels and LDL cholesterol can be lowered by taking diets rich in fibres. The most significant sources of dietary fibre are unprocessed wheat bran, whole cereals such as wheat, rice, barley, rye; legumes such as potatoes, carrots, beet, and turnips, fruits such as mangoes and guavas; and leafy vegetables such as cabbage, lady’s fingers, lettuce and celery. Oat bran and corn bran are specially beneficial in lowering LDL cholesterol.
To reduce the risk of heart disease, it is essential to lower the level of LDL and increase the level of HDL. This can be achieved by a change in diet and lifestyle. As a first step, foods rich in cholesterol and saturated fats, which lead to an increase in the LDL level, should be reduced to the minimum. These foods are eggs, organic meats, cheese, butter, bacon, beef, and whole milk.
