High Blood Cholesterol

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 a high blood cholesterol is regarded as a potential candidate for heart attack, a stroke or high blood pressure.
Cholesterol is a building block of the outer membrane of cells. It is the principal ingredient in the digestive juice bile, in the fatty sheaths that insulate nerves and in sex hormones, namely, estrogen and androgen. It performs several functions such as transportation of fat, providing defense mechanism, protecting red blood cells and muscular membrane of the body.
Most of the cholesterol found in the body is produced in the liver. However, about 20 to 30 percent generally comes from the foods we eat. Some cholesterol is also secreted into the intestinal tract in bile and becomes mixed with the dietary cholesterol. The percentage of ingested cholesterol absorbed seemed to average 40 to 50 percent of the intake. The body excretes extra cholesterol from the system through bowels and kidneys.
The amount of cholesterol is measured in milligrams per 100 millimeters of blood. Normal level of cholesterol varies between 150- 250 mg. per 100 ml. Persons with atherosclerosis have uniformly high blood cholesterol usually above 250 mg. per 100 ml. In blood, cholesterol is bound to certain proteins - lipoproteins which have an affinity for blood fats, known as lipids. 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 the risk of arterial damage and heart disease. The HDL on the other
hand plays a salutary role by helping remove cholesterol from circulation and thereby reduce the risk of heart disease. Cholesterol has been the subject of extensive study by researchers since 1769, when French chemist, Polutier de La Salle purified the soapy-looking yellowish substance. The results of the most comprehensive research study, commissioned by the National Heart and Lung Institute of the U.S.A. were announced about four years ago. The 10-year study, considered most elaborate and most expensive research project in medical history, indicates that heart disease is directly linked to the level of cholesterol in the blood and that lowering cholesterol significantly reduces the incidence of heart attacks. It has been estimated that for every one per cent reduction in cholesterol, there is a decrease in the risk of heart attack by two per cent.
Causes of High Cholesterol
Hypercholsterolaemia or increase in cholestrol is mainly a digestive problem caused by rich foods such as fried foods, excessive consumption of milk and its products like ghee,butter and cream,white flour, sugar, cakes, pastries, biscuits, cheese, ice cream as well as non-vegetarian foods like meat, fish and eggs. Other causes of increase in cholesterol are irregularity in habits, smoking and drinking alcohol.
Stress has been found to be a major cause of increased level of cholesterol. Adrenaline and cortison are both released in the body under stress. This, in turn, produces a fat metabolising reaction. Adrenal glands of executive type aggressive persons produce more adrenaline than the easy going men. Consequently they suffer six to eight times more heart attacks than the relaxed men.
Cholesterol Natural Cures
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 improving the diet and changing the life style. Diet is the most important factor. As a first step, foods rich in cholesterol and saturated fats, which lead to increase in LDL level, should be reduced to the minimum. Cholesterol -rich foods are eggs,organ meats and most cheese, butter, bacon, beef, whole milk, virtually all foods of animal origin
as well as two vegetable oils, namely coconut and palm, are high in saturated fats and these should be replaced by polyunsaturated fats such as corn, safflower, sobayeans and sesame oils which tend to lower the level of LDL. There are monosaturated fats such as olive and peanut oils which have more or less neutral effect on the LDL level.
The American Heart Association recommends that men should restrict themselves to 300 mg. of cholesterol a day and women to 275 mg. It also prescribes that fat should not make up more than 30 per cent of the diet and not more than one third of this should be saturated. The Association, however, urges a somewhat strict regimen for those who already have elevated levels of cholesterol.
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 potato, carrot, beet and turnips; fruits like mango and guava and green vegetables such as cabbage, lady’s finger, lettuce and celery. Oat bran is especially beneficial in lowering LDL cholesterol.
Lecithin, also a fatty food substance and the most abundant of the phospholipids, is highly 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. It also increases the production of bile acids made from cholesterol, thereby reducing its amount in the blood. Egg yolk, vegetable oils, whole grain cereals, soyabeans and unpasteurised 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.
Diet for cholesterol should be high in vitamin B6, cholin and inositol supplied by wheat germ, yeast, or B vitamins extracted from bran have been particularly effective in reducing blood cholesterol. Sometimes vitamin E elevates blood lecithin and reduces cholesterol presumably by preventing the essential fatty acids from being destroyed by oxygen.
Persons with high blood cholesterol level should drink at least eight to 10 glasses of water every day as regular drinking of water stimulates the excretory activity of the skin and kidneys. This in turn facilitates elimination of excessive cholesterol from the system. Regularly drinking of coriander (dhania) water also helps lower blood cholesterol as it is a good diuretic and stimulates the kidneys. It is prepared by boiling dry seeds of coriander and straining the decoction after cooling.
Regular exercise also plays an important role in lowering LDL cholesterol and in raising the level of protective HDL. It also promotes circulation and helps maintain the blood flow to every part of the body. Jogging or brisk walking, swimming, bicycling and playing badminton are excellent forms of exercise.
Yogasnas are highly beneficial as they help increase perspiratory activity and stimulate sebaceous glands to effectively secrete accumulated or excess cholesterol from the muscular tissue. Asanas like ardhamatsyaendrasana, shalabhasana, padmasanaand vajrasana are useful in lowering blood cholesterol by increasing systemic activity.
Hydrotherapy can be successfully employed in reducing excess cholesterol. Cold hip baths for 10 minutes taken twice every day have proved beneficial. Steam baths are also helpful except in patients suffering from hypertension and other circulatory disorders. Mud packs, applied over the abdomen improve digestion and assimilation. They improve the functioning of the liver and other digestive organs and activate kidneys and the intestines to promote better excretion.
