Rich Sources
Lecithin is derived from the Greek Word, likithos, meaning egg yolk. Egg yolk is a rich source of lecithin, and also a rich source of cholesterol. This combination makes it possible for the lecithin to emulsify the cholesterol. Vegetable oils, whole grain cereals, soyabeans, liver and milk are other 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. Since these B vitamins are generally removed when grains are refined, people who eat exclusively white flour products are lacking them.

Benefits
The action of lecithin on the heart is the most important of all its proved benefits. It achieved its popularity initially in this area. Cholesterol is a fatty substance that tends to collect in the walls of the arteries and veins, thus narrowing them. This may eventually lead to a fatal blood clot. Scientific studies have shown that lecithin 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.
Like cholesterol, lecithin is continuously produced in the liver, passes into the intestine with bile and is absorbed in the blood. It helps in the transportation of fats. It also helps the cells to remove fats and cholesterol from the blood and to utilise them. It increases the production of bile acids made from cholesterol, thereby reducing the amount in the blood. It will thus be seen that cholesterol can cause trouble only if lecithin is lacking in the system.
All atheroscleroses or changs in the arterial walls are characterised by an increased of the blood cholesterol and a decrease in lecithin. It has been shown that experimental heart disease, produced by feeding cholesterol, could be prevented merely by giving a small quantity of lecithin. Atherosclerosis has been produced in various species of animals by increasing the blood cholesterol or decreasing the lecithin.
In normal health, when a diet high in fat is taken, there is tremendous increase in the production of lecithin. This helps in changing the fat in the blood from large particles to smaller and smaller ones. In case of atherosclerosis, however, the lecithin in the blood remains very low regardless of the quantity of fat entering the blood. The result is that, the fat particles remain too large to be able to pass through the arterial walls. A more serious situation can develop if there is lack of lecithin in cells also.
Besides reducing the cholesterol level in the blood, there is mounting scientific evidence to suggest several other benefits from lecithin. It has been suggested that its intake in sufficient amounts can help rebuild those cells and organs which need it. Lecithin helps to maintain their health once they are repaired. It may mean that a deficiency of lecithin in the diet may be one of the causes of ageing and that its use may be beneficial in retar- ding the ageing process.
Edward R. Hewith in his book, The Years Between 75 and 90 says, " with older people the fats remain high in the blood for from five to seven hours and in some cases as long as 20 hours, thus giving the fats more time to become located in the tissues. If lecithin is given to older people before a fatty meal, it has been found that the fats in the blood return to normal in a short time, in the same way they do in younger people."
In some cases, the cosmetic effect of lecithin does as much for the mental outlook of persons as it does for their physical well-being. It has been found to eliminate the yellow or yellow- brown plaques on the skin or around the eyes caused by fatty deposits. It is a natural tranquilliser which is beneficial in ner- vous exhaustion. It can produce great alertness in elderly people.
Some studies have indicated that lecithin increases the gamma globulin in the blood. This helps fight infection. It provides an increased immunity against pneumonia. It has also been found to lower blood pressure in some people. IN combination with vitamin E, it has proved helpful in lowering the requirements of insulin in diabetics. It has also proved valuable in the treatment of certain skin ailments, including acne, eczema and psoriasis.
Lecithin has been suggested as a sexual aid. It was used in Germany 30 years ago as a restorative of sexual powers, for glandular exhaustion and nervous and mental disorders. Seminal fluid is rich in lecithin. Because of its loss from the body, its need for men is regarded as specially great. Its use is also considered valuable in minimising pre-menstrual and menopausal tension.
Dr. N.A. Ferri, an eminent physician remarks - "Lecithin has a versatile function in life. It is an extremely important factor in the digestion and oxidation of fats, thus creating more muscle and glandular activity, resulting in greater body exertion and less fat accumulations. Lecithin is essential not only for tissue integrity of the nervous and glandular system in all living cells, but has been regarded as also the most effective generator and regenerator of great physical, mental and glandular activity. Shattered nerves, depleted brain power, waning activity of vital glands, find in lecithin, especially in the cellular structure of the nervous system and endocrine glands a source of dynamic energy."
The best way to increase lecithin is to eat the same amount of fat as usual, but reduce animal fat except that from fish. Oil may be used for cooking, seasoning and salad dressing. All hydrogenated fats such as margarines, cooking fats, hydrogenated peanut butter and processed cheese should be avoided as also foods prepared with them.
