Cholesterol (technically known as a sterol) is a substance found in animal fats and oils, nervous tissues, bile, blood and egg yolks. It has been found that people who suffer from diseases related to the arteries have a higher than average concentration of plasma cholesterol, and it has therefore been thought that an increased level of cholesterol in the blood have a higher risk of developing Atherosclerosis.
Recent studies have proved that by replacing any animal fats in the diet with vegetable oil containing polyunsaturated fatty acids, the plasma cholesterol falls and remains low as long as the animal fats are completely omitted from the diet.
It is interesting to understand and consider that mankind has been an omnivorous and an animal hunter for about two million years, during which time his diet was rich in animal fats as well as meat. In fact, the reasons behind the development of atherosclerosis remains unknown, although it is understandable that those who are in middle age to have a suspicion that they may have atherosclerosis to give up tobacco, take exercise and reduce their intake of fatty meats, butter, cream, salt and sugar.
There are a number of prescriptions available to help combat the level of cholesterol in the body.
To have cholesterol in the blood is an essential ingredient for the body to function, but too much of it can cause a malfunction. The steroids, including the sex hormones and the adrenal gland hormones are all made up of cholesterol; but only in limited quantities.
