Manage your blood Cholesterol

Cholesterol can be both good and bad, so it's important to learn what cholesterol is, how it affects your health and how to manage your blood cholesterol levels. Understanding the facts about cholesterol will help you take better care of your heart and live a healthier life, reducing your risk for heart attack and stroke. To control your cholesterol, get a cholesterol screening, eat foods low in saturated fat and cholesterol, maintain a healthy weight, exercise regularly and follow all your healthcare professional's recommendations. Cholesterol is a fatty substance (lipid) found in animal tissue and fat. It is a Substance manufactured by the liver and other organs and consumed via animal fat. High-fat diets increase the amount made. It is believed that high levels lead to collection of cholesterol in the arteries, possibly leading to serious health risks. It is a soft, waxy substance. The body makes enough cholesterol to meet its needs. Cholesterol is used in the manufacture of hormones, bile acid, and vitamin D. It is present in all parts of the body, including the nervous system, muscle, skin, liver, intestines, and heart. Cholesterol is a peculiar molecule. However, the chemical term for a molecule such as cholesterol is alcohol, although it doesn't behave like alcohol. Its numerous carbon and hydrogen atoms are put together in an intricate three dimensional network, impossible to dissolve in water. All living creatures use this indissolvability cleverly, incorporating cholesterol into their cell walls to make cells waterproof. This means that cells of living creatures can regulate their internal environment undisturbed by changes in their surroundings, a mechanism vital for proper function. The fact that cells are waterproof is especially critical for the normal functioning of nerves and nerve cells. Thus, the highest concentration of cholesterol in the body is found in the brain and other parts of the nervous system. Because cholesterol is insoluble in water and thus also in blood, it is transported in our blood inside spheric particles composed of fats (lipids) and proteins, the so-called lipoproteins. Lipoproteins are easily dissolved in water because their outside is composed mainly of water-soluble proteins. The inside of the lipoproteins is composed of lipids, and here are room for water-insoluble molecules such as cholesterol. Like submarines, lipoproteins carry cholesterol from one place in the body to another. A high blood cholesterol is said to promote atherosclerosis and thus also coronary heart disease. But many studies have shown that people whose blood cholesterol is low become just as atherosclerotic as people whose cholesterol is high. Your body produces three to four times more cholesterol than you eat. The production of cholesterol increases when you eat little cholesterol and decreases when you eat much. This explains why the "prudent" diet cannot lower cholesterol more than on average a few per cent. There is no evidence that too much animal fat and cholesterol in the diet promotes atherosclerosis or heart attacks. For instance, more than twenty studies have shown that people who have had a heart attack haven't eaten more fat of any kind than other people, and degree of atherosclerosis at autopsy is unrelated with the diet. People with high cholesterol live the longest. This statement seems so incredible that it takes a long time to clear one
