High density lipoprotein cholesterol (HDL cholesterol) transports fats including total cholesterol from one cluster of cells to another where HDL cholesterol is preserved or disintegrated. HDL cholesterol transfers cholesterol from heart vessels, cardiac muscle, cerebral artery and other peripheral organs into the liver where the bile is formed from cholesterol. HDL cholesterol removes the excess of cholesterol from the cells.
The probability of the disease is reducing if the density of cholesterol is high and there is a lot of “good” cholesterol there in blood. “Good” cholesterol can capture “bad” one, forward it into the liver where “bad” cholesterol is utilized. Also, being the part of cell membranes, cholesterol is necessary for many essential processes like the process of cell division and organism regeneration processes. Cholesterol is necessary for growth and skeleton bones’ formation as it participates in synthesis of vitamin D which is aiding in fixation of calcium. Cholesterol is very important for fast-growing children.
The higher level of “good” lipoproteins the less probability of atherosclerosis. For example, “good” lipoproteins are increasing when we eat seafood, do sports. Such “fresh” idea as “Sport is health” can be revalued. Besides it was noted that some toxins contribute to the increase of high density lipoproteins. Alcohol is one of such toxins. Belgian scientists found out that people who consume grain alcohol in small doses have little risk of coronary disease and their level of “good” lipoproteins is higher compared with those people who don’t absolutely consume alcoholic drinks.
However, the effect disappears or becomes opposite if the dose is more than 50g of grain alcohol. More over, small dose of alcohol is harmful for people suffering from atherosclerosis and increased blood pressure.
For example, cholesterol is the peculiar material for producing all steroid hormones including sex hormones. In other words, sex hormones are altered cholesterols. Partially it is synthesized in the organism and partially it should come with the greasy food. As a result of this people who don’t consume cholesterol have problems with sexual drive. Sexual activity increases the level of “good” lipoproteins as well. This notion allowed introducing the rule of three “S” (sports, spiritus, sex) as preventive measures of cardiovascular diseases. Note that smoking leads to the reduction of high density lipoproteins.
Whatever non-cholesterol diet is and no matter how hard we try to replace “bad” cholesterol by “good” one, it’s impossible to be sure that we are absolutely protected from this disease. There is another factor causing such fatal disease except food. It’s so called immovable (passive) stress by which active stress of the primitive man was replaced. Now a man has no need to hunt. It’s difficult to change dramatically life style of a modern man. But it’s necessary to reconsider it: atherosclerosis of heart vessels is more frequent among brain workers than among manual workers. One hour of walk each day at an average pace is a good physical load for your body.
