Surely almost every adult person familiar with the term "cholesterol", which is an organic compound contained in the cells of every living organism.It is believed that elevated blood cholesterol is harmful and may lead to various diseases, particularly cardiovascular diseases.
Under cholesterol meant lipid substance, most of which is produced by the internal organs and sex glands.The rest of its share comes into contact with food.
value of cholesterol for the body:
- ensuring the stability of cell membranes;
- production of vitamin D;
- production of steroid hormones;
- effect on the nervous and immune systems;
- supply of tissues of the body with antioxidants.
Cholesterol - a substance necessary for life, are of particular importance for the metabolism of cells.Its role is also indispensable in the production of bile acids that help absorption of fats.Transport
cholesterol usually occurs in the form of complex compounds of lipoproteins as low density (LDL) and high (HDL).If
Effect of cholesterol on health
scientists found the influence of groups of lipoprotein on human health.In particular, high-density lipoprotein in a lot of positive impact on health.They are readily soluble, cholesterol does not precipitate, which contributes to protection from atherosclerotic vascular changes.The level of HDL in the blood is better than his figure is higher.
Low-density lipoproteins have poor solubility in the sediment is released cholesterol crystals, which is fraught with the formation of atherosclerotic plaques in blood vessels.Because of this there is an increase risk of complications of cardiovascular system, the occurrence of atherosclerosis and heart attack and stroke.Ideally, the level of low molecular weight lipoproteins should be not more than 100 mg / dl, and for cores - 70 mg / dl, which is extremely rare.When LDL level exceeding 160 mg / dL, shown diet reduces cholesterol.If the indicator above 190 mg / dL, it is recommended the appointment of drug therapy.
According to the data given in the medical literature, the rate of normal cholesterol level is 200 mg% or less, from 200 to 250 mg% - limit and a high level.When cholesterol levels over 250mg% doubles the risk of coronary heart disease.And for the index below 160mg% chance of developing cardiovascular events is reduced.
factors affecting increased cholesterol
The main reasons contributing to the increase of cholesterol levels in the blood are the following:
- low physical activity;
- stagnation of bile in the liver;
- food products with excess food items, leading to an increase in cholesterol in the blood;
- some endocrine disorders and diseases of the kidneys and liver.
measures to reduce the level of cholesterol in the blood
In order to reduce the level of cholesterol and prevent the formation of cholesterol plaques on the walls of blood vessels, first of all, should abandon the products saturated animal fats in food include foods rich in the fiber,vitamins, trace elements and contains easily digestible carbohydrates.In addition, you need to lead an active life, do not smoke and avoid alcohol.
