What is cholesterol?
Cholesterol is a special kind of dense fatty alcohol contained in the cell membranes of organisms. The term is derived from the Greek words "χολή"( bile) and "στερεός"( solid).In nature it is mainly found in animal fats and offal.
Until the 19th century, cholesterol was called "fatty" or "cadaveric fat", since it is into this substance that the corpse( including muscles) almost completely turns into oxygen without access. Elevated levels of cholesterol in the body of a living person are associated with health risks.
Good and Bad Cholesterol
In a healthy body, approximately 80% of the cholesterol is synthesized by the body itself and no more than 20% is supplied with food( 1).Certain doses of this substance are necessary for the work of the nervous system, the production of a number of hormones( cortisol, testosterone, estrogen) and vitamin D.
Cholesterol is good( HDL, HDL is "
Cholesterol: normal level
The cholesterol level in the blood is measured either in mmol / l( millimole per liter, standard operating in the RF) or in mg / dl( milligram per deciliter, 1 mmol / L is 38.665 mg / dL).Ideal is the content of bad cholesterol in the blood below 100 mg / dL.
The cholesterol content within the range of 130-150 mg / dL is acceptable, above 160 mg / dL - requiring a diet, above 200-240 mg / dL - dangerous and requiring drug therapy, above 240 mg / dl - critical( 2).The ideal content of good cholesterol is 20% of the total.
Why does cholesterol go up?
Increased cholesterol levels in the blood can be caused by a diet with a significant proportion of animal products( fatty meat, butter, cheese), and metabolic problems and bad habits( smoking, excessive drinking).
Factors that indirectly affect the growth of bad cholesterol are persistent stress, lack of physical activity and obesity. In this case, high cholesterol, in fact, is more likely an indicator of the presence of any serious disorder in the body.
How to lower cholesterol?
Compliance with the diet can not only reduce cholesterol, but also gradually rid of its deposits on the inner walls of the vessels. The rules for such a diet are two: restricting the intake of cholesterol from food and helping the body to infer the old cholesterol.
Given that cholesterol is mainly found in animal fat, a significant restriction or total rejection of the following foods is recommended: egg yolk, fish caviar, butter, fatty meat( 3).Often doctors are recommended and the rejection of trans fats.
Cholesterol lowering products
The main product that reduces cholesterol is cellulose. Fiber is called a hard shell of plants, unable to digest by the human stomach. However, you do not need to spend money on the purchase of a pharmacy supplement - it is more useful to get fiber with food.
In addition to dietary fiber, natural vegetables contain many useful phytonutrients that can not be replaced by taking vitamins in tablets. The diet of a person trying to lower cholesterol should be based on the use of various vegetables.
How many cholesterol are in eggs?
In the yolk of one egg contains half the daily intake of cholesterol - 160-190 mg. A healthy organism can utilize this amount and only a minimal proportion of cholesterol will get into the blood, however, the disturbed metabolism will change the situation( 4).
If you rarely exercise, have even moderate excess weight, are a smoker and are constantly experiencing stress at work - do not be surprised if, as a result of the popular protein diet, you get cardiovascular disease.
Cholesterol, known as "cadaveric fat," is a dense fatty alcohol that can be deposited on the inner surface of the vessels, provoking their blockage. The main factors in increasing blood cholesterol are poor nutrition and bad habits.
