Back in 1815, a famous French chemistAt that time, Michel Chevrel synthesized a previously unknown substance, which he called cholesterol (literally translated as “hard bile”). The fact that cholesterol belongs to the class of alcohols was proved a little later by the physicist Marcelin Berthelot, because of which the substance found was renamed in several European countries, acquiring a more correct chemical name “cholesterol”. In the body of a healthy person, this substance performs many useful functions, among which you can see the formation of bile acids, vitamin D, and even sex hormones. However, excess cholesterol in human blood can lead to a number of serious chronic diseases. What is the reason for this property of cholesterol and is it possible to somehow regulate its presence in the body?
The benefits and harms of cholesterol
As mentioned above, cholesterol is reasonablequantity is essential for the normal functioning of the vital systems of the body. Most of this substance is produced by the liver, while about 20% of cholesterol is introduced into the body along with those foods that we most often eat. Excess cholesterol causes deposition of the substance at the walls of blood vessels, which has a very negative effect on the functioning of the human cardiovascular system and leads to all kinds of health problems.

Modern medicine knows that cholesterolcan be divided into several completely independent species. So, there is “beneficial” cholesterol, which consists of special high-density lipoproteins; "Bad" cholesterol, consisting of low density lipoproteins, as well as the so-called free cholesterol.
It is believed that it is bad cholesterol that causesthe creation of the same plaques inside the walls of blood vessels that we are so often told about from advertising any dietary supplement on television. It is deposits of harmful cholesterol in the blood vessels that interfere with the normal transport of nutrients inside the body, increasing the risk of coronary heart disease.

In addition to the possible development of cardiovasculardiseases, elevated cholesterol in the body can indicate many other diseases, among which liver diseases, pathologies of the endocrine system, diseases of the kidneys and pancreas stand out. However, low cholesterol also does not guarantee you a healthy face. It is known that low levels of beneficial cholesterol in the blood may indicate the possible presence of digestive problems, infectious infections, hypothyroidism, or even cirrhosis.
How to change blood cholesterol?
In order to reduce the content of lipoproteinslow density in the blood, it is most often recommended to follow a diet with the complete exception of fatty and refined foods. First of all, confectionery, sauces and mayonnaise should be abandoned, replacing them with healthier poultry, eggs and lean fish.
Despite the fact that low cholesterolis much less common than its elevated level, nutritionists recommend that their patients with a low content of this substance follow a diet that includes fatty fish, cheeses, nuts and other fat-rich foods.
