Eggs are a kind of high-protein food that people often eat, with high nutritional value, high absorption rate and low price, which is widely accepted by everyone. Because eggs are rich in high-quality proteins, lipids, fat-soluble vitamins, B vitamins and minerals, they are an important part of our balanced diet.

Eggs are relatively complete in various nutrients, but their cholesterol content is also high, so patients with coronary heart disease and high blood lipids should not eat too much.

Some people suggest that the cholesterol content of eggs is relatively high, and excessive intake of eggs will lead to an increase in serum cholesterol, which in turn will lead to cardiovascular diseases. In order to reduce serum cholesterol level, some people think that moderate egg intake will not have any effect on serum cholesterol level. Who should I listen to? Let's learn about cholesterol first.

what is cholesterol?

Cholesterol belongs to lipid, which is contained in all tissues of human body, and it is an important component of many biofilms. Cholesterol is the precursor of vitamin D3 and bile acid synthesis in the body. Cholesterol can also be converted into various hormones in the body, including cortisol, which affects the metabolism of protein, sugar and fat, aldosterone related to the metabolism of water and electrolyte in the body, and sex hormones testosterone and estradiol.

There are two main sources of cholesterol in the human body: one is endogenous, which is mainly synthesized by the liver, and the human body synthesizes 1-1.2 grams per day, which is the main source of cholesterol in the human body; the other is exogenous, and the cholesterol obtained from eating accounts for only 1/7-1/3 of the cholesterol synthesized in the body.

The cholesterol in eggs mainly exists in the yolk, but the egg white does not contain cholesterol. More than 95% of the cholesterol in the yolk exists in the form of ultra-low density lipoprotein (VLDL), accounting for about 2/3 of the dry matter of the yolk.

Many studies show that the blood cholesterol level has a greater relationship with factors such as fat intake and physical activity level, but has little relationship with the total cholesterol intake every day.
