First of all, in the past, it was generally believed that an egg contained about 2 15mg of cholesterol, but the research results of USDA-ARS at 20 1 1 year showed that the present egg basically only contained about 185mg of cholesterol, which was not as high as before.

Second, the USDA removed the restriction on cholesterol intake in the dietary guidelines for American residents in 20 15 years. Recent research shows that cholesterol in blood mainly comes from human body's own synthesis and is influenced by many factors such as genes and hormone levels. Eating cholesterol from food will only have a slight effect on blood cholesterol content, and will not significantly increase the risk of cardiovascular disease.
Third, cholesterol exists in the form of lipoprotein in blood, among which low density lipoprotein cholesterol (LDL-C) will increase the risk of cardiovascular disease, while high density lipoprotein cholesterol (HDL-C) will reduce this risk. Eating cholesterol from food will increase the content of LDL-C to a certain extent, but it will also increase the content of HDL-C, thus maintaining a stable ratio between them, so it will not increase the risk of cardiovascular diseases.
Fourthly, egg yolk is rich in lecithin, which can not only protect cells from free radical attacks, but also delay cell aging to a certain extent, and is also an essential substance for brain development. In addition, lutein, vitamin D and other nutrients mostly exist in egg yolk, so it is a pity to throw them away directly.
At present, there is no conclusion on how many eggs should be eaten every day in academic circles, but most studies show that eating two eggs a day in healthy people will not lead to obvious risk of illness. Of course, people who have been ironing for a long time like you need a lot of protein, so it is safer to remove some egg yolks.
