Egg Yolk Nutrition Facts

Many people consume yolks regularly – for example, for breakfast, in baked goods. An almost demonic glory haunts them. Some even argue that yolks contain such a proportion of cholesterol that can lead to the same effect as amphetamine. How justified such a reputation is, we will have to find out in this article.

Cholesterol that scares us

The egg itself is a low-fat product. However, at the end of the 20th century, a version appeared that the yolk is a source of harmful cholesterol, which in large quantities enters our body and is deposited on the walls of blood vessels, obstructing blood flow and causing atherosclerosis, which in most cases can lead to stroke. How much this corresponds to reality, no one can still say with one hundred percent accuracy.

But, say, in the United States, doctors cited facts that refute the harmful effects of yolks. As a result of research, they were able to establish that the increase in blood cholesterol levels with the regular use of eggs in food is not massive, it is manifested only in a certain group of people.

In fact, yolks significantly reduce the rate of accumulation of cholesterol in the body, which is due to the presence of lecithin in them. Our bodies actually need the cholesterol found in meat and eggs to produce testosterone, which helps build energy and muscle mass.

The benefits of egg yolk

The yolk contains many micro and macro elements, which include potassium, calcium, and phosphorus. Thanks to potassium, which is present in the yolks of chicken and quail eggs in the same quantity as in bananas, it is possible to avoid atherosclerosis and to put blood pressure in order. Calcium and phosphorus are also responsible for the health of bones, teeth, and hair.

The yolks contain many vitamins – A, B (almost the entire group), as well as D, PP, and E. Such a rich selection of vitamins, presented in the yolk, helps to improve the immune, nervous and cardiovascular systems. It also helps to activate metabolism, increase the body’s immunity and strengthen muscles.

As mentioned, yolks are rich in lecithin, which is an important structural element of cell membranes. Lecithin plays an important role in the formation and development of nerve cells.

Of course, it is worth observing the daily intake of cholesterol from food. It is equal to 300 mg. This corresponds to 1-2 yolks. However, don’t forget that cholesterol is also found in other foods.
