Is egg yolk good for health?

With the above nutritional value, egg yolk provides the body with most of the important nutrients. If you can get your hands on clean or omega-3 enriched eggs, they're even better. 

In 1961, the American Heart Association recommended that consumers limit the consumption of cholesterol in each meal, because this is believed to be the cause of cardiovascular diseases. A whole 100-gram egg (including the white and the yolk) can contain 422mg of cholesterol. Meanwhile, each person should only consume a maximum of 300mg of cholesterol / day. 

Therefore, eggs in general and the yolk - the main source of cholesterol in eggs in particular, are considered an unhealthy food according to medical recommendations in that period. 

However, according to recent studies, many health organizations have gradually abandoned the recommendations on limiting the amount of cholesterol each day to the body. According to the new interpretation, every day our liver produces cholesterol because it is an essential substance for the body. If you consume cholesterol-rich foods, your liver will produce less, and if you consume less cholesterol, your liver will have to work harder to produce it.

According to some studies, experts conclude that egg yolks should not be abused, eat a sufficient amount 

Besides, in every cell membrane of our body there is the presence of cholesterol. Therefore, eliminating or limiting the amount of cholesterol loaded into the body every day is no longer really necessary. 

In addition, cholesterol is not entirely bad because it is an essential substance involved in processes such as: 

• Vitamin D production .
• Production of hormonal hormones (testosterone, progesterone, estrogen).
• Produce bile acids that help break down fats.
