In the fitness circle, I don't know if you have found such a strange phenomenon-that is, many fitness people only eat protein when eating eggs, and they are determined not to touch yellow. This is not forbidden, what is the reason? Let them throw the eggs yellow, they want to eat, they don't want to eat? Egg yolk vs protein First of all, many bodybuilders don't eat egg yolk because it is known to be rich in cholesterol, which is usually regarded as the chief culprit of cardiovascular diseases. Usually, the cholesterol content in egg yolk is about 185 mg, accounting for 62% of human daily intake. In other words, ordinary people only need to eat two whole eggs, and their cholesterol intake will greatly exceed one day.

On the contrary, protein wrapped in egg yolk has no cholesterol at all. For people with high demand in protein, they want to supplement enough protein with eggs, but don't want to take cholesterol. They can only give up egg yolk and eat protein. Come to think of it, everyone feels good, don't they? Excessive cholesterol intake = rising human cholesterol level? But the problem is that everyone's understanding of cholesterol is really comprehensive. What is this? First of all, cholesterol exists in lipoprotein particles in human blood vessels. Lipoprotein is divided into two types: one is low density lipoprotein. This is what we usually think of as "harmful cholesterol" that causes blood vessels and cholesterol that causes cardiovascular diseases; The other is high-density lipoprotein, which can help us clean up vascular density lipoprotein and transport it back to the liver. Cholesterol is also called "good cholesterol".

In fact, if you eat egg yolk, it will increase low-density lipoprotein and have high-density lipoprotein levels. The cholesterol level in whole blood is actually balanced. 199 1 year, there is an experiment. It is well verified for the above-mentioned 88-year-old male, and there are 25 complete eggs every day. After a period of time, his cholesterol level did not rise and he was healthy. Therefore, we can clearly understand here that although egg yolk is rich in cholesterol, it does not mean that the human cholesterol level will rise. Nutritional components of egg yolk In fact, egg yolk should not only be regarded as harmful to the "enemy" of most people. On the contrary, it is not helpful to supplement nutrition and strengthen muscles! Egg yolk is rich in calcium, iron, phosphorus, zinc, copper, manganese and thione, and also contains calcium pantothenate, B6, B9, B 12, vitamins A, E, D and K, and exogenous amines, fatty acids and choline. These nutrients are either lacking or the egg protein content is low.

In addition, we want to tell those who refuse to eat egg yolk that egg yolk is one of the main branched amino acids, which helps to promote muscle growth! People who work with egg yolk should be careful. There is no doubt that for most friends, in no particular order, egg yolk should be bold to eat, which is very good for your health. However, for the following three people, they are more cautious about egg yolk. It is necessary to control the total cholesterol intake-that is, this is a child who already has coronary heart disease, type 2 diabetes or eating habits. Therefore, after reading today's article, I believe that most of my friends should throw the egg yolk into the trash can!
