Protein in the egg is in the egg white. It's okay to eat protein, but the cholesterol in egg yolk is high. Eating five or six egg yolks a day will definitely exceed the cholesterol level, so it is best to separate the egg white from the egg yolk when eating.
The main ingredient in beef is protein, which is very good for fitness, but it can't be overdone. In the final analysis, losing weight is to make the intake of calories greater than the consumption of calories.
Extended data:
Egg yolks mostly live in the center of protein and are hung at the poles by lacing. The volume of yolk accounts for about 30%~32% of the whole egg. The main component is vitellin, and the fat content is 28.
2%, fat mostly belongs to a kind of lecithin of phospholipids. From the point of human nutrition, egg yolk is rich in vitamin A and vitamin D, and contains high iron, phosphorus, sulfur, calcium and other minerals. There is a blastoderm in the yolk.
Egg yolk contains more cholesterol, which can be as high as 5 10 mg per 100 g. Therefore, many people, especially the elderly, are cautious about eating eggs, fearing that eating eggs will lead to increased cholesterol and atherosclerosis. Scientists have found that although eggs contain more cholesterol, they are also rich in lecithin. When lecithin enters the blood, it will make the particles of cholesterol and fat smaller and remain suspended, thus preventing the deposition of cholesterol and fat on the blood vessel wall.
Therefore, scientists believe that for the elderly with normal cholesterol, eating 2 eggs a day will increase the cholesterol in 100 ml of blood by up to 2 mg and will not cause arteriosclerosis. But you shouldn't eat too much. Eating too much is not conducive to gastrointestinal digestion, causing waste and increasing the burden on liver and kidney.
