It turns out that the main components of egg yolk are 17.5 per cent protein, 32.5 per cent fat, about 48.0 per cent water and 2 per cent minerals, as well as a variety of vitamins and other trace ingredients.

People think that the protein in eggs is concentrated in the protein. In fact, the protein content of egg white is only about 11%, but the water content accounts for 88%. The fat is also solidly concentrated in the yolk part, and the fat content of the egg white is only 0.2 percent. The fat in egg yolk is mainly monounsaturated fatty acids, more than half of which is oleic acid, the main component of olive oil, which is beneficial to prevent heart disease.

Egg yolk is rich in various vitamins

If you talk about vitamins, there is no doubt that most of them are concentrated in the egg yolk. Egg yolks contain valuable vitamins A and D, as well as vitamin E and vitamin K. These are "fat-soluble vitamins" and there is no trace of them in the egg white. Even the water-soluble vitamin B group, but also accounted for the vast majority of the presence in the egg yolk. In fact, part of the light yellow color in the egg yolk of the chicken farm comes from the color of riboflavin, which is vitamin B2, which can prevent common diseases such as mouth cracking, glossitis, lip pain and cracking.

Egg yolk is rich in various trace elements

All kinds of trace elements? Also concentrated in the egg yolk. There is a lot of phosphorus in the egg yolk, there is a lot of iron. Although the absorption rate of iron in egg yolk is relatively low, it still plays an important role for babies who cannot eat meat. At the same time, all the lecithin in eggs comes from the yolk, and lecithin can provide choline to help synthesize an important neurotransmitter-acetylcholine. Therefore, the baby's first food supplement is often egg yolk. Egg yolk is good for children's iron supplementation and is also good for children's brain development.

Egg yolk is eye protection

In addition to rich nutrients and healthy lecithin, egg yolks also contain unexpected healthy ingredients-lutein and zeaxanthin.

Lutein and zeaxanthin are both carotenoids, but they cannot be converted into vitamin A in the body. Nevertheless, they have a strong antioxidant effect, especially to protect the eyes. The imaging site of the human eye is the retina, and the retina has a "macula", the yellow inside, comes from lutein and zeaxanthin. These two types of substances help the eyes filter harmful ultraviolet rays, delay the aging of the eyes, prevent eye diseases such as retinal macular degeneration and cataracts, and are also good for the heart. Those dark yellow colored duck and chicken egg yolks are good sources of lutein and zeaxanthin. According to American research, more than 1/3 of the fat-soluble yellow substances in egg yolk come from these two components, and they are very easy to be absorbed by the human body, which is better than eating corn directly. Therefore, for normal eggs, the more yellow the yolk color, the better for eye health.

Can you eat red heart egg yolk

The color of the egg yolk is closely related to the feed of the chicken. If the feed contains more green leaves or yellow corn, the carotenoids contained in it will be absorbed into the egg yolk. So in general, free-range egg yolk color will be darker.

As early as 20 or 30 years ago, some people used this rule to add carotenoids to chicken feed, making the egg yolk bright and beautiful, which was loved by consumers. This practice is not harmful to health, or even beneficial. Nowadays, some people use the characteristics of egg yolk rich pigment and use toxic chemical dyes to enhance the color of egg yolk, which is really infuriating. But there is no need for consumers to stop eating because of choking and talk about egg yolk discoloration. dark yellow egg yolk, which is not contaminated by chemical dyes, is still a good food for health.

Main ingredients: pumpkin, salted duck eggs, coriander.

Seasoning: chicken essence, edible oil, salt.

Practice: Peel the pumpkin first. The pumpkin is then cut, seeded and cut into evenly sized strips. Remove the shell of salted duck eggs, take out the yolk, and crush the yolk with a knife (about 3-4 large duck eggs are needed for pumpkins weighing more than half a kilo). It is better to buy duck eggs produced by regular producers in supermarkets. Such salted egg yolks have more oil. Boil the water and blanch the pumpkin for not too long, then remove it for later use. Put the oil in the pan and fry the crushed duck egg yolk in the pan. Pay attention to the small fire! Stir-fry until bubbles rise, add a little water, the purpose is to dry the egg yolk, dilute it, do not put more. The egg yolk is already salty. Add a little salt and chicken essence. Pour the pumpkin blanched in advance into the pan and stir-fry evenly until the egg yolk is all over the pumpkin.
