It is also rich in minerals such as calcium, phosphorus and iron; At the same time, it is rich in protein, and it is protein with higher price; And it is rich in vitamins, among which vitamin A, vitamin D and vitamin B are the most.

Nutritional components of egg yolk

Many people worry that egg yolk has a high cholesterol content, and eating it will increase the blood cholesterol content. Let's first look at the nutrients in the egg yolk to see if the egg yolk is nutritious or harmful.

The main components of egg yolk are 17.5% protein, 32.5% fat, about 48.0% water and 2% minerals, as well as trace components such as vitamins. People often think that protein in eggs is concentrated in protein. In fact, the protein content of egg white is only about 1 1%, but water accounts for as much as 88%. Fat is also concentrated in egg yolk, and the fat content of egg white is only 0.2%. The fat in egg yolk is mainly monounsaturated fatty acid, more than half of which is oleic acid, the main component of olive oil, which is beneficial to prevent heart disease. When it comes to vitamins, there is no doubt that most of them are concentrated in egg yolk.

Egg yolk contains 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 egg white at all. Even water-soluble B vitamins are mostly found in egg yolk. In fact, some yellow color in egg yolk comes from the color of riboflavin, which is vitamin B2, and can prevent common diseases, such as cleft mouth, glossitis and cleft lip pain. Various trace elements are also concentrated in egg yolk. Egg yolk contains a lot of phosphorus and iron. Although the iron absorption rate in egg yolk is relatively low, it still plays an important role for babies who can't eat meat. At the same time, all lecithin in eggs comes from yolk, which can provide choline and help synthesize an important neurotransmitter-acetylcholine. Therefore, the baby's first complementary food is often egg yolk. Egg yolk is good for children to supplement iron and is also good for children's brain development.

In addition to rich nutrition and healthy lecithin, egg yolk also contains unexpected healthy ingredients-lutein and zeaxanthin. Lutein and zeaxanthin are carotenoids, but they cannot be converted into vitamin A in human body. Even so, they have a strong antioxidant effect, especially to protect the eyes. The imaging part of the human eye is the retina, and there is a "yellow spot" on the retina, and the yellow inside comes from lutein and zeaxanthin. These two substances help the eyes to filter harmful ultraviolet rays, delay eye aging, prevent eye diseases such as macular degeneration and cataracts, and are also good for the heart.

Those deep yellow duck egg yolk and yolk are good sources of lutein and zeaxanthin. According to American research, more than one third of the fat-soluble yellow substances in egg yolk come from these two ingredients, and they are easily absorbed by the human body, which is better than eating corn directly. Therefore, for normal eggs, the yellower the yolk, the better for eye health.

Normal consumption of egg yolk will not lead to excessive cholesterol. This is because egg yolk is rich in lecithin. Lecithin is a powerful emulsifier, which can make cholesterol and fat particles extremely fine and pass through the blood vessel wall and be fully utilized by cells, thus reducing cholesterol in the blood. Moreover, lecithin in egg yolk can release choline after digestion, and then enter the blood to synthesize acetylcholine, which is the main substance of neurotransmitters, which can improve brain function and enhance memory.

In fact, everyone needs cholesterol. Only by taking too much cholesterol every day to form hypercholesterolemia will it harm your health. In fact, "moderate intake" is the key. Any nutrient, as long as you eat too much, will do you harm; Insufficient intake will also do harm to you. For the average person, eating 1-2 eggs a day is beneficial and harmless.

How to eat eggs to be nutritious?

In terms of nutrient absorption and digestibility, boiled eggs are 100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 8 1. 1%, boiled eggs with milk are 92.5%, and raw eggs are 30% ~ 50%. From this point of view, boiled eggs are the best way to eat, but pay attention to chewing slowly, otherwise it will affect absorption and digestion. But for children, steamed egg soup and egg drop soup are the most suitable, because these two methods can loosen protein and be easily digested and absorbed by children.

Nutrition of boiled eggs

First of all, boiled eggs are often half-cooked, and protein is not easily absorbed by the human body. Secondly, raw eggs contain avidin and antitrypsin. The former can affect the absorption and utilization of biotin by human body, while the latter can destroy the digestive function of pancreas. And these two substances are afraid of heat. After the eggs are cooked, these two substances will be destroyed and even have side effects. Besides. Because raw eggs contain various germs, it is easy to cause various diseases after eating.

It can be seen that it is totally undesirable to wash eggs with boiling water for nutrient absorption.
