An egg is laid by a hen, with a hard shell outside and an air chamber inside, egg white and yolk. They are rich in cholesterol and nutrition, and are a good source of high-quality protein and B vitamins, and can also provide some fat, vitamin A and minerals. Has the effects of protecting liver, strengthening brain, improving intelligence and protecting eyesight.
1, protecting liver
Protein in eggs can repair liver tissue damage, and lecithin in egg yolk can promote liver cell regeneration, increase the amount of human plasma protein, and enhance human metabolic function and immune function.
2. Brain and intelligence
Egg yolk contains triglycerides, cholesterol and yolk protein, which plays a great role in the development of nervous system and body. Lecithin can release choline after being digested by human body, promote brain development, improve memory and prevent Alzheimer's disease.
3. Blood
Eggs are rich in iron, which plays the role of hematopoiesis and transporting oxygen and nutrients in blood, thus achieving the effect of enriching blood.
4. Protect your eyesight
Eggs are rich in lutein and zeaxanthin, which can protect eyes from ultraviolet rays. Eating eggs is also good for computer users who use their eyes too much.
Step 5 lose weight
Eggs are high in nutritional value and protein content, but relatively low in fat and carbohydrate content. Therefore, eating eggs properly will not only make you fat, but also supplement the nutrients needed by the human body.
nutritive value
Eggs are rich in protein, mainly ovalbumin and ovoglobulin, and also contain essential amino acids, which are very similar to the composition of human protein, and are beneficial to the absorption of protein in eggs.
The fat in eggs is mainly concentrated in the yolk, which is easily digested and absorbed by the human body. Egg yolk is rich in sterol, egg yolk, calcium, phosphorus, iron, vitamin A, vitamin D and B vitamins, which is of great benefit to improving the function of nervous system.
Egg yolk also contains 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.
Eggs are especially rich in methionine and contain other important trace elements, such as potassium, sodium and magnesium. Eggs are rich in phosphorus, but calcium is relatively insufficient, so milk and eggs are complementary in nutrition.
