The protein of eggs is concentrated in the egg white and egg membrane.
Other nutrients are concentrated in egg yolk, which is rich in fat-soluble vitamins, monounsaturated fatty acids, phosphorus, iron and other trace elements. Egg yolk is also a part of nutrients in eggs. The main minerals, vitamins and phospholipids in eggs are all in egg yolk. The main components of egg yolk are 17.5% protein, 32.5% fat, about 48% water, 2% minerals and multivitamins.
Deep yellow yolk is the source of lutein and zeaxanthin. More than 1/3 of the fat-soluble yellow substances in egg yolk come from these two components, which are easily absorbed by the human body. Therefore, for normal eggs, the yellow yolk is better for eye health, although people with coronary heart disease, hypertension, hyperlipidemia, high cholesterol and other diseases should not eat more eggs. However, a reasonable diet is no big deal. Experts suggest eating more fruits and vegetables while eating eggs, which can avoid high cholesterol and protect eyes.
