The difference is not very big. Eating eggs is just egg white and yolk. Let's analyze the difference between egg yolk and egg white. Some people think that egg yolk is nutritious, and they only eat egg yolk instead of egg white. But some people are afraid of gaining weight, so they just eat egg whites and throw away egg yolks. Which is more nutritious, egg yolk or egg white? Professor Franz Chen, chairman of the China Nutrition Society, said that egg white and yolk have their own merits, but their nutritional components are very different. Except for 90% water in egg white, the remaining 10% is mainly protein.

Don't underestimate the 10% protein mainly contained in eggs. Professor Lin Xinying from the Institute of Nutrition and Food Hygiene of Shandong University also pointed out that egg protein is second only to breast milk and has a high utilization rate in human body. It is one of the highest quality foods in protein. I suggest that the elderly, children with low immunity and people who have just finished surgery should eat more egg whites to supplement protein. Eggs have colorful titles, such as "the most nutritious breakfast in the world", "the ideal nutrition bank" and "the best quality protein". But boiled eggs, steamed eggs, poached eggs, scrambled eggs and tea eggs. Different methods have great influence on its nutrient absorption.

This article lists and tells you which kind of eggs can best absorb protein, which is beneficial to the heart and supplements vitamins. Actually, it's boiled eggs How complex is the nutritional composition of egg yolk? Compared with egg white, the nutritional composition of egg yolk is much more complicated. 1) The fat in eggs is all concentrated in the yolk, but most of them are fatty acids that are beneficial to the human body. Oleic acid, the main component of olive oil, helps to prevent heart disease. 2) In addition, vitamins A, D, E, K, P, Fe and other minerals mainly exist in egg yolk. Although the absorption rate of iron is low, it is very important for babies who can't eat meat. 3) At the same time, there is a very important substance lecithin in egg yolk, which is particularly important for brain development and has the effect of lowering cholesterol. 4) The color of egg yolk is rich in nutrition code: riboflavin prevents the corners of the mouth from cracking, and lutein and zeaxanthin protect the eyes. 5) The deeper the yolk, the higher the vitamin content. Some people are afraid of cholesterol in egg yolk. "In fact, this is very wrong." .

Professor Franz Chen, chairman of China Nutrition Society, said that if the serum cholesterol of the elderly is too low, it will lead to low immunity and affect the strength of blood vessels, which is not conducive to cardiovascular and cerebrovascular health. Therefore, it is very healthy for healthy people to eat one or two egg yolks every day. For people with hyperlipidemia, it is more appropriate to eat half an egg yolk every day.
