According to analysis, every 100 grams of eggs contains 12.8 grams of protein, mainly ovalbumin and ovalbumin, which contain 8 essential amino acids for the human body and are very similar to the composition of human protein. The absorption rate of egg protein by the human body can be as high as 98%. . Each hundred grams of eggs contains 11 to 15 grams of fat, which is mainly concentrated in the yolk and is easily digested and absorbed by the human body.

2. Nutritional value of eggs

1. Brain-building and intelligence-enhancing

The lecithin, triglycerides, cholesterol and vitellin in egg yolk have a great effect on the nervous system and physical development. When lecithin is digested by the body, it releases choline, which can improve memory in all age groups.

2. Protect liver

The protein in eggs has a repairing effect on liver tissue damage. The lecithin in egg yolk can promote the regeneration of liver cells. It can also increase the amount of human plasma protein and enhance the body's metabolic and immune functions.

3. Prevent and treat arteriosclerosis

American nutritionists and medical workers use eggs to prevent and treat atherosclerosis, and have achieved unexpected and amazing results. They extract lecithin from eggs, walnuts, and pig liver, and give 4 to 6 tablespoons to cardiovascular patients every day. After 3 months, the patient's serum cholesterol dropped significantly and satisfactory results were achieved.

4.Prevent cancer

Eggs contain more vitamin B2, which can decompose and oxidize carcinogens in the human body. Trace elements in eggs, such as selenium and zinc, also have anti-cancer effects. According to an analysis of human cancer mortality worldwide, cancer mortality was found to be inversely proportional to selenium intake.

5. Delay aging

Eggs contain almost all the nutrients needed by the human body. One of the life-extending experiences of many long-lived people is to eat an egg every day. Many health-preserving medicinal diets spread among Chinese people are also inseparable from eggs. For example, Polygonum multiflorum boiled eggs, eggs boiled pig brains, egg porridge, etc. If eggs are processed into salted eggs, the calcium content will increase significantly, from 55 mg per 100 grams to 512 mg, which is about 10 times that of fresh eggs. It is especially suitable for people who want to supplement calcium.

Egg yolk contains a lot of cholesterol, which can be as high as 1510 mg per 100 grams. Therefore, many people, especially the elderly, are wary of eating eggs, fearing that eating eggs will increase cholesterol and lead to atherosclerosis. In recent years, scientists have found that although eggs contain more cholesterol, they are also rich in lecithin. After lecithin enters the blood, it will make the particles of cholesterol and fat smaller and keep them in a suspended state, thereby preventing the deposition of cholesterol and fat on the blood vessel walls. Therefore, scientists believe that if elderly people with normal cholesterol eat 2 eggs a day, the cholesterol in 100 ml of blood will increase by up to 2 mg, which will not cause arteriosclerosis. But you should not eat too much. Eating too much will not be good for gastrointestinal digestion, cause waste, and increase the burden on the liver and kidneys.

For example, after eggs are processed into salted eggs, their calcium content will increase significantly, from 55 mg per 100 grams to 512 mg, which is about 10 times that of fresh eggs. It is especially suitable for middle-aged and elderly people with osteoporosis.
