In the daily diet, eggs are the most common nutritious foods, and they are often thought to have brain-enhancing effects, liver protection, arteriosclerosis prevention, cancer prevention, and aging. However, a 14-year study by Japanese scientists found that compared with their peers, women who eat 1 or more eggs per day have a lower mortality rate than women who eat only 1 or 2 eggs a week. To be higher. Japanese scholars have chosen 9300 men and women as subjects of study. These people had received a lifestyle survey in 1980, which included the different foods they regularly consumed.
The follow-up survey found that women who eat one egg each day have a 22% higher mortality rate than women who eat only one or two eggs a week (age, smoking habits, and weight are not counted) and eat two or more eggs each day. The mortality rate of women is higher, but the number of women in this area is small.
Women who eat the most eggs have a higher probability of dying from heart disease and stroke, although from a statistical point of view, the relationship between the two is not very tight. Scholars believe that this may also be related to the fact that women rarely die from these two diseases.
Nutrition experts believe that eggs should be boiled for 5-7 minutes. When fried eggs are too old, the edges will be scorched, and the high-molecular proteins contained in the egg white will become low-molecular amino acids. Such amino acids often form toxic chemicals at high temperatures.
Tips
Under normal circumstances, healthy adults eat 1-2 eggs a day; older people eat one better every day; mental workers eat two eggs a day is more appropriate; pregnant women, maternal, lactating women and frail people can eat every day 2- 3 eggs, not more. Cooking eggs is the best way to eat, but it's not advisable to overcook.
Nutrition experts advise: try not to eat egg yolk
To this end, the reporter interviewed relevant nutrition experts. Experts pointed out that eggs are high-protein foods. If they are eaten too much, they can lead to increased metabolites and also increase the burden on the kidneys. In general, healthy adults need only pay close attention to and control the intake through other means such as meat and dairy products.

In cooking, for adults, boiled eggs are the best way to eat, but they should not be overcooked. It is advisable to cook the eggs for 5-7 minutes in boiling water, but care should be taken to prevent absorption. Digestion; However, for children, steamed egg tarts and egg soup are the most suitable, because these two methods can make the protein loose and can be easily digested and absorbed by children. (In terms of nutrient absorption and digestibility, boiled eggs are 100%, scrambled eggs are 97%, tender fried is 98%, old fried is 81.1%, boiled water, milk boiled eggs are 92.5%, raw food is 30%~ 50%).
When fried eggs are too old, the edges will be scorched, and the high-molecular proteins contained in the egg white will become low-molecular amino acids. Such amino acids often form toxic chemicals at high temperatures. In addition, we must pay attention to tea eggs should be eaten less, because the tea contains acidified substances, combined with the iron elements in the eggs, stimulate the stomach, affecting the digestive function of the gastrointestinal.
Misunderstanding of eating eggs
Misunderstanding 1: The more women eat eggs, the better
Maternal labor in the delivery process of physical exertion, digestion and absorption function weakened, liver detoxification function decreased, a large number of food will lead to liver and kidney burden, causing adverse consequences. Ingestion of too much protein, but also in the intestine produce a large number of ammonia, hydroxyl, phenol and other chemical substances, a great poison to the human body, prone to abdominal swelling, dizziness, limb weakness, coma and other symptoms, resulting in "protein poisoning Syndrome." Protein intake should be calculated based on the body's ability to digest and absorb proteins. In general, maternal eating about 3 eggs a day is enough.
Myth two: eat high cholesterol cholesterol
No, because the egg yolk contains rich lecithin, it is a powerful emulsifier that can make cholesterol and fat particles become very fine, and can be fully utilized by cells through the blood vessel wall, thereby reducing cholesterol in the blood. And lecithin in the egg yolk can be released after the digestion of choline, into the blood and further synthesis of acetylcholine, is the main substance of neurotransmitters, can improve brain function and enhance memory.
Myth 3: raw eggs are more nutritious
Eating raw eggs is not only unhygienic, it can easily cause bacterial infections, and it is not nutritious. Raw eggs contain avidin, which affects the absorption of biotin in foods, leading to loss of appetite, general weakness, muscle pain, and other "biotin deficiency." In addition, raw eggs contain "anti-trypsin" that can destroy the body's digestive function. As for those “groomed eggs†that have hatched but have not hatched chickens, they are even less hygienic.
