What do I need to know about eggs?
1, boiled eggs are best
According to the protein absorption rate in eggs, boiled eggs have the highest absorption rate, close to 98%, in addition to boiled eggs, you can also choose steamed egg soup, poached eggs. By cooking by high temperature methods such as stir-frying or frying, the protein absorption rate is reduced, and the protein in the egg is oxidized, increasing the burden on the gastrointestinal tract.
2, eat one egg a day
For adults, eating an egg in the morning will do. Vegans, growing and developing children or adolescents, pregnant women, etc. can eat 1 to 2 eggs. If you have cholecystitis or hypercholesterolemia, you should eat less egg yolks.
3. Control the time of boiling eggs
Eggs boiled for too long, the surface of the yolk is black, the reason for this phenomenon is because the cysteine in the protein is overheated, producing a large amount of hydrogen sulfide, hydrogen sulfide and iron in the yolk react with each other, resulting in iron sulfide. In addition, eggs boiled for too long can cause nutrient loss and oxidation of fat. Master the correct way to boil eggs, put the eggs in cold water, boil the water for 3 minutes, turn off the heat and continue simmering for 5 minutes.
4. Hard-boiled eggs should not be cooled with cold water

5, can not eat loose heart eggs
Many elderly people prefer to wash their eggs, although they are tender and have a good taste. However, the eggs are not thoroughly cooked and are susceptible to salmonella infection, which can cause abdominal pain and diarrhea. The eggs must be cooked thoroughly to maximize the killing of microorganisms and pathogenic bacteria.
6. Choose tea eggs carefully
Compared to boiled eggs, tea eggs do taste good, which is made from tea leaves, soy sauce and table salt. However, tea contains tannic acid and eggs boiled for too long, tannic acid combined with protein, hindering its absorption and utilization, so that the nutritional value of eggs is greatly reduced. In addition, tea eggs contain too much salt and are not suitable for patients with chronic stomach diseases and high blood pressure.
7. Master the storage method of eggs
The egg is sealed and stored, making the surrounding environment high temperature and humid, destroying the outer protective film of the eggshell, shortening the storage life of the egg, and causing the egg to deteriorate. Keep the eggs at room temperature, up to 10 days; It can also be refrigerated in the refrigerator and can be stored for about 15 days.
Tips
