Lecithin, triglyceride, cholesterol and vitellin in egg yolk play a great role in the development of nervous system and body. To keep a good memory, just eat one or two eggs a day.
The second is to protect the liver.
Protein in eggs can repair liver tissue damage.
The third is to prevent and treat arteriosclerosis.
The fourth is to prevent cancer.
Eggs contain 15% vitamin B2, which can decompose and oxidize carcinogens in human body.
The fifth is to delay aging.
Eggs contain almost all the nutrients the human body needs, so they are called "ideal nutrition bank". One of the longevity experiences of many elderly people is to eat an egg every day.
Eggs should also be eaten scientifically. For the elderly, it is better to cook, lie down, steam and toss eggs. Although frying, frying and frying are delicious, they are difficult to digest. If eggs are processed into salted eggs, their calcium content will increase obviously, from 55 mg per 100 grams to 5 12 mg, which is about 0/0 times of that of fresh eggs, and it is especially suitable for middle-aged and elderly people with osteoporosis.
In general, healthy adults eat 1-2 eggs a day; It is better for the elderly to eat one every day; It is more appropriate for mental workers to eat two eggs a day; Pregnant women, lying-in women, lactating women and the weak can eat 2-3 eggs a day, not more. Boiled eggs are the best way to eat, but they should not be overcooked.
Experts suggest how to eat eggs scientifically:
Take one every day and try not to eat egg yolk.
Scientists have found that although the cholesterol content of egg yolk is high, eating less eggs will not increase the cholesterol content in human body or the risk of heart disease.
They suggest that when eating eggs, it is best not to eat egg yolk as much as possible, because an egg yolk contains two-thirds of the cholesterol that healthy adults should consume every day. The American Heart Association suggests that healthy adults can eat an egg every day as long as they pay close attention to and control the amount of cholesterol ingested through other ways such as meat and dairy products.
Xiaobian support:
Teach you how to pick eggs-hold them in your hand, gently shake them so that they collide with each other and listen carefully; Or shake it in your hand and listen to its voice. Good fresh balls and eggs collide with each other with clear sound, and the eggs are shaken silently.
Boiled eggs: the most nutritious but not overcooked.
In cooking, for adults, boiled eggs are the best way to eat, but they should not be overcooked. It is advisable to cook eggs in boiling water for 5~7 minutes, but pay attention to chewing slowly, otherwise it will affect absorption and digestion; However, for children, steamed egg soup and egg drop soup are the most suitable, because these two methods can release protein and are easily digested and absorbed by children. (In terms of nutrient absorption and digestibility, boiled eggs are100%, scrambled eggs are 97%, tender fried eggs are 98%, old fried eggs are 81.1%,boiled eggs with boiled water and milk are 92.5%, and raw eggs are 30% ~ 50%).
When fried eggs are over-aged, the edges will be burnt, and the high molecular weight protein contained in egg white will become low molecular weight amino acids, which can often form toxic chemicals at high temperature. In addition, it should be noted that tea eggs should be eaten less, because tea contains acidified substances, which combine with iron in eggs to stimulate the stomach and affect the digestive function of gastrointestinal tract.
