The nutritional value and health benefit of eggs.
Nutritional Value of Eggs: 1. Eggs are rich in protein, fat, vitamins, iron, calcium, potassium and other minerals needed by the human body.
2. Rich in DHA, lecithin, and vitellogenin, which is beneficial to the development of the nervous system and body, can improve the brain and intelligence, improve memory and promote the regeneration of liver cells;
3. Eggs contain more vitamins B and other trace elements, which can decompose and oxidize carcinogenic substances in the human body, and have the effect of cancer prevention.
✵Health Benefits of Eggs: Benefit brain: egg yolk is rich in the lecithin, glycerin trifat, cholesterol, and yolk, has a great effect on the nervous system and physical development, can avoid the mental decline of the elderly and can improve the memory of all age groups.
Protect liver: the protein in egg has very good protection effect to liver damage. Lecithin in egg yolk is beneficial to the regeneration of liver cells, and can also increase the amount of plasma protein, enhance the metabolism and immune function of the body.
Prevention arteriosclerosis: nutritionist uses egg for prevention and cure arteriosclerosis, obtained unexpected and astonishing effect.
Prevent cancer: eggs contain more vitamins B2, can break down and oxidize human body carcinogenic substances. Trace elements in eggs, such as selenium and zinc, also have cancer-fighting properties.

The worst way to eat eggs.
✵1. Avoid undercooked eggs: Egg protein contains biotin protein, which will affect the absorption of biotin in food, causing the body to suffer from loss of appetite, general weakness, muscle pain, skin inflammation, eyebrow removal, and other symptoms. Eggs contain antitrypsin, which affects the body's digestion and absorption of egg protein. In uncooked eggs, these two substances are not broken down, thus affecting the digestion and absorption of protein.
Eggs carry bacteria in the formation process, in uncooked eggs bacteria, are not killed, easy to cause diarrhea. Therefore, eggs should be eaten after high-temperature cook, do not eat undercooked eggs.
The protein structure of raw eggs is dense, a large part of which cannot be absorbed by the human body. Only after cooking the protein becomes soft, can be digested and absorbed in the human gastrointestinal tract. Raw eggs have a special fishy smell, will cause central nervous suppression, so that saliva, gastric juice, and intestinal juice and other digestive juices secretion decreased, resulting in lack of appetite, indigestion.
✵2.Don't eat hard-boiled eggs: When an egg is boiled too long, the yolk forms a grey-green layer of ferrous sulfide on the surface, which is difficult for the body to absorb. Protein aging hardens and toughens, affects appetite, and is difficult to absorb.
✵3.Eggs should not be boiled with sugar: When eggs are cooked with sugar, they produce a substance called glycosyllysine, which destroys the beneficial amino acids in eggs. It also has a clotting effect and can cause harm when it enters the body. If you need to add sugar to a boiled egg, it should be left to cool and stirred.
✵4. Do not store hard-boiled eggs after dipping them in cold water: Some people often dip hard-boiled eggs in cold water to take advantage of the difference in the thermal expansion coefficient between the shell and the egg white, making the shell easier to peel off, but this practice is not sanitary. Because fresh eggs appearance with a layer of protective film, makes the moisture inside the egg less volatile, and prevent microbial invasion, eggshell membrane was damaged after cooked, egg chamber within some gas escape, will quickly within the eggs in cold water and temperature in a negative pressure cavity, cold water and microorganism will go into the egg from the holes on the membranes of the shell, storage easy to rotten.
✵
Eggs are not good for 4 kinds of people.
Contraindication: patient of high fever, diarrhea, hepatitis, nephritis, cholecystitis, coronary heart disease, better not take eggs.
✵1. Allergic to protein: Some people get stomach aches or spots after eating eggs, which are caused by egg allergies. Egg protein has antigenicity, with gastrointestinal mucosa surface with antibodies allergenic mast cells, can cause allergic reactions, appear with stomachache or abdominal pain, diarrhea, macula, and other allergic symptoms. Therefore, such people should not eat eggs.
✵2. Hypercholesterolemia: hypercholesterolemia person, especially severe patient, should eat few or do not eat as far as possible, or can adapt to eat albumen and do not eat the yolk, because the cholesterol content in the yolk is higher than albumen three times, can amount to 1400 milligrams per 100 grams.
✵3. Patients with kidney disease: those with kidney function and metabolism of nephritis decrease, urine quantity decreases, metabolites in the body cannot all be discharged by kidney outside the body, if eat egg too much, can make urea inside the body increase, bring about nephritis illness aggravation, even appear uremia. High blood pressure patients with advanced consumption of eggs will cause atherosclerosis in the kidney, systemic lupus erythematosus with kidney damage and a variety of chronic kidney diseases lead to chronic renal failure, should be careful to eat eggs or follow the doctor's advice.
✵4. Patients with high fever: the protein in an egg is a complete protein, enter the body can decompose to produce more heat, this calls food special dynamic effect. This special dynamic effect is the largest in protein effect, the effect of increasing heat up to about 30%. Therefore, after eating eggs in patients with fever, the body heat production increases, heat dissipation decreases, just like pouring oil on the fire, to reduce fever.
