Can I only eat four eggs a week?

The guidelines for healthy eating suggest that you should not eat more than three egg yolks a week and not consume more than 300 mg of cholesterol every day, except in protein. Eggs are rich in protein, but when the human body ingests too much protein, the kidneys can't excrete it. If it is deposited in the kidney for a long time, the blood circulation will be affected, which will not only affect the renal function, but also cause heart disease.

Duck egg: Chinese medicine believes that it tastes sweet and cool, and has the effect of clearing lung and nourishing yin. However, people with weak spleen and stomach, such as epigastric cold pain and cold food diarrhea, should not eat more. In addition, according to ancient medical books, duck eggs should not be eaten with turtles and plums.

Preserved egg: During the curing process, due to the infiltration of alkali solution into the egg, protein and fat decreased, and vitamins A, B 1 and B2 also decreased significantly. In addition, lead oxide is often used in processing, so a little lead will remain in eggshells and egg membranes. After eggshells and egg membranes are peeled off, they can be washed repeatedly with tap water for several times to reduce lead pollution. Garlic, vinegar and other condiments can be mixed when eating, which can reduce the absorption of lead by human body.

Quail eggs: people with cerebrovascular diseases should not eat more, because the cholesterol content in quail eggs is high, and the cholesterol content per 100 g is as high as 3.64 g. Excessive cholesterol intake is one of the main causes of arteriosclerosis.

Eggs are nutritious food, but for children, the more you eat, the better.

1 ~ 2-year-old children only need to eat 1 ~ 1.5 eggs a day, otherwise it will easily lead to indigestion and malnutrition. Adding sugar to eggs with boiling water can easily cause diarrhea and parasitic diseases. The correct way is: give children eggs, be sure to cook them, and eat steamed eggs as well. Some people also like to eat half-baked eggs. Protein of this kind of eggs (commonly known as preserved eggs) contains an alkaline protein, which can easily form an extremely unstable, inactive and unabsorbable compound with biotin. Eating half-baked eggs for a long time will lead to the lack of "biotin" in the human body.

There are also some people with weak constitution who eat a lot of eggs in order to increase nutrition and restore physical strength, which is also unscientific. The digestion and absorption function of people with weak constitution is correspondingly weakened, and the detoxification function of the liver is reduced. After eating a lot of eggs, the burden on the liver and kidneys will increase, resulting in adverse consequences. Excessive intake of protein will also produce a lot of ammonia, hydroxyl, phenol and other chemicals in the intestine, which is very toxic to human body, prone to abdominal distension, dizziness, limb weakness, coma and other symptoms, leading to "protein poisoning syndrome". Protein's intake should be calculated according to protein's digestion and absorption function.

Finally, I would like to remind you that scrambled eggs should not add monosodium glutamate. Eggs themselves contain a lot of glutamic acid and a certain amount of sodium chloride. If monosodium glutamate is added, these two substances will generate a new substance-sodium glutamate, the main component of sodium glutamate, and the umami taste of the egg itself will be covered up.
