There are six errors in eating eggs

According to experts, there are still many misunderstandings in the daily life of people who eat eggs.

Misunderstanding 1: Red shell eggs are better than white shell eggs

Many people only buy red shells when they buy eggs. They say that red shell eggs have high nutritional value. In fact, this is not the case. The color of the eggshell is mainly determined by a substance called "shell porphyrin," which has no nutritional value. Analysis shows that the nutritional value of eggs depends critically on the nutritional structure of the diet.

Misunderstanding 2: Boiling eggs is as old as possible

The egg is boiled for too long, and the ferrous ions in the egg yolk are combined with the sulfur ions in the protein to form insoluble ferrous sulfide that is difficult to absorb. 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.

Myth 3: Eggs have high nutritional value

Eggs are known as "fetal eggs." The nutrients (proteins, fats, sugars, etc.) contained in the eggs have been used by the embryos during the egg formation process, and the nutritional value is not high. Moreover, these eggs contain many E. coli, Staphylococcus, Salmonella typhi, Proteus and so on. Therefore, eating such eggs is not only unhelpful to the human body, but also causes food poisoning and other diseases.

Misunderstanding 4: Stinky eggs can still be eaten

In everyday life, people often have a special liking for rotten eggs.

Eggs are odorized because the eggs are left for a long time, or there are cracks. As the bactericidal substances in the egg white gradually decrease, the bacteria that invade through the pores or cracks in the egg shells multiply, producing methane, nitrogen, ammonia, carbon dioxide, and other substances, causing malodors. After the rotten eggs are cooked, amines, nitrites, and bacterial toxins are still present. After eating, they can cause symptoms such as nausea and vomiting. Eating too much can cause cancer.

Myth 5: "Functional Eggs" Are Better Than Regular Eggs

With the development of science and technology, various "functional eggs" rich in zinc, iodine, selenium, and calcium have come out. In fact, not all people are suitable for eating functional eggs. Because not everyone lacks the nutrients contained in functional eggs. Therefore, consumers should be targeted when selecting functional eggs and what they lack.

Misunderstanding 6: Elderly people avoid eating eggs

Because eggs contain high cholesterol, it has been popular to say that older people should not eat eggs. Scientific experiments in recent years have proven that this argument is not justified.
