What are the dangers of lead poisoning from preserved eggs?

Preserved eggs are a common food in our daily life, and many people like to eat them. They taste very good, but I believe everyone knows that the lead content in preserved eggs is very high. Some people who often eat preserved eggs in their daily life may not realize that they have been lead poisoned. Therefore, you must understand some of the dangers of lead poisoning so that you can effectively avoid it.

1. Short stature

One of the reasons why lead can affect physical growth is that lead can hinder the activation of vitamin D in the body, reducing its activity, and competitively inhibit the absorption of calcium in the gastrointestinal tract. The resulting metabolic disorder of vitamin D and calcium can affect the physical growth of children.

The second reason is that elevated blood lead levels can lead to lower thyroid hormone levels and reduced pituitary adrenal function, thereby affecting the function of pituitary growth hormone and slowing down the growth rate of children.

The third reason is that excess lead in the body accumulates in long bone tissue. The higher the blood lead concentration, the more serious the accumulation, which directly affects bone growth.

2. ADHD

When lead poisoning accumulates and deposits to a certain extent, it interferes with the normal metabolism of acetylcholine and catecholamines in the central nervous system, disrupting the excitation and inhibition processes of the cerebral cortex, which is then manifested through symptoms such as bad temper and hyperactivity.

3. Calcium, iron and zinc deficiency

Calcium, iron and zinc deficiency is the result of excessively high blood lead concentration. The oxidizing property of lead ions is stronger than that of calcium, iron and zinc, and they occupy the channels for the human body to absorb calcium, iron and zinc. Therefore, when supplementing calcium, iron and zinc, it is necessary to excrete lead and reduce the lead concentration first to be effective.

Only when the blood lead concentration drops will the concentrations of calcium, iron and zinc increase. As the saying goes, "If you take iron supplements without removing lead, it's like wasting money." The same goes for calcium and zinc supplements.

In short, although preserved eggs are delicious, you must not eat too much, especially for children. Lead poisoning will definitely have a great impact on the body. Therefore, you must pay attention to the moderation when eating preserved eggs. It is best not to feed preserved eggs to children, because the lead element in preserved eggs will accumulate in the body and cannot be excreted.
