Preserved eggs contain a certain amount of lead oxide, and excessive consumption will lead to lead accumulation in the body. Lead is a kind of toxic metal, which will cause many systems of human body, such as nervous system, blood system, gastrointestinal system, cardiovascular system and renal system, and seriously endanger health. It is worth mentioning that the "lead-free preserved eggs" on the market are not "zero lead content", but the lead content is lower than the national standard, and frequent consumption may also lead to excessive lead.

2. Memory loss

In addition to the harm of lead, eating preserved eggs often will reduce memory, reduce immunity, affect the absorption of minerals and vitamins, and lead to insufficient minerals such as calcium, iron and zinc in the body. Therefore, children should try not to eat preserved eggs often, which is bad for their health and will affect their future growth.

3, may lead to poisoning.

Preserved eggs are easily contaminated by bacteria, mainly due to Salmonella, which may induce intestinal inflammation after entering the human body with preserved eggs, and it will produce strong toxins after fission, causing a series of poisoning symptoms, such as nausea, vomiting, headache, dizziness, abdominal pain and diarrhea.

Don't be greedy for these people, don't touch preserved eggs!

1, hypertensive patients

Preserved eggs are rich in cholesterol, which will thicken the blood vessel wall, and are not suitable for people with hypertension. In addition, some sodium food additives will be added in the process of making preserved eggs, which is not suitable for people with hypertension to eat in large quantities. Because hypertensive patients need to strictly control the sodium content in their daily diet, taking too much sodium will make it difficult to control their blood pressure in a certain range.

2. Pregnant women

Although the country suggests that food processing plants adopt the method of making "lead-free preserved eggs", in some small-scale factories, a certain amount of lead is still used for processing and production for preserved eggs with good color and good taste. Lead is not conducive to the growth and development of embryos, which will lead to the decline of embryo implantation rate and even lead to serious harm such as abortion of pregnant women and fetal malformation.

3. Children and the elderly

Children's body organs are still growing and developing, and the function of detoxification organs is weak, which has a certain impact on physical development such as teeth and intelligence. Preserved eggs are easy to produce heavy metals after pickling, and children are not easy to excrete toxins.

4. Patients with liver disease

The liver is the largest detoxified organ in the human body, and preserved eggs are preserved products. Many ingredients have certain side effects on the human body after eating, which requires detoxification of the liver, especially preserved eggs containing lead. Excessive consumption by patients with liver disease may cause lead poisoning.
