Preserved eggs contain a certain amount of lead oxide, and excessive consumption will lead to lead accumulation in the body. Lead is a toxic metal, which will cause many systems of human body, such as nervous system, blood system, gastrointestinal system, cardiovascular system, kidney system and so on, 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 reduces memory and immunity, affects the absorption of minerals and vitamins, and leads to insufficient minerals such as calcium, iron and zinc in the body. Therefore, children should try not to eat preserved eggs often, which is not good for their health and will affect their future growth.
3, may lead to poisoning.
Preserved eggs are easily contaminated by bacteria, mainly salmonella, which may induce intestinal inflammation after entering the human body with preserved eggs, and produce strong toxins after fission, causing a series of poisoning symptoms, such as nausea, vomiting, headache, dizziness, abdominal pain, diarrhea and so on.

Preserved eggs are rich in cholesterol, which will thicken the blood vessel wall and is not suitable for patients 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 high blood pressure 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 within a certain range.
2. Pregnant women
Although the state 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 in order to make preserved eggs have good color and 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

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