You can't eat preserved eggs during lactation. The content of heavy metals in preserved eggs is relatively high, and excessive lead will affect the absorption of calcium, leading to calcium deficiency in lying-in women. Lead may also enter the milk, leading to high blood lead in infants and affecting their growth and development. In addition, preserved eggs are raw and contain a lot of bacteria, which is easy to cause gastroenteritis. Therefore, it is not recommended to eat preserved eggs during lactation.

1. Preserved eggs will be added with lead oxide, copper sulfate and other ingredients during the curing process, which will lead to excessive heavy metals in preserved eggs, and excessive consumption will lead to lead poisoning. Lead in blood will also replace calcium, which will affect the absorption of calcium and easily lead to calcium deficiency.

2. The nutrition of breast milk during lactation is closely related to the mother's diet, and the lead in preserved eggs will also enter the milk, which will affect the baby's bone and tooth development after being ingested by the baby.

3. During lactation, in order to meet the baby's nutritional needs, the mother's immunity is in a relatively low state. Preserved eggs with bacteria exceeding the standard are easy to cause gastroenteritis.
