What harmful substances do preserved eggs contain?

Preserved eggs contain heavy metals such as lead, zinc and mercury.

Lead in preserved eggs is absorbed during children's growth and development, and will stay in tissues such as liver, lung, kidney, brain and red blood cells, leading to calcium loss in bones and teeth, causing adverse effects such as children's developmental retardation, anorexia and gastroenteritis, and even affecting intellectual development and nervous system. Once the damage is formed, it is irreversible.

Preserved eggs have a high sodium content, which is five times that of ordinary eggs, but the cholesterol content is no different from that of ordinary eggs. Patients with hypertension should eat as little as possible.
