Why do eggs contain lead?

In the past, people used to add lead oxide in addition to salt, tea and alkaline substances such as quicklime and wood ash when making eggs. This causes lead in the eggs.

Frequent consumption of food containing excessive lead will cause lead to accumulate in the body, thereby jeopardizing the hematopoietic system, affecting the hematopoietic function of the bone marrow, and resulting in a decline in the body's immunity. At the same time, too much lead in the body will also cause damage to the nervous system, resulting in slow thinking, poor stability of the nervous system, and in some cases, nerve disorders.

. p>With the advancement of the process, the element of lead oxide used in the making of skin eggs has been replaced by zinc and salt, and the taste is not bad compared to the skin eggs made by the traditional process.

In fact, "lead-free eggs" are not really free of lead, but only after improving the process, the lead content is much lower than the original. Although the new process reduces the lead content in the eggs, but can not make it completely free of lead, so the real lead-free eggs do not exist. This shows that skin eggs should still not be consumed in excess.

Generally speaking, normal people try to avoid consuming eggs every day, and try not to eat more than one at a time; patients with high blood pressure, high cholesterol, liver and kidney disease, as well as children, pregnant women, the elderly and so on, should consume less or no eggs.
