Does wok cooking contain iron?

The impact of iron pots on human health is self-evident. A small amount of iron dissolved in traditional wok cooking is easily absorbed by human body, which can effectively prevent the occurrence of iron deficiency anemia and is very beneficial to human health.

However, rusty iron pots can't supplement iron, because the main component of rust is iron oxide, which is harmful to human body when ingested. The rust in the iron pot is iron oxide produced by the chemical reaction between iron atoms in the iron pot and oxygen atoms in the air. Experiments show that the main reason why the incidence of liver disease in urban people is higher than that in rural people is that they absorb too much iron oxide, and the most direct and harmful thing is the damage of iron oxide to human liver. Therefore, before cooking, you should wipe off the rust spots on the cooker.
