When lead is high in children, you can supplement foods rich in calcium, iron and vitamin C. Foods rich in calcium are dairy products and soy products, while foods rich in zinc and iron are animal liver, blood, meat, eggs and seafood, etc. You can also supplement fresh vegetables and fruits, and you can supplement rich vitamin C, all of which can avoid excessive absorption of lead. It is necessary to eat regularly on weekdays and avoid excessive consumption of greasy food and junk food, because the absorption of lead in the intestine will be increased when you are often in fasting state and consume excessively greasy food. In addition, it is important to develop good hygiene habits and not to take children to places with high lead content such as parking lots.
