Excess lead in children means that the amount of lead in a child’s body exceeds the maximum limit of lead intake for children. The lead ingested by children does not accumulate mainly in the bones like adults, but enters the body tissues, so the lead overload is more harmful to children. Because the blood-brain barrier is not yet well developed in children, lead is more likely to cross the blood-brain barrier and cause permanent damage to brain development. The sources of lead in a child’s body include acquisition from the mother during pregnancy, or acquired intake (such as breathing polluted air, skin contact with toys containing excessive lead). After finding out that your child has an excessive lead level, parents should first carefully look for possible sources of lead exposure in your child’s living environment and take extra care. If the lead level is obvious, you can take lead detoxification drugs under the guidance of a doctor. Daily diet also needs to pay attention to eating less lead-containing foods (French fries, popcorn, skinned eggs, shellfish, poor quality canned foods, etc.), more shrimp, milk, soy products, carrots, garlic, beef, animal liver, etc. Supplementing nutrients and dietary fiber can effectively stop the absorption of lead in the body, which is the safest and most feasible way to treat mild to moderate lead poisoning at present.
