Question
A 4-year-old child is experiencing symptoms such as loss of appetite, hyperactivity, slow growth and development, constipation, feverishness, and excessive phlegm. Previous treatments have been ineffective. Seeking effective lead removal methods and preventive measures.
Answer
Treating high lead levels in a 4-year-old child should primarily focus on prevention and nutritional interventions. Firstly, implement health education, maintain a clean environment, wash hands frequently, and avoid consuming foods high in lead, such as dates and seafood. Consuming foods rich in iron, calcium, and zinc, like vegetables and carrots, can help in excreting lead. In the intestines, iron, calcium, and zinc compete with lead, enhancing the absorption of these nutrients and relatively reducing the absorption of lead.
