1. Milk: contains protein, which can combine with lead in the body to form soluble compounds, thus preventing the body from absorbing lead. I suggest you drink 1 ~ 2 cups of milk every day.

2. Shrimp skin: The calcium content in each 100g shrimp skin is as high as 2g. The latest research shows that increasing dietary calcium intake is not only beneficial to children's bone development, but also can reduce the absorption of lead in gastrointestinal tract and the accumulation of lead in bones, which can effectively reduce children's absorption of lead and reduce its toxicity. For children exposed to low concentrations of lead, increasing the intake of calcium in diet can effectively reduce the absorption of lead.

3. Kelp: Kelp has the function of detoxifying and discharging lead, which can promote the excretion of lead in the body.

4. Garlic: Some organic components in garlic can bind lead and have the effect of dissolving lead toxicity.

5. Vegetables: Vitamin C in vegetables such as rape, Chinese cabbage and bitter gourd combines with lead to form water-insoluble and nontoxic salts, which are excreted with feces. Generally speaking, the lead content of plant food is higher than that of animal food, and the lead content of rhizome is the highest.

6. Fruits: Pectin substances contained in kiwifruit, dates and oranges can precipitate lead in the intestines, thus reducing the absorption of lead by the human body.

7. Yogurt: It can stimulate intestinal peristalsis.
