Everyday food may be a major hidden source of lead poisoning worldwide

Researchers estimate that the food people eat could account for roughly 40 to 50 percent of the lead in their bodies globally. Vegetables and grains carried the most, and children in poorer countries took in about three times more lead than children in richer ones.

Why it matters

Lead is a toxic metal that can damage the brain, especially in children, even in small amounts. This study suggests a large share of that harm may come from ordinary meals, because lead in soil and water gets taken up by food crops. It also warns that the legal limits for lead in food are old and may allow far more than health experts think is safe. Because these numbers come from a computer estimate rather than direct blood tests, they should be treated as a strong warning, not a final count.
