A recent Ministry of Health and Welfare report, which revealed that Japanese women's breast milkis tainted by dioxins--environmental estrogens that disrupt hormonal functions--is causing concern among young mothers. Although the ministry is trying to dispel their concern, experts are divided on the safety of breast milk. Some researchers warn that mothers might have to stop breast-feeding three months after givingbirth in order to reduce the intake of dioxins. On the other hand, doctors who recommend breast-feeding maintain that breast milk is crucial to the physical and emotional health of the mother and child.
