Yes, but not easily. There's a general process within the body of accumulation and removal of toxic substances. Dioxin is accumulated in fat which is hard to get rid of. If you lose weight, you lose some dioxin with the fat. If you're breastfeeding, you get rid of it through the breast milk. Infants get their greatest dose of dioxin during breastfeeding because it's concentrated in breast milk and because the infant is so small that the dose per pound of body weight is quite high. The benefits of breastfeeding still outweigh the risks of dioxin, though we'd rather not have to make such a choice.
