I knew I had something in writing at work so waited to anwer this. Anne Eglash MD from Wisconsin had an article int he ABM News, Vol. 4, no. 1, 1998 on this very topic. It is a case report which discusses this. There are no studies that support this theory but she states: "lectithin has been observed clinically to prevent the reoccurance of plugged ducts in breastfeeding women" a quote referenced to R. Lawrence 4th ed. Many other factors can cause plugged ducts such as oversupply, poor latch on, constrictive clothing, breast trauma or infections. Perhaps a nutritionist who understands the connection can help us out.
