Breastmilk of nursing mothers who eat foods that commonly cause allergy, such as milk, eggs, peanut, tree nuts, soy, wheat, fish and shellfish during pregnancy can help protect newborns from developing food allergies, suggests a new research. The mouse study, led by the University of Michigan, showed that when a nursing or pregnant mother is exposed to a food protein, it combines with her antibodies, which are transferred to the offspring through breastfeeding.
