New York, Nov 23: 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 breasmilk and breastfeeding.

The food protein-antibody complexes are then introduced to the offspring’s developing immune system, triggering the production of protective T immune cells that suppress allergic reactions to the food.

These protective cells also persist after antibodies from the mother are gone, promoting long-term tolerance to the food.

The findings support the recent allergy prevention guidelines, which reject prior advice urging mothers to avoid high allergic foods during pregnancy or while breastfeeding breastmilk.

“This controlled study shows that mothers should feel free to eat a healthy and diverse diet throughout pregnancy and while breastfeeding,” said James R. Baker, Professor at the University of Michigan.

“Eating a range of nutritious foods during pregnancy and breastfeeding will not promote food allergies in developing babies, and may protect them from food allergy,” Baker said.

The study, published in the Journal of Experimental Medicine, showed that breast milk from mothers who consumed allergenic foods protected against food allergy, preventing anaphylaxis as well as production of immunoglobulin E and expansion of mast cells, both hallmarks of an allergic response.

Breast milk was found protective even when fed to unrelated offspring not exposed to food allergens in utero.

In other experiments, mothers who had never consumed allergenic foods were given food-specific antibodies from other mothers. This, too, protected their breastfed offspring.

Human breast milk, fed to mice with humanised immune systems (tailored to respond to human antibodies), was also protective, suggesting that the mouse findings may translate to human infants. (IANS)

Thyroid dysfunction during the first half of pregnancy may indicate an increased risk for gestational diabetes — a form of diabetes that is typically diagnosed during the second trimester.

High thyroid hormone levels during pregnancy is also tied to increased the risk of premature delivery.

The researchers also warned that after birth, it may also cause the baby to develop conditions like hypoglycemia — low blood sugar — which can be dangerous if not treated correctly.

“Our study found that women with thyroid abnormalities in the first half of pregnancy are at an increased risk for gestational diabetes, a common pregnancy complication that can cause short and long-term health problems for women and their children,” said senior study author Cuilin Zhang of the National Institute of Child Health and Human Development in Rockville, part of the US National Institutes of Health.

In the study, published in the Journal of Clinical Endocrinology and Metabolism, the team examined medical records of 107 women with gestational diabetes and 214 other pregnant women.

“These findings, in combination with previous evidence of thyroid-related adverse pregnancy outcomes, support the benefits of thyroid screening among pregnant women in early to mid-pregnancy,” Zhang explained. (IANS)
