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)

High Sugar Levels In Mothers Can Risk Obesity In Child: Study

Lowering a mother's blood sugar during her pregnancy reduces the birth weight of the child.

Babies born to woman with higher blood sugar levels during pregnancy could be at significantly greater long-term risk of obesity – even more than a decade later, a study has found.

The higher the woman’s blood sugar, the greater the risk of her child being obese.

The researchers suspect that epigenetic changes are likely to be influencing these long-term outcomes and those changes begin quite early in pregnancy.

“The mother’s blood sugar level during pregnancy is an independent contributor to the child’s weight and risk of being obese later in childhood,” said Boyd Metzger, professor at the Northwestern University Feinberg School of Medicine.

In addition, mothers with higher-than-normal blood sugar during pregnancy — even if not at the level of gestational diabetes — also were significantly more likely to have developed Type-2 diabetes a decade after pregnancy than their counterparts without high blood sugar, the researchers said, in the paper published in the journal JAMA.

Lowering a mother’s blood sugar during her pregnancy reduces the birth weight of the child, as well as the risk of pre-eclampsia — potentially life-threatening condition in which the mother has high blood pressure that affects her and the baby.

If not regulated on time, these can potentially increase the number of women and children at risk of acquiring lifelong chronic medical conditions.

“The results are important because they demonstrate that even women with mild hyperglycemia during pregnancy and their offspring are at risk of harmful maternal and child health outcomes,” said coauthor Wendy Brickman, associate professor at Feinberg.

“Research is needed to identify interventions that will improve the health outcomes of these women and children,” Brickman said.

The study evaluated children 10 to 14 years after birth in 10 clinical centers in seven countries: the US, Canada, Israel, the UK, Hong Kong, Thailand and Barbados.

The study included 4,697 mothers and 4,832 children. (IANS)
