Researchers examined data from 8,000 children and their mothers to see how a mom’s diet during pregnancy affected food allergies in their children. They initially spoke to pregnant women in the 1990’s about their diets then followed up in 2009 to ask about the allergy status of the child.
The researchers, surprisingly, found that if a woman ate a serving of nuts, both peanuts and tree nuts, at least five times a week while she was pregnant, they were 69% less likely to report her child had nut allergies than the pregnant moms who ate nuts just once a month.
Even with these results, the researchers said women should err on the side of conservatism and not over do any one food, until there is more research done to confirm this association.
In the past, the American Academy of Pediatrics (AAP) has advised pregnant women to avoid peanuts, tree nuts, or other allergenic foods while pregnant, in order to protect their child against developing food allergies.
At this time, the AAP says there are no specific allergen-related foods pregnant women should avoid. But moderation and balance are key to good nutrition and health.
