A new study suggests that eating nuts while pregnant may lower the risk of having a child with a nut allergy. The study authors think that pregnant women who consume nuts during pregnancy could have been helping their child build up an immunity to nut allergens. The study is the first to provide evidence that this is possible, CNN reports. The study authors controlled for factors such as a family history of nut allergies, and found the strongest link between eating nuts and babies who were resistant to nut allergies in women who ate five or more servings of tree nuts or peanuts per week.
The study utilized data from an ongoing Nurses’ Health Study II. Participants were children whose mothers had previously reported on their eating habits during pregnancy, United Press International explains. Out of the 8,205 children included in the study the scientists found that just over 300 had developed a nut allergy. One-hundred and forty of those cases were tree nut or peanut allergies.
