A new study published in the Journal of Allergy and Clinical Immunology suggests that infants aged 3-15 months who are already allergic to milk or eggs may be at an increased risk of a peanut allergy if their mothers ingested peanuts while pregnant.
The study included 503 infants from the United States. Of those 503, 140 had a strong sensitivity to peanuts based on blood tests. Peanut consumption during pregnancy was a significant predictor of this test result.
This study comes on the heels of a recent retraction in the United States regarding when parents should introduce peanuts into their child’s diet. Experts now recommend waiting to introduce peanuts in a young child’s diet only if there is a history of food allergy within the family as there is no clear evidence that early peanut introduction causes allergies or that delaying peanut introduction prevents allergies.
