Risk of peanut allergy in pregnancy


Increased allergy risk from peanuts in pregnancy: pregnant women should avoid peanuts in favor of the child.

Eating peanuts during pregnancy significantly increases the risk of peanut allergy for the newborn. A study in the current issue of the "Journal of Allergy and Clinical Immunology" sees a direct connection between the consumption of peanuts and sensitization of the newborn. The experts therefore advise women to avoid eating peanuts during pregnancy.

Relationship between peanut consumption and allergy risk For some time now, some scientists and medical experts have assumed that peanut allergies develop during pregnancy. As early as 2000, the American Academy of Pediatrics (AAP) asked mothers with an increased family risk to refrain from eating peanuts during pregnancy. However, the actual causal relationship was always controversial in the professional world. A 2006 Cochrane analysis, for example, was unable to determine any evidence for the allergy-preventive effects of allergen avoidance in randomized clinical studies. In other words, the presumption of the direct connection between peanut consumption and allergy risk could not be confirmed. In 2008, the AAP also withdrew its recommendation to avoid peanuts for pregnant women. An observational study by the "Consortium of Food Allergy Research", which examines the topic in more detail, is currently in progress.

Peanut allergy risk tripled - Pregnant women should forego 503 infants were examined at the Jaffe Food Allergy Institute in New York as part of the study by Scott Safer now published in the Journal of Allergy and Clinical Immunology. The doctors found that there could be a connection between the consumption of peanuts during pregnancy and a later peanut allergy. The survey of the expectant mothers showed that the consumption of peanuts almost tripled the risk of sensitization in infants who were later breastfed (odds ratio 2.9; 95 percent confidence interval 1.7-4.9) and at The 71 children who were never breastfed even increased their risk of peanut allergy five-fold (odds ratio 4.99; 1.69-14.74). However, it should be taken into account that the information on peanut consumption was made by the pregnant women themselves, so that the exact amount consumed cannot be traced. Therefore, doubts remain about the suspected causal connection, so Scott Safer calls for additional randomized studies. However, since the allergen avoidance (no allergenic substances) has little effect on the diet with peanuts and no deficiency symptoms are to be expected due to the waiver, it is certainly not a mistake if women do not eat peanuts for the time being during pregnancy.
