Maternal influences on food allergy prevention: A closer look at diet and environment

By Pooja Toshniwal PahariaApr 9 2024Reviewed by Susha Cheriyedath, M.Sc. In a recent review published in the journal Nutrients , researchers explored the role of maternal factors in preventing food allergies.

International standards advise against exclusion diets due to the possible negative impact on vital dietary intake and general health. Although research on prenatal prebiotic and probiotic consumption is encouraging, there is minimal scientific evidence. Further research is needed to understand the combination of genetics, immune mechanisms, and environmental variables.

Environmental variables and allergen exposure generate several reactions, each having different allergic propensity effects. Amniotic fluid includes antigens exposed to the mother, which the fetus may swallow, potentially leading to Th2 cell sensitization in small intestinal cells. Maternal immunoglobulin E antibodies have high affinities for neonatal IgE receptors, increasing the likelihood of sensitization even at low antigenic concentrations.

There is no particular suggestion for prebiotics, probiotics, or symbiotics to help pregnant women avoid FAs. Existing recommendations acknowledge the influence of probiotics on eczema prevention; however, they do not recommend utilizing prebiotic or probiotic supplements to prevent FAs. The World Allergy Organization's recommendations do not yet include a particular recommendation for prebiotic supplementation during pregnancy or nursing.
