Medical studies examine food allergy risks and prevention

Recent medical findings highlight complexities in food sensitivities and the effectiveness of dietary interventions during pregnancy. The PrEggNut study, published in the New England Journal of Medicine, involved 2,137 pregnant women to determine if high consumption of eggs and peanuts could protect infants from developing allergies. The results showed no significant protective effect; 7.8% of children in the high-consumption group developed IgE-mediated allergies compared to 8.4% in the standard-consumption group.

Separately, experts are noting a rise in reported food sensitivities. While true food allergies affect approximately 4% of the German population, roughly 21% of adults experience an allergy or intolerance. A specific condition known as oral allergy syndrome affects about 70% of tree pollen allergy sufferers, causing reactions to raw fruits or vegetables due to heat-sensitive proteins, though cooked versions are typically tolerated.
