protein allergies linked to antibiotic use

Ahead of the winter germs season, will you be demanding antibiotics for your children’s woes? A new study published in The Journal of Allergy and Clinical Immunology: In Practice reveals that antibiotic use is linked to the development of food allergies in children – including dairy, eggs, peanuts, and fish. The researchers matched 500,647 antibiotic non-users to 500,647 antibiotic users from 28 states across the United States, monitoring food allergy and the time developed. The results show that compared to antibiotic non-users, children with a history of using at least one antibiotic had a significantly increased risk of food allergy, and faster development of these allergies. The researchers believe that antibiotic use has a role in altering the microbiome through changes to the gastrointestinal microflora, and therefore could contribute to the increased risk of food allergies in those who have younger, less developed mucosal barriers.
