Exclusively breastfeeding infants linked to higher allergy rates in young children, study finds

A new study from the University of Toyama, Japan, utilizing data from over 88,000 mother-child pairs in the Japan Environment and Children's Study (JECS), has investigated the correlation between infant feeding methods and childhood allergies. While confirming some benefits of exclusive breastfeeding (EBF), such as a 37% lower risk of asthma in the first year and reduced risk of allergic rhinoconjunctivitis, the research also found a significant link to increased food allergies. Exclusively breastfed children had an 82% higher risk of food allergies in the first year, 62% at age two, and 54% at age three, with male children showing a higher increased risk. The study suggests that the age of food introduction may be a factor, noting that early exposure to allergens between four and six months, as seen with peanut consumption in Israel, may help prevent allergies.
