A new study published in Allergy, Asthma, and Clinical Immunology assessed maternal diet during the year before pregnancy and the last 3 months of pregnancy and investigated their associations with the risks of asthma, wheezing, allergic rhinitis and atopic dermatitis in young children. This study recruited 1140 mother-child pairs from the EDEN cohort. Mothers completed the food frequency questionnaires used to assess diet before and during pregnancy. Children were followed up using health questionnaires. The health outcomes studied were asthma, wheezing, allergic rhinitis and atopic dermatitis by the age of 3 years. The results revealed significant inverse associations between cooked green vegetable consumption before pregnancy and childhood asthma and consumption of eggs and raw vegetables before and during pregnancy, consumption of grains before pregnancy, and consumption of cooked green vegetables during pregnancy and allergic rhinitis. Additionally, for the first time, a notable positive association was found between meat intake during the preconceptional period and the risk of wheezing, allergic rhinitis and atopic dermatitis. The findings suggested that preconceptional and prenatal maternal intake of certain type of food groups may be preventive against asthma, wheezing and allergic rhinitis, whereas higher maternal intake of meat before pregnancy may increase the risk of wheezing, allergic rhinitis and atopic dermatitis in young children.
