Zhang Y, et al. - Via searches of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials from inception to October 30, 2018 to find relevant studies, researchers assessed the if there was a link between high adherence in pregnancy and childhood to the Mediterranean diet and the risk of childhood asthma and wheeze. This review included 18 observational studies. During pregnancy and childhood, high adherence to the Mediterranean diet may have short-term effects on early life wheeze in children. However, due to the heterogeneity of the studies, these findings should be interpreted with caution. Between high adherence to the Mediterranean diet in pregnancy and childhood and any of the other meta-analysis end points, including diagnosed asthma, there was no significant link.
