Abstract Summary The prevalence of allergic diseases has risen in recent decades, especially among children this increase in prevalence has become a serious public health issue. Although the etiology of this increase is not clear, it is likely due to a combination of genetic predisposition, environmental factors, and lifestyle changes, including dietary habits (Saadeh, et al., 2015).
