The prevalence of asthma and allergic diseases among children and adolescents has rapidly increased over the last 10 years, especially in the western world, and it has become a serious public health issue. Unfortunately, the reasons for this increase are still obscure but risk factors including genetic predisposition and environmental factors (change in lifestyle, air pollution, etc.) could be responsible. In fact, one hypothesis to explain the occurrence of asthma and allergies in childhood, are related to lifestyle factors. Among these factors, dietary habits may be one of the contributing factors (Saadeh, et al.,2013). |
