Introduction: Pediatric asthma is the inflammatory condition with the highest burden of chronic disease in children. Awareness of the undesirable effects of modern lifestyles, including sedentary behavior and eating habits associated with Western diets, has led to novel approaches in clinical practice. Current concerns focus on the possibility of non-pharmacological intervention to achieve better disease control and normal lung function in these children. Method: In this narrative review, we analyzed current information on the influence of dietary patterns on lung function. The aim was to clarify the extent to which current knowledge provides arguments for applying certain dietary measures to asthma patients in order to optimize lung function. We conducted research in the literature to evaluate the impact of Western diet, Mediterranean diet, and micronutrients status on lung function. We also focused on how maternal diet during pregnancy can influence lung function in offspring. Results: We found a positive impact on lung function in children who adhere to the Mediterranean diet, in contrast to the Western diet which is related to low asthma control. Deficits of micronutrients like selenium, zinc, iron, and vitamin D are linked to impaired lung function. Maternal intake of fiber, vitamin A, vitamin E, zinc, and selenium during pregnancy is correlated with better FEV1 and FVC. However, current information on this topic is controversial, and there is no clear data on intervention measures in clinical practice. Conclusions: Evaluation and clear recommendations of diet could contribute to a better management of children with asthma.
