The Best Diet That Can Cure Asthma

Eating is an essential part of life. Beyond the concept of survival, it is well known that food plays an important role in preserving health. The famous Hippocrates's quote "let food be your medicine" introduced the idea of the potential impact of food on health. Nowadays, the role of food in chronic diseases, including cardiovascular disease, type 2 diabetes, metabolic syndrome, and cancer, is undisputed, and dietary interventions are an important component in managing numerous chronic diseases. The role of diet as a key factor influencing the development of allergic diseases has been described. The direct influence of food on asthma outcomes regardless of allergic status has emerged more recently, with dietary factors showing the potential to be directly involved in asthma pathogenesis. Obese asthmatics have a distinct phenotype with a unique pathophysiology (low eosinophilic inflammation, low allergen sensitization). The specific role of diet on asthma outcomes in obese patients is also of growing interest due to their limited responsiveness to inhaled corticosteroids, as well as other difficulties faced when managing these patients. The key question for clinicians is to know whether changes in the diet could benefit patients with asthma in routine practice. In this review, we will describe the impact of diet on asthma, and identify messages that can be used in asthma management. Given that obese asthmatic patients represent a particular group in terms of inflammation and clinical management, we will also focus on the effect of diet on asthma patients with obesity.
