Asthma is a chronic respiratory disease that impacts millions of people worldwide. Recent studies suggest that diet may play a role in asthma pathophysiology. Several dietary factors have been recognized as potential contributors to the development and severity of asthma for its inflammatory and oxidative effects. Some food groups such as fruits and vegetables, whole grains, and healthy fats appear to exert positive effects on asthma disease. On the other hand, a high consumption of dietary salt, saturated fats, and trans-fat seems to have the opposite effect. Nonetheless, as foods are not consumed separately, more research is warranted on the topic of dietary patterns. The mechanisms underlying these associations are not yet fully understood, but it is thought that diet can modulate both the immune system and inflammation, two key factors in asthma development and exacerbation. The purpose of this review is to examine how common food groups and dietary patterns are associated with asthma. In general, this research demonstrated that fruits and vegetables, fiber, healthy fats, and dietary patterns considered of high quality appear to be beneficial to asthma disease. Nonetheless, additional research is needed to better understand the interrelation between diet and asthma, and to determine the most effective dietary interventions for asthma prevention and management. Currently, there is no established dietary pattern for asthma management and prevention, and the nuances of certain food groups in relation to this disease require further investigation.
