Plant-based diets help prevent and treat asthma, according to a review published in Nutrition in Clinical Care. Researchers from the Physicians Committee examined the evidence related to asthma and dietary factors among adults and children. The prevalence of asthma rose over the years as high-fat, Westernized diets increased in popularity. Diets that emphasize fruits, vegetables, grains, and legumes and minimize saturated fat reduce the risk for asthma and may improve asthma control. The authors note the positive effects from consuming plant-based diets rich in antioxidants and fiber on factors including inflammation, oxidation, and gut microbiota as possible mechanisms. Dairy consumption was found to increase the risk for asthma and to worsen symptoms in asthma patients. Additional dietary interventions would further highlight the role of nutrition in prevention and treatment.
