Asthma (and Dietary) Inflammation Reduction

The purpose of this study is to evaluate the effects of a diet that is low in glycemic load and abundant in fiber, fruits, vegetables, legumes and omega-3 fatty acids ("anti-inflammatory diet") on pulmonary function in pediatric patients with asthma. The primary endpoint will be change in forced expiratory volume in one second in response to the diet intervention. Secondary outcomes will include additional spirometry measures, fraction of exhaled nitric oxide, and assessment of symptomatic asthma control. In addition, we will identify potential physiological mechanisms relating diet with lung function, including changes in systemic inflammation, insulin sensitivity, and intestinal microbiome composition.
