OMEGA - Dietary Intervention - COPD Trial

Summary

A randomized controlled trial of a food delivery dietary intervention targeting increased omega-3 intake to determine whether dietary modifications can improve Chronic Obstructive Pulmonary Disease (COPD) outcomes and attenuate the adverse effects of particulate matter on respiratory health. Investigators believe that study results will comprehensively address the impact of an evidence-based nutrition intervention on COPD health and provide a framework for dietary intervention within other chronic diseases disproportionately impacting susceptible, low-income populations.
