FIRE-Diet Study

This research study is examining whether diet can help reduce the effects of woodsmoke exposure on lung health. Woodsmoke is a common form of air pollution and can trigger inflammation in the airways, even in people without existing lung disease.

Participants will be enrolled as healthy volunteers and then assigned to either follow a diet rich in omega-3 or to continue their usual diet for a defined study period. The study team will provide support through meal or grocery delivery and regular check-ins with a registered dietitian to help participants follow the assigned diet.

Throughout the study, participants will attend research visits where lung function testing will be performed and biological samples (such as blood, urine, and sputum) will be collected. Participants will also take part in carefully controlled and closely monitored exposures to filtered air and woodsmoke, allowing researchers to compare lung responses under different conditions. Between visits, participants will complete brief at-home breathing tests and online questionnaires.

The goal of this study is to better understand whether specific dietary patterns can reduce airway inflammation and improve the body’s response to air pollution exposure.
