Fish oil diet tested as COPD treatment in new study
NCT ID NCT05297279
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether eating more omega-3s (found in fish and certain oils) can improve breathing and daily life for people with COPD. Researchers will provide food to 200 adults with moderate-to-severe COPD and track their symptoms and flare-ups over time. The goal is to see if a simple diet change can help manage this chronic lung disease.
