How could diet affect COPD?

A diet high in antioxidant-rich fruit and vegetables has been associated with a lower risk of developing COPD, though it is unclear whether this diet will help to manage symptoms. COPD is associated with worsened outcomes in malnourished individuals, such as muscle wasting and reduced exercise capacity, which leads to worsened quality of life and increased mortality risk, so it is especially important to maintain a healthy diet in those with COPD.^[1]
