Beetroot and beet greens are rich in nitrates, which have been shown to benefit lung function. Nitrates help relax blood vessels, reduce blood pressure, and optimize oxygen uptake.

Beetroot supplements have been shown to improve physical performance and lung function in people with lung conditions, including COPD and pulmonary hypertension, diseases that cause high blood pressure in the lungs.

Additionally, beet greens are packed with magnesium, potassium, vitamin C, and carotenoid antioxidants — all of which are essential to lung health.
