Eating broccoli could help patients with chronic lung disease.
A decrease in lung concentrations of NRF2-dependent antioxidants, a key components of the lung's defense system against inflammatory injury, is linked to the severity of chronic obstructive pulmonary disease (COPD) in smokers. Broccoli is known to contain a compound that prevents the degradation of these antioxidants.
COPD is the fourth-leading cause of death in the U.S. It affects more than 16 million Americans.
