Published in August 2012 on the Environmental Health Services website, a study of adults with asthma and chronic obstructive pulmonary disease (COPD) found that “those with lower levels of certain antioxidants in their blood were more vulnerable to the harmful effects of air pollution.

This study is important because it indicates that a healthy diet including fruits and vegetables may protect against the common health threat of air pollution.”  To read an article about the study, click here.
