A Breath Away with Antioxidants

0

Antioxidant-rich diets lower death rates for people with chronic obstructive pulmonary disease (COPD), according to a Centers for Disease Control and Prevention (CDC) study using data from the National Health and Nutrition Examination Survey (NHANES III). Concentrations of antioxidants in 1,492 people between the ages of 20- and 79-years-old who had obstructive lung function were compared to death rates during the subsequent 14-year period. Results showed that concentrations of lycopene and vitamin C were inversely associated with all-cause mortality. As levels of these two antioxidants increased, all-cause mortality rates dropped. Concentrations of lutein and zeaxanthin also were inversely linked with mortality, but only in smokers.
