Antioxidants in Diet Could Help You Breathe Easier as You Get Older
French researchers have found that dietary beta-carotene could help slow the natural decline in lung function with age. Comparing breathing tests in subjects eight years apart, the study discovered that those with the highest blood levels of beta-carotene—a dietary antioxidant—retained over 20% more lung function than those with the lowest beta-carotene levels. Over a 10-year span, researchers noted, the benefit of a specific increase in beta-carotene levels “approximately counteracts the effect of one year of aging.”
