Topic summary contributed by volunteer(s): Laura

Diets rich in carotenoids like beta-carotene may protect against radiation-induced DNA damage and oxidative stress in the lungs. Subjects suffering from asthma had lower circulating carotenoid levels; adding a few servings of fruits and vegetables to the diet reduced asthma exacerbation rate by half. Antioxidants like beta-carotene and vitamin C taken from diet could also help prevent bacterial vaginosis.
