Abstract: Lung function gradually declines as adults age, which can make breathing more difficult. Previous studies have reported enhanced lung function among older adults with high intake of carotenoid-rich foods. The aim of this study is to investigate the association between carotenoid-rich diet and lung function. Data were taken from the Atherosclerosis Risk in Communities (ARIC) study, which included approximately 15,000 individuals aged 45-64 years at baseline from each of four counties in the United States. Food frequency questionnaire (FFQ) data were used to assess dietary intake of carotenoid-rich foods. Total carotenoids intake was calculated by adding five specific carotenoids – a-carotene, ß-carotene, ß-cryptoxanthin, lycopene, and lutein/zeaxanthin. Pulmonary function was evaluated as the ratio of forced expiratory volume in one second [FEV1] and forced vital capacity [FVC]. Linear regression analysis was used to assess the association between intake of carotenoids and pulmonary function. The association between the total carotenoid intake with pulmonary function was marginally positively significant. a-carotene, ß-carotene, and ß-cryptoxanthin intakes were individually significantly associated with a higher FEV1/FVC ratio in study participants. Dietary sources of pro-vitamin A carotenoids include yellow/orange fruits and vegetables such as oranges and sweet potatoes. Higher intake of these foods may improve pulmonary function.
