This study hypothesized that the change in age-related dietary intake affects lung function. The subjects who undertook a dietary assessment and spirometry in 2012 and 2017, were retrospectively collected in a health screening center. Dietary intakes were directly evaluated using food frequency questionnaires (FFQ) administered by trained dietitians and were compared at the baseline (2012) and 5-year follow-up (2017). A forced expiratory volume in one second (FEV1)\/forced vital capacity (FVC) value below 0.70 was defined as airflow limitation. Logistic regression models were used to estimate the odds ratio (ORs) adjusted for potential confounders. A total of 1439 subjects with normal spirometry were enrolled. New airflow limitations were detected in 48 subjects (3.3%) at the 5-year follow-up, including 41 (85.4%) men and 11 (22.9%) current smokers. After adjusting for age, sex, smoking history, and baseline FEV1\/FVC, the odd ratios (OR) for new airflow limitation in fiber, vitamin C, and folic acid per 10% decrease in daily recommended requirement were 2.714 (95% confidence interval (CI), 1.538\u20134.807; p = 0.001), 1.083 (95% CI: 1.020\u20131.149; p = 0.007), and 1.495 (95% CI: 1.172\u20131.913; p = 0.001), respectively. A decreased intake of dietary fiber, vitamin C, and folic acid is associated with a newly developed airflow limitation.<\/jats:p>","DOI":"10.3390\/nu13020580","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T16:12:10Z","timestamp":1613146330000},"page":"580","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["The Impact of Changes in the Intake of Fiber and Antioxidants on the Development of Chronic Obstructive Pulmonary Disease"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7510-4531","authenticated-orcid":false,"given":"Young Ju","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Pulmonology and Critical Care Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul 05505, Korea"},{"name":"Health Screening and Promotion Center, Asan Medical Center, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7031-7009","authenticated-orcid":false,"given":"Se Hee","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pulmonology, Allergy and Critical Care Medicine, CHA Bundang Medical Center, CHA University, Seongnam 13496, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji Ho","family":"Chang","sequence":"additional","affiliation":[{"name":"Health Screening and Promotion Center, Asan Medical Center, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hye Seung","family":"Lee","sequence":"additional","affiliation":[{"name":"Health Screening and Promotion Center, Asan Medical Center, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun Hee","family":"Kang","sequence":"additional","affiliation":[{"name":"Health Screening and Promotion Center, Asan Medical Center, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4814-6730","authenticated-orcid":false,"given":"Sei Won","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pulmonology and Critical Care Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mathers, C.D., and Loncar, D.
