Composite Dietary Antioxidant Index and Abdominal Aortic Calcification: A National Cross-Sectional Study (2024)

This study evaluates the association between the Composite Dietary Antioxidant Index (CDAI) and abdominal aortic calcification (AAC) among U.S. adults aged 40 and above. Using data from NHANES 2013–2014, the study found that higher CDAI levels correlated with reduced AAC scores, suggesting that a diet high in antioxidants may lower the risk of AAC, a predictor of cardiovascular disease. These findings highlight the potential of dietary antioxidants in preventing vascular calcification and underscore the need for further longitudinal studies.
