Lower Micronutrient Intake in Patients with Coronary Artery Disease: A Cross-Sectional Study

Background/Objectives: Coronary artery disease (CAD) is influenced by diet; however, the role of micronutrients remains underexplored. This study aimed to evaluate differences in dietary micronutrient intake between patients with and without CAD. Methods: A cross-sectional study was conducted with 107 participants (51 CAD, 56 non-CAD). Dietary intake was assessed using habitual 24-h dietary recalls and analyzed for micronutrient content. Biochemical, anthropometric, and clinical data were also evaluated. Results: CAD patients exhibited lower adequate intake of vitamins A, C, and K, as well as antioxidants such as lycopene and lutein, compared to the non-CAD group. While micronutrient inadequacy was prevalent in both groups, it was significantly more pronounced in subjects with CAD. Conclusions: Subjects with CAD had lower micronutrient intake than those without CAD, highlighting the potential importance of adequate micronutrient intake in the prevention and management of CAD.
