The Association of Higher Composite Biomarker Score of Antioxidant Vitamins with Lower Cardiovascular Diseases Risk: A Cross-Sectional Study

Biomarkers for the dietary system, which includes a mixed fruit and vegetable (FV), are needed to understand the association of FV intake with a reduction in cardiovascular diseases risk. This is a cross-sectional study that aims to find the potential relationship between a high composite score comprised of antioxidant vitamins and a lower incidence of cardiovascular diseases (CVD). Atotal of 94 (42 males and 52 females) participants (mean age +/- SD: 51.7 +/- 9.4 years) completed a specific questionnaire including a quick food scan, which has designed by the American National Institutes of Health. The vitamins A, C and E were determined using high-performance liquid chromatography (HPLC). An enzymatic colorimetric method was used to determine other biomarkers [fasting blood sugar (FBS), haemoglobin A1c (HbA1c), and lipid profile]. A Composite Biomarker Score (CBS) comprising of the plasma vitamins (A, C, and E) have been derived. The results showed that male participants demonstrated significantly higheratherosclerotic cardiovascular disease (ASCVD) risk than female participants. Female participants with greater ASCVD risk were associated with significantly higher age, total cholesterol, and triglyceride concentrations. Additionally, there is a significant relationship between the CBS with lower ASCVD risk. Consequently, it can be concluded that higher concentrations of serum antioxidant vitamins are related toa reduction in cardiovascular diseases risk.
