Arterial stiffness is not acutely modified by consumption of a caffeinated soft drink sweetened with high ‐fructose corn syrup in young healthy adults

This study investigated whether the ingestion of a caffeinated soft drink sweetened with high ‐fructose corn syrup acutely modified arterial stiffness. In a randomized counterbalanced, crossover design, fourteen young healthy adults consumed 500 ml of tap water or a caffeinated soft drink sweetened with high‐fructose corn syrup, after which carotid‐to‐femoral pulse wave velocity was measured. This study found that ingesting 500 ml of a commercially available caffeinated soft drink sweetened with high‐fructose corn syrup does not acutely change indices of arterial stiffness. AbstractWe tested the hypothesis that ingestion of a caffeinated soft drink sweetened with high ‐fructose corn syrup acutely increases arterial stiffness. In a randomized counterbalanced, crossover design, fourteen healthy adults (25 ± 3 years, 6 women) reported to the laboratory for two experimental visits where 500 ml of tap water (H2O) or 500  ml of Mountain Dew® (a caffeinated soft drink sweetened with high‐fructose corn syrup (HFCS)) were consumed. Arterial stiffness (carotid‐to‐femoral pulse wave velocity (cfPWV)), peripheral and central blood pressures were measured pre‐consumption, 30 min post‐consumption, and 120 min post‐consumption. Prior to each measurement period, beat‐to‐beat hemodynamic measures were collected. Changes in heart rate, blood pressure, and cardiac output from pre‐consumption did not differ between trials at any timepoint (p ≥ 0.06). ...
