BACKGROUND: The aim of the study was to investigate the effects of sesame oil on endothelial function and to detect the underlying mechanisms, both in the postprandial state and after long-term consumption. DESIGN: We enrolled 30 hypertensive men in a two-phase study. In the first phase, 26 volunteers consumed 35 g of either sesame oil or control oil. Endothelial function, inflammatory activation and nitric oxide syntase (NOS) inhibition was assessed after a 12-hour fast and 2 hours after consumption of an oil-containing standardized meal. In the second phase, 30 volunteers consumed 35 g of sesame oil or control oil daily for 2 months and the above-mentioned parameters were assessed at baseline, 15, 30 and 60 days. METHODS: Endothelial function was estimated by endothelium-dependent FMD (flow-mediated dilatation) of the brachial artery. RESULTS: Flow-mediated dilatation (FMD) improved significantly both after acute (p = 0.001) and long-term sesame oil consumption (p = 0.015, p = 0.005 and p = 0.011 for 15, 30 and 60 days respectively). Intracellular adhesion molecule (ICAM) levels decreased significantly after only 60 days of daily sesame oil intake (p = 0.014). By contrast, no changes were observed in the control group in either phase of the study. CONCLUSIONS: This is the first study to show that sesame oil consumption exerts a beneficial effect on endothelial function and this effect is sustained with long-term daily use.
