β-Sitosterol has become a popular cholesterol-lowering functional food product worldwide. β-Sitosterol can be oxidized to β-sitosterol oxidation products (SOPs) during food processing. Little is known about the impact of SOPs and β-sitosterol on the functionality of arteries. This study investigated the effects of SOPs and β-sitosterol on vasorelaxation and the possible cellular mechanisms involved.
