Abstract: Many studies show that the consumption of juices rich in polyphenols may increase serum antioxidant capacity, improve blood lipid profile, and endothelial function. The relation between the consumption of chokeberry juice and changes in the antioxidant capacity, blood lipid profile, and endothelial function as important indicators in the assessment of cardiovascular risk were determined. The study was conducted on a group of 11 healthy volunteers, who consumed chokeberry juice for three weeks. The research included determination of serum antioxidant capacity, blood lipid profile analysis, and measurements of endothelial function. The 3-week consumption of chokeberry juice significantly increased serum antioxidant capacity, and the best results were observed just after one week of the experiment. However, there was no significant change in the blood lipid profile, except for the persons with a higher level of triglycerides, in whom the consumption of chokeberry juice reduced these compounds to normal values. The endothelial function was normal in all patients and did not significantly change during the study.
