Popis: | Objectives Anthocyanins derived from different plant sources have been found to possess a variety of health-promoting effects, including antiinflammatory properties and protection from oxidative stress. The aim of this study was to investigate the dose-response relationship between anthocyanins and metabolic risk factors as well as inflammatory and oxidative biomarkers in healthy adult volunteers. Methods We conducted a randomized, double-blind, placebo-controlled trial, which included an increasing dosing schedule of 20, 40, 80, 160, and 320 mg of purified anthocyanins or placebo. Participants (n = 111) were administered either agent for 14 consecutive days. Results No significant differences in either baseline characteristics or daily intake of dietary nutrients were detected between the experimental and control groups. After anthocyanin supplementation, there was a significant difference in adjusted fasting plasma glucose levels. The group receiving 80 mg/d of anthocyanin had the lowest baseline-adjusted fasting plasma glucose when compared with placebo (F = 3.556, P = 0.007). Logarithmically adjusted plasma interleukin-10 levels were negatively correlated with increasing anthocyanin dose (F = 2.738, P = 0.025). Similarly, 8-iso-prostaglandin F2α levels decreased with increasing anthocyanins dose (F = 3.513, P = 0.009). Conclusions Taken together, our results suggest that anthocyanin supplementation at a dose greater than 80 mg/d is an effective antioxidant and antiinflammatory agent in healthy young adults. |
