Impact of dietary anthocyanins on systemic and vascular inflammation: Systematic review and meta-analysis on randomised clinical trials
Food and Chemical Toxicology (2020)
- This is a meta-analysis of the use of dietary anthocyanins on inflammation (so this is not elderberry-specific). Elderberries are high in anthocyanins so this study has potential ramifications for the benefits of elderberry regarding general inflammation.
- The meta-analysis showed that CRP, IL6, TNF, adiponectin, and VCAM1 (all pro-inflammatory cytokines) were all significantly lower after administration of anthocyanins, and the studies showed low inter-trial heterogeneity and good trial quality.
- Similarly, adiponectin levels were higher with the same study quality notes as above.
- CRP, IL6, TNF and VCAM1 levels were lower with higher doses of anthocyanins.
- This is the opposite finding of many of the primary in vitro studies evaluated and also inconsistent with the RCTs of antiviral and antibacterial exposure. Not clear why this is.
