This meta-analysis focused on the effects of aronia consumption on several cardiovascular risk markers. The authors included 7 studies in the meta-analysis, and focused on lipid profile, blood pressure, and inflammatory markers.

Results showed that aronia increases HDL lipoprotein (WMD = 1.48 mg/dL, 95% CI: 1.29 to 1.68) and diastolic blood pressure (WMD = 2.55 mmHg, 95% CI: 0.63 to 4.47). There were no effect on systolic blood pressure and inflammatory markers (CRP, TNF-α and IL-1). Reductions in cholesterol and LDL-cholesterol were noted for interventions less than 10 weeks in duration, whereas triglycerides were reduced for doses of 300 mg/day.

In conclusion, aronia intake is mainly associated with modulation of the lipid profile.
