Abstract

BACKGROUND & AIMS:

The impetus for the current study was to evaluate the efficacy of cranberry supplementation on cardiovascular disease metabolic risk factors in adult populations.

METHODS:

A systematic review was conducted on PubMed, Scopus, Web of Science and Google Scholar up to June 2018, to identify randomized controlled trials investigating the effect of cranberry supplementation on cardiovascular metabolic risk factors.

RESULTS:

The results of the pooled effect size indicated that cranberry administration significantly reduced systolic blood pressure and body mass index. No statistically significant change was observed in triacylglycerol, total cholesterol, low-density lipoprotein, high-density lipoprotein, fasting plasma glucose, fasting insulin, homeostasis model assessment of insulin resistance, diastolic blood pressure, waist circumference, C-reactive protein, and intercellular adhesion molecule. Stratified analysis showed that SBP reduction was more pronounced in studies with ≥50 mean age participants. Also, subgroup analysis suggested a significant increase in high-density lipoprotein concentrations in subgroups with subjects <50 mean age, and triacylglycerol levels in subsets with cranberry administered in juice form.

CONCLUSIONS:

This systematic review and meta-analysis suggests cranberry supplementation may be effective in managing systolic blood pressure, body mass index and high-density lipoprotein in younger adults. Further high-quality studies are needed to confirm these results.
