Effect of Beetroot Consumption on Serum Lipid Profile: A Systematic Review and Meta-Analysis

Abstract

Beetroot has recently become very popular among people as a medicinal superfood that decreases blood pressure and improves athletes' performance. The present meta-analysis aimed to investigate the effect of beetroot consumption on serum lipid profile. A literature search was conducted covering PubMed, ISI Web of Science, Scopus, and Google scholar of English human subject randomized clinical trials (RCT) up to December 2020. Pooled results showed that beetroot consumption had no significant effect on any of the variables. The mean difference (95 CI) between intervention and control groups for TC was 1.25 (-0.03, 2.53), for TG -0.47 (-1.16, 0.21), for HDL 0.54 (-0.13, 1.21) and for LDL was -0.48(-1.04, 0.09). Subgroup analysis by the health condition of subjects, the form of beetroot consumption, and type of intervention showed no significant differences. It can be concluded that beetroot cannot be categorized as an effective supplementation for adjustment of lipid profile.
