Abstract

Purpose of ReviewWe identified and quantified the results of randomized controlled trials (RCTs) that have assessed the impact of egg consumption on blood pressure in adults.Recent FindingsWe conducted a comprehensive search of medical bibliographic databases up to February 2019 for RCTs investigating the effect of egg consumption on blood pressure in adults. Fifteen RCTs were included with a total of 748 participants. Overall, egg consumption had no significant effect on systolic blood pressure (weighted mean difference (WMD) = 0.046 mmHg; 95% CI − 0.792, 0.884) and diastolic blood pressure (WMD = − 0.603 mmHg; 95% CI − 1.521, 0.315). Subgroup analyses had no effect on pooled results and no heterogeneity was found among included studies.SummaryEgg consumption has no significant effects on systolic and diastolic blood pressure in adults. Due to several limitations among existing studies, general conclusions cannot be drawn regarding the beneficial or neutral impact of egg consumption on blood pressure in adults.
