Abstract
|
|
|
|
This systematic review and meta-analysis aim to evaluate the association of wheat germ interventions and metabolic markers. An electronic search was performed by mid-May 2019 in the PubMed, Google Scholar, and Web of Science databases. Quality was evaluated using the risk of bias assessment tools. Thirty-three randomized controlled trials (RCTs) were identified, among which ten were suitable and systematically reviewed based on biomarkers (cholesterol, triglycerides, glucose, and oxidative stress). Three biomarkers in five eligible studies were investigated by meta-analysis. Total cholesterol showed non-significant results (p?=?0.98), with standard mean difference (SMD) of ??0.01 (95% confidence interval; ??0.17, 0.16). The SMD was ??0.06 (95% CI ??0.41, 0.29, n?=?4) for triglycerides and ??0.09 (95% CI ??0.62, 0.45, n?=?2) for glucose. No biomarkers showed heterogeneity (0%). This review revealed non-significant association between wheat germ interventions and metabolic markers. Sensitive analysis with high-quality RCTs may be worth trying.
