Walnut intake interventions targeting biomarkers of metabolic syndrome and inflammation in middle-aged and older adults: a systematic review and meta-analysis of randomized controlled trials research protocol

Abstract

Review question / Objective: The aim of this study was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) in order to properly examine the evidence on the effects of walnut consumption on chosen indicators of inflammation and metabolic syndrome in mature adults. Condition being studied: Metabolic syndrome (MetS), chronic, low-grade inflammation, and oxidative stress are all important risk factors for morbidity and death, with a higher frequency in the elderly population. Information sources: We conducted a comprehensive search in five databases: Pubmed, EMBASE, Scopus, Cochrane, ClinicalTrials, from inception.
