Effects of soy consumption on serum adiponectin and leptin levels: An umbrella review of meta-analyses based on randomized controlled trials.

The therapeutic effects of soy consumption on adipokine concentrations have yielded inconsistent results in previous meta-analyses. This umbrella meta-analysis aims to investigate the impact of soy and its isoflavones on serum adiponectin and leptin levels in adults. We searched the Cochrane Central, Web of Science, PubMed, and Scopus databases until October 10, 2024.
