Overview

Narrative review integrates evidence on palmitoleic acid effects on metabolic health, suggesting cautious interpretation of findings.

Key Points

  • This review aims to evaluate the role of palmitoleic acid in metabolic health through various types of evidence.
  • Integrative review of observational, clinical, and mechanistic studies concerning palmitoleic acid.
  • Assessment of effects on lipids, insulin resistance, inflammation, and liver and adipose tissue endpoints.
  • Observational studies link higher palmitoleic acid levels to insulin resistance and fatty liver.
  • Human interventions show mixed results, with some improvement in cholesterol but no clear benefit from purified palmitoleic acid.
  • Preclinical research suggests palmitoleic acid influences insulin signaling and lipid metabolism, but clinical benefits remain unverified.
