Official title
Supplementation With Vegetable Oils Enriched in the Fatty Acids Trans-C16:1 or Cis-C16:1: Dose-response Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Trans-palmitoleic acid (trans-C16:1) is a naturally occurring trans fatty acid present in small quantities in foods, most notably in dairy products. Observational evidence suggests a positive association between trans-C16:1 and insulin sensitivity, and negative association with risk of developing type 2 diabetes mellitus \[1-3\]. Cis-palmitoleic acid (cis-C16:1) is found naturally in foods and is particularly high in macadamia nuts and oil extracted from the sea buckthorn plant. Animal models suggest that this palmitoleic acid isomer also improves insulin sensitivity and reduces metabolic dysfunction. This pilot dosing study is necessary to inform the design of a larger trial to test the hypothesis that both trans-C16:1 and cis-C16:1 improve insulin resistance but at different doses. Plasma phospholipid fatty acid profiles will be used as the primary outcome measure.
