Investigating how different fatty acids affect gut microbiota metabolites

Production of Gut Microbiota-Derived Metabolites in Response to Different Fatty Acid Profiles

Not applicable Interventional Laval University · NCT05917132

This study is testing how different types of fats in our diet affect the gut bacteria and their production of certain substances in people with and without obesity and Type 2 diabetes.

What this trial studies

This project aims to explore how the gut microbiota produces metabolites in response to diets rich in either saturated or polyunsaturated fatty acids. It will measure the production of these metabolites over a two-day dietary intervention in individuals with and without obesity and Type 2 diabetes. The study focuses on understanding the role of gut microbiota-derived metabolites, particularly endocannabinoids, in metabolic health. Participants will be monitored for changes in metabolite production following the dietary changes.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 45 to 65 with a BMI between 20 and 35 who are generally healthy and have a moderate diet quality score.

Not a fit: Patients with intestinal pathologies, significant recent weight changes, or those on certain medications or supplements may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new dietary recommendations for improving metabolic health in individuals with obesity and Type 2 diabetes.

How similar studies have performed: While the specific approach of this study may be novel, previous research has shown that dietary interventions can significantly impact gut microbiota and metabolic health.
