Anti-Inflammatory Effects of Pecan Nut Oil Supplementation in Adults With Overweight: A Randomized Controlled Parallel-Group Clinical Trial

The goal of this clinical trial is to evaluate whether daily supplementation with cold-pressed pecan nut oil can reduce inflammation in adults with overweight. The main questions it aims to answer are: Does pecan nut oil supplementation reduce inflammatory biomarkers, including C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α)? Does pecan nut oil supplementation improve biochemical parameters such as fasting blood glucose and lipid profile? Researchers will compare an experimental group receiving pecan nut oil to a control group with no intervention to determine its effect on inflammation and metabolic parameters. Participants will: Consume 30 g/day of cold-pressed pecan nut oil under fasting conditions for 8 weeks (experimental group) Maintain their usual diet and physical activity throughout the study Attend two evaluation visits (baseline and Day 60) for blood sample collection and anthropometric measurements Provide dietary information using a 24-hour dietary recall
