Summary

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

Conditions

• Overweight (BMI > 25)

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Pecan nut oil supplementation	Pecan nut oil will be administered as a dietary supplement by oral intake in a standardized daily dose of 30 mL/day for 60 days. The oil will be obtained through cold pressing, ensuring minimal processing and preservation of its bioactive compounds, particularly unsaturated fatty acids and antioxidants constituents. This intervention is distinguished from conventional dietary interventions by the use of a regionally sourced pecan nut oil with defined physicochemical and oxidative stability characteristics, allowing for controlled evaluation of its nutraceutical potencial. Unlike general dietary modifications, this study focuses on a single, standardized bioactive source to specifically assess its role in modulating inflammatory biomarkers and metabolic parameters in adults with overweight.
