Personalized plant-based diet to improve heart and metabolic health

Precision Nutrition to Improve Cardiometabolic Health With Dietary (Poly)Phenols (PRE-CARE-DIET)

Not applicable Interventional University of Parma · NCT06347094

What this trial studies

This study investigates how a personalized diet rich in (poly)phenols affects cardiometabolic health based on individual metabolism of these compounds. It involves recruiting 330 participants at risk for cardiometabolic issues, who will undergo an oral (poly)phenol challenge test to categorize them into different metabotypes. The study includes an observational phase to gather lifestyle data and an experimental phase where participants will be randomly assigned to either increase their (poly)phenol intake or maintain their usual diet. Various health metrics, including blood pressure and metabolic markers, will be monitored throughout the study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40-80 who are at risk for cardiometabolic diseases but have not been clinically diagnosed.

Not a fit: Patients with a BMI below 18.5 or above 34.9 kg/m², or those with a history of cardiovascular events or metabolic diseases, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to tailored dietary interventions that significantly improve cardiometabolic health in individuals.

How similar studies have performed: Previous studies have shown promise in personalized dietary interventions for improving health outcomes, but this specific approach focusing on (poly)phenol metabolism is relatively novel.
