Functional low‑GI versus standard wholegrain carbohydrates for adults with moderately high triglycerides

Randomized, Double-Blind, Placebo-Controlled Crossover Clinical Trial to Evaluate the Effect of a Functional Low-Glycemic Index Carbohydrates Versus Standard Wholegrain Carbohydrates on Glycolipid Metabolism and Vascular Stress Markers in Subjects With Suboptimal Triglyceridemia

Not applicable Interventional University of Bologna · NCT07198789

This study will test whether swapping standard wholegrain carbs for functional low‑GI bakery foods within a Mediterranean diet helps improve the triglyceride‑glucose index and vascular stress markers in adults with suboptimal triglyceride levels.

What this trial studies

This is a randomized, double‑blind, crossover trial comparing a functional low‑glycemic‑index (Altograno®) bakery intervention with standard wholegrain bakery foods, both delivered as part of a Mediterranean dietary pattern. Adults with triglycerides over 150 mg/dL will follow each diet arm for a defined period with washout between arms, while researchers measure the Triglycerides‑Glucose Index and blood markers of vascular stress and inflammation. The crossover design means each participant receives both interventions in random order, which increases within‑person comparison power. Key exclusions include celiac disease, BMI over 30 kg/m2, and unstable preventive medications.

Who should consider this trial

Good fit: Adults aged 18 or older with fasting triglycerides >150 mg/dL who can attend visits at the Bologna clinic and are not living with celiac disease or BMI over 30 are ideal candidates.

Not a fit: People with BMI >30 kg/m2, diagnosed gluten hypersensitivity/coeliac disease, or those on recently changed preventive medications are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the intervention could modestly lower metabolic risk markers and reduce long‑term risk for diabetes and cardiovascular disease.

How similar studies have performed: Previous randomized and cohort studies of low‑GI diets have shown modest improvements in fasting glucose, HbA1c and lipid measures, so this dietary approach has supporting evidence though results are incremental.
