Brief Summary
Low-glycemic index (GI) carbohydrates help prevent type 2 diabetes and cardiovascular disease by reducing postprandial glucose, insulin spikes, inflammation, and triglyceride synthesis. They improve weight, lipid profiles, and vascular health. Our study will compare functional low-GI vs. standard wholegrain carbs in a Mediterranean diet to assess their effect on the Triglycerides-Glucose Index, a marker of metabolic and cardiovascular risk, in subjects with suboptimal triglyceride levels.
