: Type 2 Diabetes Mellitus (T2DM) is characterized by hyperglycemia, increased risk of cardiovascular diseases, and oxidative imbalances. This study aimed to investigate the impact of dietary supplementations with 'Arinto' grape pomace flour (GPF) (WGPF) and 'Touriga Nacional' GPF (RGPF) in an animal model of T2DM. : T2DM was induced by a high-fat diet (HFD) for 28 days and a single dose of streptozotocin (STZ) (35 mg/kg) on the 21st day.
