Abstract
The effects of un-extruded (UCP) and extruded cranberry pomace (ECP) on fecal fat excretion, liver index, lipid and carbohydrate metabolism, and inhibition of oxidative stress due to a high-fat diet (HFD) in rats were studied.
The Wistar rats for 8 weeks received one of the four diets: (1) control (modified the American Institute of Nutrition: AIN based diet containing 7% fat), (2) HFD (AIN based diet containing 30% fat), (3) HFD with 3% un-extruded (UCP) and (4) HFD with 3% (ECP).
Both UCP and ECP significantly improved the plasma antioxidant capacity and decreased lipid per- oxidation in rats fed a HFD. However, only the addition of 3% UCP into the HFD significantly increased the fecal lipid excretion and considerably decreased serum triglycerides level in rats.
Further investigation is needed to determine the role of an individual components present in UCP and ECP in the improvement of metabolic conditions observed in the current study.
