Abstract:

There is an increasing interest in developing natural herb-infused functional beverages with health benefits; therefore, in this study, we aimed to evaluate the effect of strawberry, blueberry, and strawberry-blueberry blend decoction-based functional beverages on obesity-related metabolic alterations in high-fat and high-fructose diet-fed rats. The administration of the three berry-based beverages for eighteen weeks prevented the development of hypertriglyceridemia in obese rats (1.29-1.78-fold) and hepatic triglyceride accumulation (1.38-1.61-fold), preventing the development of hepatic steatosis. Furthermore, all beverages significantly down-regulatedhepatic expression, whereas the strawberry beverage showed the greatest down-regulation of, involved in fatty acid de novo synthesis. Moreover, the strawberry beverage showed the most significant up-regulation of hepaticand(fatty acidβ-oxidation). In contrast, the blueberry beverage showed the most significant down-regulation of hepaticand(fatty acid intracellular transport). Nevertheless, no beneficial effect was observed on biometric measurements, adipose tissue composition, and insulin resistance. On the other hand, several urolithins and their derivatives, and other urinary polyphenol metabolites were identified after the strawberry-based beverages supplementation. In contrast, enterolactone was found significantly increase after the intake of blueberry-based beverages. These results demonstrate that functional beverages elaborated with berry fruits prevent diet-induced hypertriglyceridemia and hepatic steatosis by modulating critical genes involved in fatty acid hepatic metabolism.
