Effects of water-soluble extract of açaí (Euterpe oleracea Mart.) on Wistar rats with induced obesity, diabetes, and cholesterol





Glycemic index


Among the countless species found in the Amazon biome, açaí is valued for its characteristic flavor and high nutrient content; in particular, it has a high content of anthocyanins. The present study aimed to evaluate the effect of the water-soluble extract of açaí in rats induced to obesity, diabetes and cholesterol, being administered monosodium glutamate at a concentration of 4 mg/g of animal weight alloxan mg/kg in 0.9% salina by intraperitoneally. For the biological tests, these were composed with a total of 50 animals, divided into 10 groups, composed of 5 rodents each. The control group consisted of healthy rats fed on commercial food. The determination of the proximal composition, dietary fiber and anthocyanin in the açaí extract was carried out. This extract was then supplemented in the feed for the different types of model animals that remained in feedlot for 28 days. The characterization of the açaí extract revealed high levels of insoluble dietary fiber (3.31 g / 100 g) and anthocyanin (45 mg / 100 g). There was also a positive effect on feed supplementation during the 28 days of confinement, with a reduction in weight and glycemic index observed in animals (p < 0.05).
