Effects of supplementation with kombucha and green banana flour on Wistar rats fed with a cafeteria diet

Abstract

Introduction With the increase of chronic diseases as a consequence of the population's eating habits, there is also a growing interest in foods rich in bioactive compounds capable of mitigating these diseases. Thus, this study aimed to evaluate the effects of supplementation with kombucha and green banana flour (GBF) on Wistar rats fed with cafeteria diet (CAF). Methods The animals were randomized into five groups of seven animals each, which were fed with the following diets: Treatment 1 (T1): Control treatment/commercial feed; Treatment 2 (T2): cafeteria diet (CAF); Treatment 3 (T3): CAF + kombucha; Treatment 4 (T4): CAF + green banana flour (GBF); Treatment 5 (T5): CAF + GBF + kombucha. Daily weight gain, daily food consumption, feed conversion, blood glucose, total cholesterol and fractions, triglycerides, liver enzymes, antioxidant activity, and body composition were evaluated. Results T5 presented lower feed intake and less weight gain. Liver histology revealed vacuolization in all treatments except T1, which was confirmed by the results of liver enzymes. There was no increase in blood glucose, and changes were observed in the lipid profile of the animals. T1 had the lowest body fat and the highest protein levels. Differences were observed for the antioxidant capacity in the liver of animals among treatments. Conclusion The intake of cafeteria diet altered the lipid and liver profile of the animals and the consumption of kombucha and GBF did not prevent these changes. The high polyphenols level of kombucha did not exert a hepatoprotective effect as an antioxidant. However, this supplementation generated greater satiety in the animals, leading to less weight gain until the end of the experiment.

Adult Ossabaw Pigs Prefer Fermented Sorghum Tea over Isocaloric Sweetened Water

“…For the first experiment, the only behavioral measure that was influenced by choice was the non-oral behavior duration measure. Non-oral behaviors could be interpreted as refractory, or rather, satiety behaviors [63]. In appetitive behavioral analyses, animals exhibit three states: first, appetitive (i.e., exploratory), then consumption, which is followed by a refractory period [63].…”

In appetitive behavioral analyses, animals exhibit three states: first, appetitive (i.e., exploratory), then consumption, which is followed by a refractory period [63]. In essence, the consumption of the teas and durations of head-in-bowl were great and similar among all tea types offered, and the non-oral behaviors displayed near the white tea bowl indicate either: (1) a level of satiety, or (2) a greater interest in the sumac-based teas.…”

Green Banana Flour Technology: from Raw Material to Sensory Acceptance of Products Made with Green Banana Flour in the Brazilian Scenario

“…The high resistant starch (AR) content of unripe banana fruits shows health benefits through their prebiotic function. AR is not absorbed in the intestine, but it is metabolized by the bacteria of the intestinal flora, producing chain fatty acids, resulting in a decrease in colonic pH, leading to beneficial effects on glucose and lipid metabolism [8,9].…”
