Adzuki bean paste consumption can reduce fat accumulation in rats by lowering energy intake and altering gut microbiota composition.
Animal Study Adzuki Bean Gut Microbiota Obesity
The study evaluated the impact of adzuki bean paste (ABP) on visceral fat accumulation in rats by administering different doses of ABP - 30% and 58.9% in their diets for a period of 28 days. ABP, being a good source of indigestible carbohydrates with fiber and resistant starch, forms an influential part of the rats' diet. The daily dietary energy intake was observed during this period, with particular attention to fecal lipid and fecal acidic sterol excretions, which were found to be increased in a dose-dependent manner. Certain observations within the body of the rats, including the condition of cecal content and fecal moisture, were also monitored.
In discussing the results of administrating ABP in the diet, it was observed that visceral fat accumulation and serum lipid levels were reduced. Both groups of rats - those given a diet with 30% ABP and those with 58.9% ABP - showed significantly higher cecal acetic, propionic, and n-butyric acids and lowered cecal pH, regardless of the ABP dose. The ABP diet also reflected altered microbial community data, with higher alpha-diversities than a control group. The study further revealed through cecal bacterial 16S rRNA gene sequencing that the ABP supplemented diets also impacted the ratio of two types of bacteria, Firmicutes, and Bacteroidetes. The findings hence suggest that the cecal fermentation of fiber and resistant starch in ABP was instrumental in reducing fat accumulation.
