6种全谷物对大鼠盲肠微生物的影响

he effects of six whole grains (whole wheat, brown rice, oat, buckwheat, millet, foxtail millet) on the caecal microbes were explored in rats. The results showed that the content of short chain fatty acids in caecal contents of whole grains group was significantly higher than that of control group (P <0.05). The total short chain fatty acid content in buckwheat group was the highest (37.89mmol / L). High-throughput sequencing was used to analyze the caecal bacteria in rats，the results showed that 6 phyla were more than 1% abundance, and the three main phyla were Firmicutes, Verrucomicrobia and Bacteroidetes. The ratio of Bacteroides and Firmicutes in the whole grain groups were higher than that control group, and the ratio of the brown rice group was the highest(0.09), which indicated that whole grain had a certain effect on body weight control. The relative abundance of Lactobacillus in whole grains was higher than that of the control group. The relative abundance of Escherichia of in the whole grain group was lower than that of the control group，except the millet group. Whole grains can improve the intestinal environment and regulate intestinal microbiota. In addition，the gain ratio of whole grain groups were also higher than control group, which means that whole grains have the effects of controlling body weight.
