Dietary habits strongly influence gut microbiota. The aim of this study was to compare and correlated the abundance of Firmicutes and Bacteroidetes phyla, some representative bacteria of these phyla such as Bacteroides thetaiotaomicron, Prevotella, Faecalibacterium prausnitzii, Clostridium leptum and Bifidobacterium longum as a member of Actinobacteria phylum in young adults with their food intake. Faecal samples used came from lean subjects (BMI = 19.83 ± 0.94 kg/m(2)), overweight (BMI = 27.17 ± 0.51 kg/m(2)) and obese (BMI = 41.33 ± 5.25 kg/m(2)). There were significant differences in total studied gut microbiota between the overweight and lean groups. Members of the Firmicutes phylum, and Bifidobacterium longum, were more abundant in the lean group. The results suggest that diet rich in unsaturated fatty acids and fibre promote an abundant population of beneficial bacteria such as B. longum and Bacteroidetes. However, it has been considered that the results may be biased due to the size of the individuals studied; therefore the results could be only valid for the studied population.
饮食习惯对肠道微生物群有很大影响。本研究的目的是比较并关联年轻成年人中厚壁菌门和拟杆菌门的丰度，以及这些门的一些代表性细菌，如嗜热栖热放线菌、普氏菌、普拉梭菌、纤细梭菌和作为放线菌门成员的长双歧杆菌与他们的食物摄入量。所使用的粪便样本来自瘦人（BMI = 19.83 ± 0.94 kg/m²）、超重者（BMI = 27.17 ± 0.51 kg/m²）和肥胖者（BMI = 41.33 ± 5.25 kg/m²）。超重组和瘦人组之间在整个研究的肠道微生物群方面存在显著差异。厚壁菌门的成员以及长双歧杆菌在瘦人组中更为丰富。结果表明，富含不饱和脂肪酸和纤维的饮食会促进有益细菌如长双歧杆菌和拟杆菌的大量繁殖。然而，有人认为由于所研究个体的体型，结果可能存在偏差；因此，这些结果可能仅对所研究的人群有效。
