    • Western Diet:
      • The least microbial diversity in this study was observed for adult Americans
      • the genus Prevotella was underrepresented
    • WHOLE GRAIN PRODUCTS
      • proportion of Lactobacillus/Enterococcus group was increased
      • barley flakes, brown rice flakes, or a mixture of both increased microbial diversity, as well as a rise in the proportion of Firmicutes and a reduction of the Bacteroidetes phylum
      • barley:a higher abundance of Blautia and Roseburia and a lower abundance of Bacteroides.
      • white bread vs rye bread: numbers of Bacteroidetes decreased, whereas levels of Clostridium cluster IV, Collinsella, and Atopobium spp. increased.
    • FRUITS AND NUTS
      • an increased amount of Bifidobacterium spp. in the feces of volunteers after blueberry drink consumption.
      • increase of the Bifidobacterium genus after consumption of red berries
      • consumption of red wine and de-alcoholized red wine the abundance of Bifidobacterium,Enterococcus, Eggerthella lenta, and the phylum Fusobacteria were increased compared to baseline values (most effects were more pronounced after red wine consumption)
