3.4. Association between SCFAs and Gut Microbiota
The relative abundance of the 42 genera of gut microbiota in each group was assessed, with the top 20 genera having the highest and lowest percentage changes, along with common bacteria identified in our previous report [As depicted in As shown in In According to the changes in SCFAs concentrations presented in Interestingly, at the 35-week follow up, propionate concentration increased in the PS and Control groups but decreased in the WE group. The results show that propionate-producing bacteria, including two genera, Finally, total SCFA content, encompassing acetate, propionate, and butyrate, demonstrated relative stability within the WE group when compared to the PS and Control groups. Although there was an increasing trend from baseline, it did not achieve statistical significance. In summary, the Firmicutes phylum (
