In conclusion, the results of our study support the hypothesis that high intake of both RS and AX [wheat/rye fiber] is capable of changing the intestinal microbiota and SCFA production in subjects with MetS in contrast with a low-fibre diet (WSD). Most distinctly, Bifidobacterium was clearly enriched by the HCD [High-fiber diet], which was in strong agreement with the increased faecal acetate concentration. Also, dysbiotic changes observed during the WSD [low fiber] emphasise the need for balanced diets, including fiber from various sources.
In other words...We are sorely missing fiber. What kind and how much is the million dollar question. But these researchers seem to like Raw Potato Starch, Hi-Maize Corn Starch, and wheat fiber. Let's discuss.
