Xylo- and isomalto-oligosaccharide mix tested in high-fat diet mice
What it found
In mice fed a high-fat diet, a mix of xylo-oligosaccharides and isomalto-oligosaccharides in a 1:3 ratio improved blood fat levels, insulin sensitivity and gut barrier function.
The work was done in animals, not people.
What they found
Animal and lab studies
Blood fats and insulin
The 1:3 mix reduced dyslipidemia, limited fat buildup outside normal storage sites, and improved insulin sensitivity in the mice.
Gut bacteria changes
The mix increased beneficial gut bacteria such as Coriobacteriaceae UCG-002 and reduced groups linked to inflammation, including Enterorhabdus, Streptococcus and Colidextribacter.
Bile acid profile
The 1:3 mix changed the bile acid profile, raising levels of bile acids that were inversely linked to gut inflammation markers.
Colitis and gut barrier
The mix eased colitis symptoms by lowering fecal calprotectin and inflammatory markers, and improved the gut barrier by increasing mucin and tight junction proteins.
What the authors conclude
“Collectively, the XOS:IMO (1:3) formulation demonstrated therapeutic potential for metabolic regulation and dietary inflammation prevention through gut microbiota-bile acid crosstalk modulation.”
Also in their conclusions
- They conclude that the XOS:IMO (1:3) formulation shows therapeutic potential for metabolic regulation and dietary inflammation prevention.
- They say this works through gut microbiota-bile acid crosstalk modulation.
How it was done
The authors wanted to see how different ratios of xylo-oligosaccharides and isomalto-oligosaccharides affect fat processing, gut bacteria, bile acids and the gut lining in mice fed a high-fat diet.
They fed mice a high-fat diet and tested different ratios of xylo-oligosaccharides to isomalto-oligosaccharides. The 1:3 ratio was the one they report on in detail.
