Isomalto-oligosaccharide and xylo-oligosaccharide mix in mice on a high-fat diet
What it found
A specific mix of isomalto-oligosaccharides and xylo-oligosaccharides improved blood fats, insulin response, and gut health in mice eating a high-fat diet.
The best results came from a mix using one part xylo-oligosaccharides to three parts isomalto-oligosaccharides.
What they found
Animal and lab studies
Blood fats and insulin
In mice on a high-fat diet, the one-to-three mix improved blood fat levels and helped the body respond better to insulin. It also reduced fat building up in places it should not be.
Gut bacteria shifts
The same mix increased helpful gut bacteria in the mice. It also lowered types of bacteria linked to inflammation, including Enterorhabdus, Streptococcus, and Colidextribacter.
Bile acid changes
The mix changed the types of bile acids in the mice. Higher levels of certain bile acids were linked to lower signs of gut inflammation.
Gut lining and colitis
In the mice, the mix eased colitis symptoms and lowered inflammatory markers in their waste. It also strengthened the gut lining by boosting protective proteins.
What the authors conclude
- They conclude that mixing xylo-oligosaccharides and isomalto-oligosaccharides at a one-to-three ratio helps control metabolism in mice on a high-fat diet.
- They suggest this mix works by changing how gut bacteria and bile acids interact with each other.
- The authors say this formulation shows promise for preventing diet-related inflammation.
How it was done
The authors wanted to see how different ratios of these two fibre-like ingredients affect fat balance, gut bacteria, and gut lining damage caused by a high-fat diet.
They fed mice a high-fat diet and gave them different mixes of xylo-oligosaccharides and isomalto-oligosaccharides. They then measured changes in blood fats, gut bacteria, bile acids, and gut lining health.
What it can’t tell you
- We summarised it from the abstract only.
- These findings come from mice, so they cannot show what happens in people eating these ingredients.
- Scientists do not yet know if the same one-to-three ratio would have the same effects in humans.
