Inulin-type fructans: health benefits and safety
What it found
Inulin-type fructans are changed by gut bacteria and may help digestion, metabolic syndrome, the immune system and inflammation, and may help prevent infection and cancer.
But too little of them has been linked to worse fatty liver disease, gut symptoms, liver cancer and gut inflammation.
What they found
Studies in people and animals
Possible health benefits
The paper reports that inulin-type fructans improve the digestive system, metabolic syndrome, the immune system and inflammatory diseases. It also reports they may help prevent infection and cancer.
Too little may be harmful
The paper reports that not eating enough inulin-type fructans makes non-alcoholic fatty liver disease worse. It also reports links to gut symptoms, liver cancer and gut inflammation.
Other findings
What they are
Inulin-type fructans are a mix of inulin, oligofructose and fructooligosaccharide. They are soluble dietary fibre and are used as functional ingredients.
Gut bacteria change them
Gut bacteria modify inulin-type fructans at the end of the ileum. This is part of how they are thought to act in the body.
What the authors conclude
“Therefore, this review summarizes the health benefits, pharmaceutical applications and safety evaluation of ITFs, which would direct their rational applications.”
Also in their conclusions
- They summarize the health benefits, pharmaceutical applications and safety evaluation of inulin-type fructans.
- They say this would direct their rational applications.
How it was done
The authors wanted to bring together what is known about the health benefits, pharmaceutical uses and safety of inulin-type fructans, to guide how they should be used.
What it can’t tell you
- We summarised it from the abstract only.
- This is a summary of other research, not a new study. It cannot show cause and effect.
- The paper does not give amounts, groups or time frames, so it cannot say how much inulin-type fructans a person should eat.
