Inulin, its plant sources and reported health benefits
What it found
Inulin is a soluble fiber found in over 36 000 plants that feeds helpful gut bacteria.
It is also linked to lower blood sugar, weight loss and better mineral absorption.
What they found
Studies in people and animals
Gut bacteria
Inulin acts as a prebiotic. It encourages the growth of helpful bacteria in the gut.
Blood sugar and weight
Inulin helps lower blood sugar levels. It also supports weight loss and helps control how the body handles fats.
Colon cancer risk
Taking inulin may lower the chance of developing colon cancer. It also reduces signs of inflammation in the body.
Minerals and digestion
Inulin improves how well the body absorbs minerals. It also helps relieve constipation.
Mood effects
Inulin may help ease symptoms of depression.
Other findings
Where inulin comes from
Inulin is a soluble fiber stored in more than 36 000 plant species. Jerusalem artichoke tubers and chicory roots are the main raw materials used by the food industry.
What the authors conclude
- They present inulin as a fiber with wide-ranging benefits for gut bacteria, metabolism and overall health.
- They note it is commonly sourced from chicory roots and Jerusalem artichoke tubers for use in foods.
How it was done
The authors wanted to gather everything known about what inulin does in the body and where it comes from.
They gathered and summarized existing research on inulin. The summary covers its natural sources, how the food industry uses it, and its effects on health.
What it can’t tell you
- We summarised it from the abstract only.
- This work gathers past studies rather than testing inulin directly. It cannot prove that inulin causes these health changes on its own.
- Some of the benefits described may come from animal or lab tests. Those results do not always match what happens in people.
