About chicory root

The taproot of the chicory plant, roasted as a coffee substitute and extracted industrially as the main commercial source of inulin. It is bitter, fibrous and rarely eaten as a plain vegetable.

Also known as Chicory, Succory, Coffee chicory, Radichetta root

The evidence in depth

Best supported: Moderate

What each association actually rests on, and the papers behind it. A rating describes the state of the research, not how impressive the food is. How we rate evidence.

Bowel regularity

Gut & Digestive Health
Moderate evidence

Chicory-derived inulin increases stool frequency and softens stool consistency across a substantial body of randomised trials, and this is one of the few food-fibre effects that regulators have accepted. The effect is modest, it depends on dose, and the same fermentation causes the wind that leads many people to stop taking it.

What may be going on: Fermentation of inulin in the colon increases bacterial mass and water retention in the stool, and short-chain fatty acid production stimulates motility.

Moderate evidence. Several human studies point the same way, with real caveats.

Gut microbiome

Gut & Digestive Health
Moderate evidence

Chicory inulin raises faecal bifidobacteria reliably in controlled trials, which is about as reproducible as prebiotic findings get. Whether that shift produces any clinical benefit is a separate question that the trials mostly do not answer.

Moderate evidence. Several human studies point the same way, with real caveats.

Blood glucose response

Blood Sugar & Metabolic Health
Insufficient evidence

Chicory root extracts are marketed for blood sugar on the strength of animal studies and the fact that inulin itself is not digested. Human trials measuring glycaemic outcomes after chicory root are few and do not agree.

Insufficient evidence. Not enough human research to say anything useful yet.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Chicory roots, raw (USDA FoodData Central, FDC ID 169993).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

Bioactive compounds

Compounds present in meaningful amounts. Presence is banded rather than quantified, because whole-food levels vary enormously with variety, growing conditions, storage and preparation.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

  • roastedReduces inulin

    Roasting for coffee substitute caramelises and partially degrades the inulin into shorter fructans and sugars, which is where the bittersweet roasted flavour comes from. Roasted chicory is not equivalent to the raw root.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Too much

    Chicory root fibre is a leading cause of bloating in fortified foods

    Chicory root fibre is added to bars, yoghurts and low-sugar products to raise their fibre figure. It ferments rapidly and is one of the most common reasons people report severe wind and cramping from a food they assumed was gentle. Reading for chicory root fibre or inulin on the ingredient list is often the whole explanation.

  • Allergy

    Inulin and chicory allergy

    Anaphylaxis to inulin and to chicory has been documented, mostly in people already sensitised to the daisy family or to birch and mugwort pollen. It is rare but it is real, and it is easy to miss because inulin is an unlabelled-seeming ingredient.

  • Worth knowing

    Not the same thing as chicory leaves

    Radicchio, Belgian endive and chicory greens come from the same species but have entirely different composition. This page describes the root.
