About celeriac

A knobbly swollen hypocotyl of a celery variety grown for the root rather than the stalks. Peeled, it has a dense flesh that tastes of celery and parsley and holds its shape when cooked.

Also known as Celery root, Knob celery, Turnip-rooted celery

The evidence in depth

Best supported: Insufficient

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.

Heart Health
Insufficient evidence

Celery and celery seed extract are widely promoted for blood pressure on the strength of small studies of concentrated extracts and animal work. Celeriac itself has not been tested, and the extract literature is too small and too heterogeneous to carry across to the vegetable.

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: Celeriac, raw (USDA FoodData Central, FDC ID 170400).

% 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.

Nothing dependable is recorded about how preparation changes this food’s nutritional properties. Rather than guess, this section stays empty.

Things to know

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

  • Allergy

    Celery is a major allergen

    Celeriac is one of the recognised causes of severe food allergy in central Europe and must be declared as an allergen in the EU. Reactions range from oral itching to anaphylaxis, and the root is often a stronger trigger than the stalk. It cross-reacts with birch and mugwort pollen and with carrot.

  • Worth knowing

    Furocoumarins and sunlight

    Celery-family plants contain furocoumarins, which can cause a blistering rash where sap meets skin that is then exposed to sunlight. This is an occupational issue for harvesters rather than a risk from eating the root.
