About turnip

The swollen root of the same plant that produces turnip greens, usually white-fleshed with a purple shoulder. Young roots are mild enough to eat raw; older ones become fibrous and are cooked.

Also known as White turnip, Neep, Navet

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.

Insufficient evidence

The turnip root is folded into cruciferous vegetable intake in cohort studies but has never been examined on its own. There is no dependable human research on the root and any cardiovascular outcome.

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: Turnips, raw (USDA FoodData Central, FDC ID 170465).

% 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.

  • boiledReduces glucosinolates

    Boiling leaches glucosinolates into the cooking water, which is part of why boiled turnip tastes far milder than a raw one.

Things to know

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

  • Worth knowing

    Goitrogens at high intake

    Turnip contains progoitrin, which yields goitrin on breakdown. Goitrin interferes with thyroid hormone synthesis more directly than the thiocyanates in leafy brassicas, though the amounts in ordinary portions are small and cooking reduces them.

  • Too much

    Fermentable carbohydrate

    Turnip carries fructans and is restricted in the elimination phase of a low-FODMAP diet. Bloating and wind are the usual complaint at larger servings.
