About jujube

A small oval fruit that eats like a crisp apple when fresh and like a date once dried and wrinkled. Long used across China, Korea and the Middle East, mostly in dried form and in infusions.

Also known as Chinese date, Red date, Hong zao, Annab

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.

Bowel regularity

Gut & Digestive Health
Insufficient evidence

Evidence is limited to one or two small trials of jujube extract in constipation, which are not enough to establish an effect. The fibre content of the dried fruit is real, but that is a compositional fact rather than a tested outcome.

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

Sleep
Insufficient evidence

Jujube has a long traditional association with sleep, but the human trials that exist test seed extracts and herbal formulas rather than the fruit, and they are small and poorly controlled. Nothing about eating jujube fruit follows from them.

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: Jujube, raw (USDA FoodData Central, FDC ID 168151).

% 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.

  • Worth knowing

    The fruit is not the seed preparation

    Most traditional-medicine research described as jujube concerns suanzaoren, the seed of Ziziphus jujuba var. spinosa, used for sleep. That is a different preparation with a different compound profile from the fruit sold as food.

  • Too much

    Dried jujube is sugar-dense

    The dried red dates that dominate the market are concentrated in sugar, and they are commonly eaten by the handful in soups and teas.

  • Interaction

    Sedative additivity is plausible but untested

    Because jujube seed preparations are used for their sedative effect, combining concentrated jujube products with sedative medicines is often cautioned against. No human interaction study has been done, and this does not apply to eating the fresh fruit.
