About jackfruit

The largest tree-borne fruit in the world, made up of many sweet yellow bulbs around a fibrous core. Ripe fruit is eaten as fruit; unripe green jackfruit is cooked as a starchy vegetable and used as a meat substitute.

Also known as Jack fruit, Kathal, Nangka

The evidence in depth

Best supported: Limited

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.

Blood glucose response

Blood Sugar & Metabolic Health
Limited evidence

Evidence is limited and concerns green jackfruit flour rather than the ripe fruit. A small number of trials in people with type 2 diabetes report lower HbA1c when the flour replaces part of the usual staple. The studies are few, small and mostly from one region.

Limited evidence. Early human work, or mostly lab and animal research.

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: Jackfruit, raw (USDA FoodData Central, FDC ID 174687).

% 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

    Latex-fruit syndrome

    Jackfruit is a classic latex cross-reactive fruit and its sap is a sticky latex. Reactions in people allergic to natural rubber latex, and cross-reactions with birch pollen, are both documented, and anaphylaxis has been reported.

  • Too much

    Sugar load in ripe fruit

    Ripe jackfruit bulbs are notably sweet, and the portion sizes people eat are generous. Green jackfruit is a different proposition entirely, being starchy rather than sugary.

  • Worth knowing

    Potassium in advanced kidney disease

    Jackfruit is high in potassium, and it is one of the fruits usually restricted in stage 4 or 5 chronic kidney disease.
