About pummelo

The largest citrus fruit, and one of the three ancestral species from which grapefruit, orange and lemon descend. A very thick pith surrounds firm, mildly sweet segments that separate cleanly.

Also known as Pomelo, Shaddock, Jabong, Youzi

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

Citrus flavanones have been studied for lipid effects, but pummelo specifically has almost no trial literature. Given its drug interaction profile, it is also not a sensible fruit to increase deliberately without checking medicines first.

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: Pummelo, raw (USDA FoodData Central, FDC ID 167754).

% 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.

  • Interaction

    Furanocoumarin drug interaction, as with grapefruit

    Pummelo is a parent species of grapefruit and carries the same furanocoumarins that irreversibly inhibit intestinal cytochrome P450 3A4. It can raise blood levels of statins, calcium channel blockers, some immunosuppressants and many other drugs, and case reports of raised INR on warfarin exist. A single serving can affect enzyme activity for a day or more, so timing doses apart does not avoid it. Check with a pharmacist before combining it with prescribed medicines.

  • Worth knowing

    Often mislabelled as grapefruit or vice versa

    Pummelo, pomelo and grapefruit are used loosely and sometimes interchangeably in shops. For the drug interaction question the distinction does not matter much, since both carry furanocoumarins.

  • Allergy

    Citrus peel oil reactions

    The thick peel is highly aromatic and its oils are a more common cause of contact and oral reactions than the flesh.
