About sugar apple

A knobbly green Annona fruit that separates into segments of sweet, custardy white pulp, each around a black seed. Very sweet and highly perishable, so it is eaten close to where it grows.

Also known as Sweetsop, Custard apple, Sitaphal, Ata

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

Annona squamosa leaf extracts have been studied in animals for glucose effects, and that work is often cited as though it applied to the fruit. It does not, and there is no human trial of eating sugar apple.

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: Sugar-apples, (sweetsop), raw (USDA FoodData Central, FDC ID 168175).

% 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

    Annonaceous acetogenins

    Like soursop and cherimoya, sugar apple contains annonacin and related acetogenins that are neurotoxic in animal models and were implicated in an epidemiological cluster of atypical parkinsonism in Guadeloupe. Occasional eating of the pulp has not been shown to cause harm; heavy lifelong intake and leaf infusions are the concern.

  • Avoid

    Seeds are toxic and have caused eye injury

    Annona squamosa seed powder has traditional use as a pesticide and delousing treatment, and accidental contact with the eye has caused severe keratitis and blindness. Seeds must never be crushed or eaten.

  • Too much

    Among the sweeter fruits by weight

    The name is accurate. Sugar apple carries a high sugar concentration for a fresh fruit, and a whole fruit is a large portion for anyone managing blood glucose.
