Sugar Apple Flesh Is Edible; Its Seeds Are Toxic

Sugar Apple / Custard Apple — น้อยหน่า (noi-na) — Annona squamosa.

Eat only the ripe flesh; the seeds and bark contain neurotoxic annonaceous acetogenins and must be discarded. The flesh provides vitamin C, potassium, vitamin B6, magnesium, and fiber. A warm coconut-milk dessert pairs the ripe flesh with toasted mung beans, while frozen custard-apple and butterfly-pea pops make a cooling snack. The fruit ripens quickly and bruises easily.

Narration transcript

Opening

Scoop this one open with a spoon and the flesh eats like sweet, grainy custard — but the shiny black seeds tucked inside are toxic, and so is the bark. Custard apple — น้อยหน่า, noi-na. Only the ripe flesh is food; you scoop it out and spit every seed.

น้อยหน่าน้ำกะทิ (Noi Na Nam Kathi)

Noi na nam kathi is a sweet coconut-milk dessert eaten warm with a spoon, perfectly paired with toasted mung beans for a crunchy contrast.

ไอศกรีมน้อยหน่าอัญชันนมสด (Noi Na Anchan Nom Sot Ice Cream)

Noi na anchan nom sot is a refreshing custard apple and butterfly pea ice pop eaten frozen on a stick, making it a perfect match for hot afternoons.

Nutrition summary

That sweet custardy pulp gives you solid vitamin C and fiber, plus a little vitamin B6.

Vitamin C

Vitamin C is used to build collagen and helps protect cells from oxidative stress.

Potassium

Potassium helps with normal fluid balance and muscle function.

Vitamin B6

Vitamin B6 contributes to normal energy metabolism, supports a healthy nervous system, and helps your body make red blood cells.

Magnesium

Magnesium supports normal muscle and nerve function, contributes to normal energy metabolism, and helps maintain healthy bones.

Fiber

Fiber adds bulk to meals and can help with fullness.

Closing

So eat the ripe flesh and discard every seed. The seeds and bark hold annonacin — a nerve toxin that, eaten heavily over years, has been linked to a Parkinson's-like illness, so never grind or swallow them. The ripe fruit bruises the moment it softens, so handle it gently and eat it fresh. Follow Longevity Biome, and LIKE this video for regular updates.
