Frequently Asked Questions

Can everyone eat starfruit?

No—starfruit contains caramboxin, a neurotoxin that healthy kidneys filter out but damaged kidneys cannot. People with kidney disease should completely avoid starfruit as it can cause serious neurological symptoms. If you have kidney issues, do not eat this fruit.

Do I peel starfruit before eating?

No peeling needed! The entire starfruit is edible—waxy skin, flesh, and tiny seeds. Just wash well, slice crosswise into stars, and optionally trim the brown edges of the ridges. The whole fruit has a pleasant crisp texture.

How do I know when starfruit is ripe?

Look for bright yellow color with slight browning on the ridges (not the flat parts). Green fruit is unripe and very sour. Ripe starfruit gives slightly when pressed and has a mild fragrant smell. Some brown on ridges indicates peak sweetness.
