💡 Smart Nutritional Guidance
Consumption advice
Eat a medium fruit sliced into stars, in a fruit salad or on its own; it is very hydrating and provides plenty of vitamin C and fibre with hardly any effect on blood sugar.
Best preparation methods
Wash the fruit and slice it straight into thin stars with its thin skin, and add a little fresh mint for extra freshness.
Important Nutritional Note
⚠️ Very important clinical warning: star fruit contains a neurotoxic compound called caramboxin and high levels of oxalate; people with kidney failure or on dialysis must not eat it at all, because damaged kidneys cannot clear this compound. For healthy people it is safe.
