Is Star Fruit Dangerous To Eat?

For most healthy individuals, star fruit is safe and beneficial. However, there are important exceptions:

Kidney Disease Concerns

• Caramboxin: A neurotoxin that healthy kidneys filter out effectively, but can build up to dangerous levels when kidney function is impaired

Medication Interactions

Like grapefruit, star fruit can also interact with some prescription medications by inhibiting cytochrome P450 enzymes, which are crucial for the metabolism of these medications. This interaction might elevate the dose of these medications in your body to potentially dangerous levels. If you are taking prescription drugs, particularly bosutinib, panobinostat, or venetoclax, please consult your doctor before consuming star fruit.

Other Considerations

• Digestive sensitivity: The natural acidity may cause discomfort for those with sensitive stomachs or acid reflux, especially when consumed on an empty stomach

• Allergies: Though rare, some individuals may be allergic to star fruit and should avoid it
