Those with a history of kidney stones or existing kidney disease should limit or avoid star fruit consumption.
For people with compromised kidney function, the fruit’s oxalate content can lead to kidney damage. In severe cases, star fruit toxicity can cause acute kidney injury. Individuals undergoing dialysis are particularly at risk and should refrain from eating star fruit.
Neurotoxin Effects and Drug Interactions
Star fruit contains caramboxin, a neurotoxin that can cause neurological problems in some people. This compound may lead to confusion, seizures, and other neurological symptoms, especially in those with kidney disease.
The fruit can interact with certain prescription drugs, potentially altering their effectiveness. It may affect blood glucose levels, making it important for people with diabetes to monitor their consumption. Star fruit can also interfere with some cholesterol-lowering medications.
