Starfruit contains a neurotoxin called caramboxin, which can cause irreversible brain damage in large doses. If someone has intractable hiccups, the ER physician should ask if the patient has been eating star fruit.
In a cautionary video, “Kidney Stones and Spinach, Chard, and Beet Greens: Don’t Eat Too Much,” star fruit nephrotoxicity is discussed, leading to kidney damage. Even small amounts of star fruit can result in acute toxic effects, especially for those with kidney issues.
Another concern is the fruit’s neurotoxic effects, which are not well-known. Consumption of star fruit can lead to hiccups and, in severe cases, irreversible brain damage, especially for those with kidney problems.
For individuals with chronic kidney disease, star fruit should be avoided to prevent severe intoxication. Laws in Brazil alert people to these risks, and it is recommended that even those with normal kidney function should consider avoiding star fruit.
