4. Ackee
If you’d like to experience “Jamaican Vomiting Sickness” nibble on an unripe or too ripe Ackee.
This national fruit of Jamaica is related to lychee. Ackee is rich in healthy fatty acids, a variety of vitamins and fairly low in calories. The taste is described a buttery and similar to hearts of palm.
The problem is that the seeds, and unripe and overripe flesh are poisonous. The side effects of eating improperly prepared fruit can cause seizures and fatal hypoglycemia.
