Ackee fruit is primarily associated with the Caribbean region. It is a popular fruit in Jamaica, where it is the national fruit and is a key ingredient in many local dishes. The fruit is also commonly found in other Caribbean countries such as Barbados, Trinidad, and Tobago. While it is enjoyed for its unique taste and nutritional benefits, it is important to note that eating unripe Ackee fruit can be dangerous and can lead to serious illness or even death.
