Bananas have been around for a long time. Since the banana grows in tropical regions, generally they were only eaten by the people that lived in those regions. Antonius Musa was a Roman doctor that suggested that Augustus Caesar eat them. The first bananas were grown in Africa but sailors brought them to the Canary Islands and West Indies. Jean Francois Poujot of Jamaica found that some of his bananas were yellow instead of the usual red or green. The sweet yellow banana caught on and was soon the preferred banana. Now the other types of bananas are usually called plantains.
