Africa has a long history of banana cultivation. Phytolith discoveries in Cameroon dating to the first millennium BCE triggered an as yet unresolved debate about the date of first cultivation in Africa. There is linguistic evidence that bananas were known in Madagascar around that time. The earliest prior evidence indicates that cultivation dates to no earlier than late 6th century AD. It is likely, however, that bananas were brought at least to Madagascar if not to the East African coast during the phase of Malagasy colonization of the island from South East Asia c400CE.
Here we have a simple, healthy drink made with just 1 banana. Idea from The 80/10/10 Diet by Dr. Douglas N. Graham, a cool raw food book.
