Cassava isn't native to Africa. It's a New World food that was imported
there (along with potato) from the Americas during the very early slave
trade era. It requires much processing to be made edible/nutritious--i.e.,
get rid of the cyanogenic glucosides and phytates.
It's thought-provoking how many truly "marginal" foods throughout the world
have become redistributed and are now considered staples.
