The first inhabitants of Zanzibar were Bantus coming from mainland Tanganyika. They consisted of mostly fishers and their diet thus consisted of primarily seafood, such as tuna, mackerel, lobster, squid, octopus and oysters. Other ingredients and recipes brought by Bantus that are found in today's Zanzibari cuisine (some of which became widespread during European colonialism) are common beans, sweet potatoes, manioc chips, yam and plaintain.
