A diaspora is a dispersion of an originally homogeneous entity, such as language or culture.

The spread of African food started in the African culture. Africans brought food over to America with the help of Native Americans. The techniques that were used by African Americans were quickly woven into making dishes such as: collard greens, fufu, which is known today as candied yams. The food was made famous in many southern states such as: Chicago, Louisiana, and New Orleans. "Soul Food" quickly became well known and many would say that large consumptions of it would bring on un-healthy habits. Small consumptions eaten every once in a while would do no harm. "Soul Food" has made its way into self owned restaurants and churches. The flavors of "Soul Food" are mixed into the spices of peppers, salts, and grounded cumin. 

Rap music is not a fad, but a musical art form that has been around for over 20 years in the United States. In fact, one can trace the history of rap back to the West African professional singers/storytellers known as Griots. Back in the Africas, they used to beat on drums for rhythm, and they'd recite rituals which eventually led into rap music.
