Just want to address the bold
1) food: i don't know about that one. I don't see the influence of AA cooking/cuisine globally. Unless you are talking about soul food restaurants in other countries
2)fashion: outside hair (afros, etc. ) and hip hop wear/streetwear i also am not too sure about the impact of AAs in global fashion especially as most of the world follows European fashion
Southern barbecue and soul food are distinct culinary forms recognized globally.
The big European and Japanese fashion houses have all taken cues from AA trends. All of them.
