People are missing geography black people were largely enslaved in the southand lived for generations after in the south. Look at southern cuisine. The fact thet so much of traditional black american foods are based around the best you can with poor quality food available to slaves. There's a lot of fat, and frying etc. Cooking techniques used to make poorer quality food tasty.

If im not mistaken the south in general is more obese than other areas. I imagine southern whites are also more lokely to be obese as they were eating alot of thr same food as much if it was you know prepared by blacke people. Even if black people move from yhe south the food culture is born from there.
