It sure would take a massive cultural shift for black people to give up a lot of soul food staples since, again, it’s a big part of their culture.

And I have no idea why you think less subsidies would make people who make soul food eat less fried food. They were eating fried food when they had to make it with pig fat and had no choice and they’re still making it now, often still with pig fat. Subsidies are not involved.

I think you need to do a little exploration into soul food and also how important it is. This is a lot bigger than just “we need to stop eating this stuff, it’s unhealthy.”
