I noticed this in high school and then again in college. White people, mostly women, are espousing the virtues of health food - fresh veggies and shit. POC are selling Fanta and potato chips. And the way white people talk about POC's heritage foods ... it's a whole long rant that I'm too tired for right now but yes. This is very much a thing. It is one more way the PTB are trying to keep everyone who isn't a rich white guy sick, broke, and stupid.
