> It's much more nuanced than that.

> Bread and water is prisoner food, but avocado toast and cream-cheese bagels at the corner bodega are considered mid-to-upper-class fare.

That's not an example of nuance. An expensive fruit and a heavily-processed cheese are much higher-grade food than bread is.

> Pasta (also wheat) can range from kraft mac-and-cheese (poor-coded) to hand-made pasta with pesto sauce.

Same thing; cheese is a high-grade food, and even pesto is chock full of fat.

> Even though rice is the staple food of Japan, I'd actually argue that instant ramen is much more poor-coded these days than even ochazuke.

And this is a statement that even the poorest people in Japan aren't so poor that they have to subsist on rice. There's no question about which of instant ramen or ochazuke is a better meal. Instant ramen comes with tons of spices, fats, salt, some vegetables, and even a little meat.
