"I can still tell if they're food," Astrid says confidently.

It turns out she can't tell reliably through packaging - looking at a can or a sealed bag often leaves her unsure - but she okays virtually everything in the produce section and most of the grains and legumes and spices in the bulk aisle when given examples of them without packaging in the way. Pasta is fine except egg noodles. Vegan chocolate is okay; milk chocolate isn't. No meat, no fish, no dairy. Juice is fine, all kinds.
