In Australia supermarkets certainly advertise fresh fruit and vegetables in multiple forms of media. And not just "we sell vegetables", but "this week Australian grown XXXX are just $Y per kg!"

Australian readers can probably hear that Coles announcer voice in the heads right now.

Does this heuristic only apply if its a standalone advertisement?

That would cut out bananas, mangos, avocados, pistachios, every mainstream meat, eggs, dairy and water (both bottled and tap).
