In Britain certain foods are associated with things like foreign travel that are associated with wealth. No, we shouldn't put things in boxes and say certain people can't eat certain foods, but we should acknowledge that different foods have different significance depending on where you are and also where you come from
I disagree about certain foods being associated with expensive foreign travel available only to the well off, for UK citizens at least, more the wonderfully diverse cultures in many areas that leads to availability of different foods.
In many areas of the UK, you can access food from all over the world on your doorstep, so we can all try all sorts of foods. I've been to a handful of European countries and Egypt, but that's not stopped me being able to try food from dozens of different countries, both in restaurants and takeaways and by cooking the recipes found on the internet.
