Paleo ingredients in Brussels?

Hi, I'm one of those odd people who like to eat (more or less) paleo. That's fine in London, but I'm struggling a bit here. So far I've had no luck finding things like coconut oil, grapeseed oil, almond or coconut flour. Does anyone know if these things are available over here and where?

Also, are there any other paleo eaters/ wannabes? It would be good to find someone who actually knows what I'm talking about!

Cheers,
Mark
