Pizza isn't really/doesn't have to be that unhealthy. Fast food takeaway pizza is of course, but 'pizza' is redundant in that.
Pretty much all that makes a homemade or otherwise decent pizza less healthy than a sandwich is the amount of it one typically eats in a sitting. Or of course if you for some reason pile unhealthy stuff high on your pizzas, but stuff your sandwiches with the height of nutrition. But I assume that would be uncommon.
It's just marketing, I don't see what globalisation particularly has to do with it. Capitalism perhaps, but only to the (debatable) extent that it's responsible for marketing.
You don't see what being connected as a whole (world) has to do with creating social calendar dates? Really?
These things are figments of marketing imagination. They spread through people, not TV or ads. Albeit they start that way. You can throw $$$ at making the 1st of September world Tie day, but it's up to the people to make it stick. Which is becoming increasingly easy as we become a whole connected people.
Sales (lower priced periods) are marketing. "National ___ day" is way more than that.

Well firstly I meant economic globalisation, I was thinking in terms of trade; it seems it has broader/other usages too that I didn't realise. Secondly I'd point to days like Mothering Sunday/Mothers' Day which has a slew of different dates throughout the connected world (even the countries where it's a wholly secular marketing creation can't agree):

Did you mean not? Otherwise we're in agreement.

They don't need to stick, very few do, you hear for the first time about world tie day in late August, maybe get persuaded to buy a wacky new tie, and then forget all about it - or at least when it is - again.
