Does a party require food (or snacks)?

So I am Asian, my husband is black. In the Asian culture every type of party (weddings, birthday, graduations, baby showers) will have food, snacks, whatever something to eat. The biggest fear an Asian hostess has is running out of food at their party. My husband says that parties do not have to have any type of food, and I think that they do because of how I was raised. Lol. I'd like to get some opinions.
