I've been having Traditional Danish sausage and cheese for lunch for days, since my sisters brought some with them. It's delish to a Dane, but man, I'd almost forgotten how fatty it is. I feel so heavy after eating.
But I guess most "traditional" foods are not exactly what people would call Health Food these days. I once had a "traditional English" lunch in a restaurant, lots of bacon and sausage, positively swimming in fat. I nearly couldn't stand up after that meal!
I suppose it's connected to most people having physical work in the olden days, whereas the most we lift these days is the computer mouse. If you work hard in the fields or such all day long, it's more desirable to get a 3,000-chalorie meal. But we still often want the heavy meals, 'cuz they kick off the ol' brain pleasure centers.
