Baguettes are not really healthier than chips. The same can be said for sushi (well sushi got some other stuff that's good for you, but let's just think weight loss). They're mostly just carbs.

If Americans had sushi and baguettes they wouldn't be slim like the French and Japanese, they'd eat sushi till they are 110% full (the Japanese aim to not stuff themselves at meals) and then carry around a bag of baguettes for in-between grazing (the French prefer set meals).

They'd also blame everything on their delicious national cuisine, rather than on themselves.
