> And wouldn't noodlesoup be even cheaper, and healtier too?

That would depend on if the crisps were fried in transfats. Otherwise they both end up as a ball of diabetes-causing carb covered in salt.

The point is that stuff like crisps is way cheaper than it should be, making it an option for poor people when stretching their budget. I hope people don't actually eat it for dinner ;) Noodle soup is healthier but still not healthy. Most cheap noodles soups are full of the "wrong" kinds of fats and sugar.
