THE SALTIEST FOOD IN AMERICA
P.F. Chang’s Hot and Sour Soup Bowl
6,878 mg sodium
336 calories
12 g fat (2 g saturated)

Sodium Equivalent: 208 saltine crackers

P.F. Chang's has published their nutrition facts for years without providing sodium counts for basic menu items, which was cause for concern and—as it turns out—justified suspicion. Chinese food tends to run high on the sodium spectrum because of its reliance on viscous stir-fry sauces and salt-laden condiments like soy sauce. But this an unfathomable amount of salt to pack into one 336-calorie bowl of soup. The sad truth is that unless you stick to vegetable sides and small servings of a select few entrees (Crispy Honey Chicken, Orange Peel Beef, Lemon Scallops), you’re all but guaranteed to absorb one or more day’s worth of sodium in a single sitting at P.F. Chang’s.

Oops. Well, okay. But it's darn good soup.

On a side note, if you haven't seen Eat This, Not That
it's quite good! I own a copy, and find myself constantly staggered by the statistics.
