The damage: 400 mg per patty
Compared to: 1 ounce of pretzels: 390 mg

Gardenbuger's Black Bean Chipotle Veggie Burger, Amy's All American Veggie Burger and Boca's All American Flame Grilled Burger each has roughly 400 milligrams of sodium per patty. And you always wondered how something that isn't meat could be so tasty ... all you have to do is check the sodium content for your answer. Add a bun (206 milligrams), slice of cheese (368 milligrams) and a packet of mustard (57 milligrams), and you're downing over 1,000 milligrams of sodium.

The damage: 380 mg in 2 Tbsp
Compared to: 1 serving of Wendy's small French fries: 330 mg

Still think your fries aren't salty enough? Maybe it's a good thing those annoying little ketchup packets are so hard to open.

The damage: Up to 440 mg of sodium in a 4-ounce serving
Compared to: 2 bags of Doritos: 420 mg

This is probably the sneakiest source of sodium of all. Even though it's labeled "natural," a lot of the raw chicken you buy at the grocery store is plumped up with a sodium solution that makes the meat juicier -- and heavier, so you pay more. Double-check the labels -- a truly natural chicken won't have a sodium content higher than around 70 milligrams per serving.
