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

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.
