Arby’s Mozzarella Sticks

Six battered-and-fried sticks contain 2,530 mg of sodium, more than a day’s worth , and 620 calories. Whole-milk mozzarella isn’t the saltiest cheese around. It contains 178 mg of sodium per 1 ounce, according to CalorieLab.com, versus nearly 272 mg for a Kraft nonfat American single.

“Typically, a lot of salt is added to the breading mixture, which drives up the sodium content of the fried mozzarella sticks,” Kleiner says.

Choose this instead: A serving of three Potato Cakes contains 700 mg of sodium and 340 calories.
