Watch out if you ever order the Boston Market Creamed Spinach side dish. It comes packed with 280 calories, 23 g of fat, and 580 mg of sodium. It may taste great but bad things do come in this small package. Same goes for McDonald's Cinnamon Melts, featuring 460 calories, 19 g of fat, and 370 mg of sodium.

Ah, Wendy's large fries. Gotta love 'em. Gotta avoid 'em too, unless you like a quick dose of 550 calories, 26 g of fat, and 480 mg of sodium. Steer clear of Chipotle Chips & Guacamole too. Calories: 710. Fat: 37 g. Sodium: 740 mg. Need I say more?
