The Unhealthiest Fast-Food Sandwiches In America Slideshow

It looks just like a normal turkey sandwich, but somehow Arby's manages to load it up with more than a day's recommended allowance of sodium. Turkey is usually considered a healthy protein option because it's leaner than red meat, but when it's paired with bacon and ranch, all of those savings are negated.

Not many sandwiches break 1,000 calories, but BK's Double-Bacon King manages to surpass that mark with some calories to spare. At 1,040 calories, 1,900 milligrams of sodium, and a staggering 69 grams of total fat this burger is an absolute diet demolisher. Although it does pack 57 grams of protein, it manages to only provide one measly gram of fiber.

In 2008, Domino's introduced a line of oven-baked sandwiches that have managed to remain on their menu ever since. But these sandwiches fall victim to the same nutritional pitfalls as Domino's other offerings — lots of fat, lots of salt, no vegetables. The Buffalo chicken sandwich is the least healthy of the bunch, sitting at 840 calories and containing over 2,500 milligrams of salt, more than a person is supposed to eat in an entire day.

Good god... Routinely eating one of these portable beef buffets is the perfect way to frustrate your doctor. Just check out this state line: 1,340 calories, 96 grams of total fat (147 percent RDA), 34 grams of saturated fat (170 percent RDA), and 3,130 milligrams of sodium (130 percent RDA). In addition to 10.5 ounces of beef, this sandwich comes with four strips of bacon, three slices of American cheese, and a whole bunch of mayonnaise. Hardee's has released a variety of questionable menu items, such as a burger that tastes like it's topped with moonshine, but this is probably the most egregious.

Everyone loves brunch, and one ubiquitous menu staple is the breakfast burger, which usually comes topped with a fried egg and a couple strips of bacon. Jack in the Box wanted to recreate this popular combination, but sadly, in their desire to create something beautiful, they've created a breakfast burger abomination. The sandwich is served on a croissant with cheese, hickory-smoked bacon, a fried egg, a beef patty, and a topping of "real" mayonnaise. The sandwich is 770 calories, and provides a full day's worth of saturated fat.

This beast of a sandwich is one of McDonald's most caloric, and hits two of the most important dietary pressure points: half a day's recommended daily allowance of fat and 75 percent of a day's recommended allowance of sodium. The barbecue sauce is so sweet that the sandwich even contains 18 grams of sugar — almost half the amount in a can of Coca-Cola.

Panera Bread is perceived as the health(ier) fast-food option, and while they do incorporate a wider range of vegetables and minimally processed ingredients into their menu items, they still offer up some dastardly options like the steak and white cheddar panini. The ingredients, which include seared steak, pickled red onions, white Cheddar, and horseradish sauce, aren't particularly offensive, but when they're all loaded on a hoagie roll, this sandwich nears the 1,000 calorie mark and contains more than 50 percent of a day's recommended allowance of sodium.

Sonic calls it, "the ultimate burgwich," but this sandwich is more like the ultimate mistake. While the sandwich's fixin's aren't necessarily worse than other fast-food burgers, serving it between two thick slices of Texas Toast bumps up the calorie and sodium content. If you're craving a burger, you're better off sticking with one that's on a regular burger bun.

Subway is supposed to be one of the healthiest fast-food chains in America, but despite offering unlimited vegetable toppings for all of their subs, their chicken and bacon ranch melt is one of the most caloric items on this list. The sandwich is straightforward — seasoned white meat chicken, bacon, Monterey Cheddar cheese, and vegetables — but somehow this combination on a foot-long sub equals 1,220 calories and 2,580 milligrams of sodium.

This Wendy's burger is layered with three quarter-pound patties, and is probably pretty difficult to get your mouth around. With 2,000 milligrams of sodium, 72 grams of fat, four grams of transfat, and 1,090 calories, this is truly a dietitian's nightmare. Curious about Wendy's? Here are 20 things you didn't know about the fast-food chain.
