Several popular fast-food chains are announcing new menu items. Taco Bell has a new Chicken Chipotle Melt. McDonald's is putting a celebrity-endorsed meal onto the menu for the first time since 1992. And whether you agree with pineapple on pizza or not, Papa John's recently announced the addition of the Super Hawaiian Pizza to its lineup.Wendy's is taking part in the trend, too, with the new Pretzel Bacon Pub Cheeseburger. Yes, pretzel buns are back. But this time there is "a quarter pound of fresh, never frozen beef topped with Muenster cheese, three strips of Applewood smoked bacon, smoky honey mustard, warm beer cheese sauce, crispy fried onions, and pickles. Salty and savory with the perfect balance of sweetness, one might say it is like flavor harmony wrapped in love."While the description the restaurant provides in a new statement sounds pretty appetizing, the nutrition information paints a different picture. One single burger (with no fries or a drink) has 730 calories. This isn't as bad as other specialties on the menu, like a single Baconator, which has 960.RELATED: The Best and Worst menu items at Wendy'sCalories aren't the only things that count, though. The burger also has almost half of the amount of sodium you're supposed to have in a day. The CDC says Americans should consume no more than 2,300 mg each day. Just one Pretzel Bacon Pub Cheeseburger contains 1,070 mg. And worst of all, it also has 44 g of fat. A healthy fat intake per day according to the Cleveland Clinic is exactly 44 g.These stats are only for the single, too. Order a double and you're looking at 1,180 calories, 79 g of fat, and 1,610 mg of sodium. Triple it and the totals come out to a whopping 1,520 calories, 106 g of fat, and 1,910 mg of sodium. Add a small fry to any of these and add 270 calories, 13 g of fat, and 210 mg of sodium."Like we did with Spicy Nuggets, we've been watching and listening as customers have been craving for us to bring Pretzel back," says Carl Loredo, the chief marketing officer for the company. "We married the fervor for our former pretzel bun with the increased love for gastropub-inspired flavors and created a cheeseburger that is, in a word, unforgettable."Unforgettable it may be, but it's definitely one to skip or split the next time you head to Wendy's.STAY INFORMED: Sign up for our newsletter to get the latest fast food restaurant news delivered straight to your inbox.
