The shocking truth behind Costco's $5 rotisserie chicken

No trip to Costco is complete without eating your way through all the delicious samples and walking out with the retail chain's signature rotisserie chicken in hand.

With rotisserie chicken so succulent and savory, it's no surprise that it's a favorite for most people.

But why is it seemingly so addictive?

Well, Dr. Oz wanted to find out and teamed up with food journalist Mark Schatzker to do so. Schatzker revealed on the show that rotisserie chicken is often processed, meaning the bird is "pre-seasoned in factories" and then shipped to supermarkets where "an employee can put it on the skewer and cook it."

The tender meat often contains several ingredients including sugar and salt -- even going so far to compare it a potato chip. In addition, the skin is flavored with MSG, sugar and other natural flavors. This combination helps explain why we can't have enough of the chicken.

However, despite exposing some truths about this dinner table favorite, Dr. Oz Says, that it may be “ one of the healthiest processed foods out there ... and taking off the skin to keep it healthier.”

So go ahead, grab another bite -- or two!
