It turns out those "chicken" nuggets you sometimes order might not have so much chicken after all. Two nuggets examined in a recent study from the American Journal of Medicine were found to have 50 percent or less chicken muscle tissue, with the rest of the snack consisting of fat, blood vessels, nerve, cartilage or pieces of bone, according to Reuters.

It's important to note that for this study the researchers examined one nugget each from two undisclosed national fast food chains. Factoring in the minuscule sample size, no fair conclusions can be drawn about the the true makeup of most chicken nuggets out there.

"What has happened is that some companies have chosen to use an artificial mixture of chicken parts rather than low-fat chicken white meat, batter it up and fry it and still call it chicken," the study's lead author Dr. Richard D. deShazo told Reuters Health.

"It is really a chicken by-product high in calories, salt, sugar and fat that is a very unhealthy choice. Even worse, it tastes great and kids love it and it is marketed to them."
