The meat content in a nugget was discovered to contain less than half of a chicken nugget. Ground up chicken fat, blood vessels, bones and skin reportedly made up the rest. This was the result of the study published in the American Journal of Medicine. While the authors of the study did not mention the fast food chains they had bought the chicken nuggets for their research, they said these were made mostly of fat and that the name was a misnomer.

The Daily Dose, a Boston Globe blog, compared the calorie content of four pieces of chicken nuggets from various fast food chains. It reported that McDonald's Chicken McNuggets and Burger King Chicken Nuggets contained 190 calories. A four-piece serving from Wendy's contained 180 calories while Popeye's Chicken Tenders only had 153 calories. Kentucky Fried Chicken Original Recipe Bites, meanwhile, only had 132 calories.

Meanwhile, McDonald's Corp posted increased sales for the past 13 months for the period ending in August this year. The 1.9% increase topped analysts' estimates of a 0.3% increase for the period. For the second quarter this year, McDonald's posted revenues of USD 7.1 billion, representing an increase of 2.4% from the results in the second quarter of last year.
