Well, that brings nothing new to the table. We've known that for a very long time. But, of course, that story will always have its shocking potential each time it comes out.
Oh, and "100% chicken breast meat" doesn't tell us anything. Ever wondered why your burgers and your nuggets tasted so good? It's because of their high fat content. Otherwise your fast food would taste unbelievably dry.
And no, food companies aren't lying; the fat is certainly part of a chicken's breast -- in fact, there's far more fat in the chicken than there is actual muscle. And in the end, there's nothing fundamentally wrong with that; it's all up to the customer to keep his meals balanced.
Now, another thing the 100% slogan doesn't tell us about is the provenance of the meat. Most often, the meat you'll be consuming will have come from several different chickens -- all ground up together in the same nugget. And those animals could have come from anywhere; that might very well be some Polish-South American chicken blend in your plate... It might seem cruel to us, but that's the reality of the industry.
One last thing: I'd wish all food companies would finally abandon the "home-cooked, grandma-style" imagery they seem to plaster on every single one of their products. If anything is a deliberate lie, that is. Are you thinking of the benevolent family cooking in a wooden stove next to their farm? Forget about it; there's no way they could produce food in such gargantuan quantities. Instead, think of bleached-white, sterile assembly lines in which all your food is prepared and tested before being sent out. And there's nothing inherently wrong with that; when it's done correctly, it's the safest way to mass-produce products of decent quality. What is wrong, however, is the intentional deception these companies practice upon consumers. It's all studied, all worked out with minutia; it's designed for profit, and little else.
