That site wants me to allow like 30 script URLs so can't see the video and don't feel like screwing with that, but clearly they will only be allowed to talk about the good and not the bad. If they were allowed to talk or mention specific brands then they probably got the permission based on some conditions such as making sure it's positive.
Have you ever seen the farms these animals come from? Their meat is pretty much "processed" before they're even killed. Steroids, antibiotics, and lot of other crap is force fed to them, they can't move, they shit on each other etc, it's far from healthy meat even before they're even slaughtered and then have any extra crap injected into it. You are what you eat, that applies to what your food eats too.
It's a pretty well known and established fact that fast food and processed food is not good for your health, seems odd to try to dispute that.
