i'm not surprised, really... but there is lots of water in cells so i don't know what they count as "meat" and what they count as "50% water." when i make burgers i cut up veggies and mix them in, as well as a bread and boiled milk mixture to absorb moisture so they don't dry out while cooking. and parasites? thats why you cook meat, because there's bacteria and parasites in it, ESPECIALLY ground beef. cod and other types of fish have worms that are naturally occuring in them. if you eat cod, you have eaten cooked worms, they are bottom dwellers, this is just reality.
if you buy ground beef in a grocery store, a large part of it is connective tissue as well. all muscles have silverskin and tendons that go right into the minces because it looks ugly on roasts and steaks. and that's if you happen to get a batch made out of in store trimmings. most of the ground beef gets shipped already ground up from factories. it's green but mixing it so that oxygen gets at the myoglobin in the meat turns it red again. i have no doubt there is ground up bone, eyeballs, god only knows what in there.
the fact is, it's probably good for you to eat that stuff (not the fat and not fast food burgers, but the ground up bone and eyeballs and stuff) and if you didn't eat it there would be so much waste that red meat would become too expensive to eat. the price of steaks is offset by the fact that you can put (almost) anything in the minces. as well, in the days that pilgrims arrived here, they ate /everything/ on an animal, including the eyeballs and the brain, and i promise you that we still do today (especially in hot dogs). and the reason there's no parasites in hot dogs is they are already cooked. they are cured in salt and sodium nitrate which kills the bacteria the same way cooking does.
aside from preservatives and lots of fat, the fast food burgers probably aren't that horrific. they're bad and i don't eat them, but the picture painted in that interview is grossly exaggerated.
all the same, i grind up a nice shoulder when i want burgers, i make my own bacon, hot dogs, sausages and can tell you exactly what's in all of them. and i dont eat cod!
