Facts are, if you ground up pigs eyes and covered em in breadcrumbs and flavourings, then marketed them as porky pieces or something, a lot of people would eat them, so long as you don't actually go 'its minced up eyes!'. I imagine 'reclaimed pork offal' would cover it.
Yet I'd hazard a guess it's not BAD for you, just we're grossed out by certain things like eyes and brains.
As for so many of the arguments here, I suggest everyone in the world reads 'Bad Science' by Ben Goldacre, or at least has a roam of his site, if nothing else he called out the screeching harpy, Gillian "I bought my Dr title at Walmart" McKeith, on her wild imagination and sheer fiction about food science.
Now Gillian McKeith was trying to stop fat people eating themselves to death, that's fine, but it destroys all the work if it turns out you've just made it all up.
I believe he was a big part of the 'homeopathic overdose' protest across the UK also, trying to get drugstores to stop selling homeopathic remedies (sorry, I mean small bottles of water), as cures to disorders and diseases, by having thousands of people buy a full pack and consume it in one go.
Essentially, he lives to call out just this kind of shit that gets printed in the press media and given airtime on shitty news shows, and I salute him.
When you read '14% of all child abuse happens on a Monday' stop for a moment...hold off on reacting and THINK. "14%? that's a one in seven chance, that somemthing would happen one day in a week, where's the news or science again?"
A bit off topic, but it pissed me off that some vitamins have to be listed as E number additives, to the point where some people are put off buying things with extra vitamins and minerals in, as they're listed as 'additives' and duh, additives are always bad aren't they?
