The post is a bit misleading. The Mc Rib is mostly from a pig but it is not the normal "meat" from the pig. It is processed from the pig innards, tongue, stomach, and other items that no one would normally eat. The process it all with a lot of salt and make it into a log and cut it into Mc Rib pieces. So, if you are saying that only 2% is really regognizable pig meat then you would be correct, otherwise, you are misleading. Either way you are much better off without it.
They changed something a couple decades ago and it doesn't taste the same to me as it did when I was younger. I think they use corn syrup in their sauce rather than real sugar nowadays. I might eat one this year, but that's it. It's just not that addicting to me anymore.
