As long as you don't eat or drink crap every meal, it's meaningless. Math: 21 meals per week. 2 bad meals. Great percentage. The body wants to be resilient and it is as long as you play nice.
In my many years on this planet, I've learned that eating poorly, on occasion, means very little. I think, based on observation, that you really have to tank it, and actively pursue it, I mean spend all your effort toward poor eating, to get screwed up physically. It's a daily/hourly effort.
Throw in a handful of push ups and a some brisk walks and it's easy to stay healthy (if it's your thing) if you eat properly a lot more often than not.
I can't say whether a revered institution such as the McRib is gross or not, but it's a possibility. I'd like to think it will be this tender piece of heaven. In any case, I'm now tempted, more than ever, to try one. Worst case scenario? I point at it and shout, "NO! Just NO!" and toss that puppy into the bin. I highly doubt it but it could happen. But the thing is, the people in charge already know most people like it, by testing, before it ever hits the restaurants.
As I said in an earlier post, cheeseburgers are (or used to be) too good not to order so I'm not at all sure what will happen when I walk up to that counter.
I'm guessing the meat is pieces collected from places on the animal that no one else wants or it's a byproduct . That's not a jab, it's innovation. Besides, I'm already eating the muscle of animals, using its bone marrow and drinking it's blood. I also take solace that people have been eating tongues and doing interesting things with intestines forever.
I'm not partial, however, to the rodents and whatnot that get added (inadvertently) to the mix but it is currently part of the deal unless I decide to DIY.
This thread has been very fun.
