I think the nitrate/nitrite issue depends. I know a lot of people that do just fine eating bacon. Maybe they go overboard when they first find out it's not banned and eat a pound a day, but tons of ANY single food gets old and you eventually start foraging for other foods to add in.
I can't eat it. You can tell me all day that there are more nitrites in my spit, but I still get a migraine when I eat foods with sodium nitrite and I don't just swallowing my spit. That aso includes meat processed with celery salt, celery seed and celery juice, which are the same chemically but just sound a little less toxic. In fact, many times there are higher levels of sodium nitrite in foods where they use celery seed/salt/juice than if they just straight up use the commercial version. Found that on out the hard way.
If it's not a problem for you, I don't know if it will eventually be a problem or not. Am I overly sensitive to it or am I the canary in the coalmine? I know I'm definitely not the only one that has a problem with it, but I can't honestly say if it has a hidden effect on others that don't feel the pain, or if it's only a problem for those of us that do. I also have the same problem (migraine) with wine, both red and white, and I can't see that being detrimental to the average guy unless they're abusing it.
