FYI, a whole lot of “uncured” meats, at least in the US, are just kind of using loopholes. Often there’s a little asterisk next to the word “uncured”
And if you follow that asterisk to the bottom of the back side of the package or wherever they decided to hide it in small print you’ll see it says something like “contains no added nitrites or nitrates except those naturally occurring in celery powder or other natural ingredients”
And spoiler alert, celery has kind of a lot of nitates and nitrites.
And while there are regulations about how much pure nitrates/nitrites they can add to your food, there’s no regulation on how much celery powder they can add because it’s just considered a “flavoring” ingredient and not a curing agent. “Uncured” bacon or hot dogs or whatever could technically contain far more nitrites than would legally be allowed in their cured counterparts (though in practice I’m sure they’re probably roughly the same amount)
Regardless of if those nitrites are pure or coming from celery powder, it’s the same chemical doing the same thing in your food and body.
Other veggies contain a lot of nitrites/nitrates too, cabbage for example. I’ve occasionally had it happen when I make cabbage rolls in a pressure cooker that despite being totally cooked through the ground beef is still a pretty vibrant red/pink like corned beef because of the nitrites from the cabbage.
I’m not saying this to scare-monger or anything, there are valid health concerns about nitrates and nitrites in general, and of course people like you who have a particular sensitivity to them, and it’s well worth being aware of all of that. That said, I’ve been dabbling in curing my own meats and have a big jar of Prague powder #1 in my pantry which is 6.25% sodium nitrite, so clearly it’s not something that’s particularly high on my own list of concerns. I also intend to try curing my own corned beef at some point with celery juice and other natural sources of nitrites, not because I think it’s any healthier but because it sounds like a fun experiment.
I think possibly the best steak I ever had/made was a cheap chuck steak that I gave a nice long sous vide treatment
There is a whole lot of flavor there, but it can be as tough as shoe leather, but with sous vide it came out as tender as any filet, but way beefier
