Re: "uncured" is really also cured, but using celery powder which is a source of naturally occurring nitrates, vs "industrially extracted nitrites/nitrates". The result being the same, the same substance used to prevent spoilage. Incidentally Celery is also high in oxalates, so if you tend to accumulate those (kidney stones) you might be better off with actually "cured" products in comparison with "uncured"
