Approximately 3.5 years ago, I wrote on this blog about the fundamental fraud of no-nitrate cured products (post #1, post #2). This was the more substantial post on the topic.
By far the best essay I've seen on the topic it is, "Nitrite-free Where Does the Truth End."
The New York Times has just written about the issue; that's great. Now US foodies will get savvy about it.
