I pretty much gave up sardines when buying them in bpa-free cans cost almost as much as buying whole salmon (the per pound price). But before that I was eating at least 12 cans per month and I eat lox on a regular basis. I haven't had pickled herring in awhile, so that will be a treat next time I venture out to a grocery store. I like mixing it up a bit. Fish has always been a part of my diet, so Primal just meant eating it a bit more.
One thing you'll never hear me say is, "Damn, there's just too much seafood in my diet."
