Do what makes you comfortable. My take is controversial and risky, but I don't really care.
I think the nitrate nitrite thing is a bit of a food scare and would eat it. Preservatives aren't primal, but some may turn out to be beneficial. There I said it.
The same CW that vilified saturated fats may be in play here. My 85 year old uncle is playing tennis this morning, just like every morning, and he's eaten bacon, sausage, cured Italian cold cuts -- every day of his life since he got off mother's milk. He is so ridiculously healthy for his age, I expect him to live to 100, and Mark Sisson won't be as cut at 85. Dude's built like an NFL running back.
