"Sodium Nitrate aka Sodium Nitrite" - From what I remember of organic chemistry class, nitrites and nitrates aren't the same thing. But maybe they can so easily be converted to one another enough so that they can be treated as the same thing?

"BHA and BHT" - I've actually heard a theory that these two are healthy. I don't eat them myself, but I do know of people who eat them as supplements, because they're powerful anti-oxidants and may explain why people in the US get so little stomach cancer compared with other areas (because we use more of these than other countries). They're even being investigated as treatments for AIDS, last I heard.

I agree that the rest of them should be avoided though.
