I eat pepperoni all the time and dont mind. I have had nitrite free pepperoni Applegate farms brand. They all have sugar in some form. I get whatever the supermarket has around. I look for one with as little junk as possible but they sometimes only have one or 2 brands.

I usually drink lots of water and from what I read about nitrites I am not too worried. I am more concerned about aflatoxin in peanuts.
