I'm living with several allergies and -amine sensitivities, it took me some time to figure out that foods with nitrates/ites were exacerbating the problem. I've also read in many places that nitrates/ites are histamine triggers.

The problem I find in both of those articles is that there are far too many maybes and not enough definite facts... the fertilizer worker bit is a good example - I'm sure they weren't eating the fertilizer, how could a cancer or general health link be made at all?. I also wonder exactly who funded the few studies cited... since funding pretty much dictates results.

All I know is that the longer I keep chemicals and processed junk out of my diet, the better I feel. It's not that hard (...OK, it is messy) to make fresh sausage
