If you were *trying* to create nitrosamines from nitrates, high-temperature meat is basically the perfect environment to do so. Plants, by contrast, are pretty terrible.

In case you're curious about the specifics:
Heme iron, when cooked, yields free Fe+2 and Fe+3. These are *pro-oxidants*, and oxidize NO to NO2 (a poisonous compound). This attacks secondary amines in proteins (which meats are rich in) to form nitrosamines. Heme formation of reactive oxygen...

Heme iron (found in meat) also promotes the formation of nitrosamines, as do fats, as does the sort of high temperature cooking that meats usually undergo. Meat is the worst-case scenario.
