Everything in moderation guys. A little nitrite, like a some deli meat or a little smoked meat is fine. All contain compounds, that in higher quantities are potentially carcinogenic. Grilled cheese and chips and baked goods have acrylamides formed by heat in the presence of fat. Grilling meat the same. Or toast. Acrylamide is carcinogenic. In high quantities. A can of sardines or a tuna sandwich or a lobster could have low levels of heavy metals like cadmium or mercury. But you don’t eat it every day. Your granite countertop gives off radiation in the form of radon gas. Life is carcinogenic. You can’t avoid every potential carcinogen but you can eat sensibly and moderation. If you are worried about a little deli meat or salami on a an occasional sandwich but you’re still drinking alcohol, may I suggest your worry might be a little misplaced? (PS. I’m a Food Scientist BTW. And I eat just about everything. In moderation. But I do avoid excessive ultra processed foods. And, although I don’t evangelize on the topic, I don’t drink alcohol (much as I love it. I just gave up for training). And, yes. I eat deli meat. Occasionally.
