Healthier processed meats swaps?

With continued data on carcinogens I’m working to understand if it’s the nitrates, cured, sodium, or what.

Unfortunately both my boys LOVE processed meats… sausage, bacon, ham, deli turkey…

Is it specific key words I can look for on a package? Certain brands?

Should I start cooking my own turkey breasts and get a deli slicer? lol
