Food processing1 use researched1 sourced claims
Where it turns up: formed in cured meats, some foods. Detox My Life researched n-nitrosodimethylamine under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

ConsensusSuspected carcinogenconfidence 100%
Ingestion of n-nitrosodimethylamine (NDMA) is classified as probably carcinogenic to humans (IARC Group 2A), based on sufficient evidence from animal studies showing it induces tumors in various organs, and similarities in its metabolism by human and rodent tissues.
- Why here
- N-nitrosodimethylamine can be present as a contaminant in various foods and beverages, can be formed during food processing (e.g., curing, smoking), and can also be generated endogenously in the human digestive tract after ingesting precursors. It has also been found in certain oral medications.
- What would have to be true
- Exposure occurs through consumption of contaminated foods such as cured meats, smoked fish, beer, and cheese; drinking water (with an EPA maximal permissible concentration of 7 ng/L); and certain pharmaceutical products (with an FDA maximum daily exposure level of 96 ng/day).

Not researched here
The engine has no dossier for n-nitrosodimethylamine when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.
This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.
Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
