What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Is 3-Monochloropropane-1 2-Diol Esters safe in food and drink?

Q: Is 3-monochloropropane-1 2-diol esters safe in food and drink?

Under the app's default Cautious lens, 3-monochloropropane-1 2-diol esters in food and drink rates Swap: the app would put this near the top of your swap plan. 3 sourced concerns count (suspected carcinogen, consensus tier; restricted, consensus tier; metabolic, consensus tier). This is research with sources, not medical advice.

Food processing1 use researched3 sourced claims

Where it turns up: refined vegetable oil processing by-product. Detox My Life researched 3-monochloropropane-1 2-diol esters 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 50%

Upon ingestion, 3-monochloropropane-1,2-diol esters (3-MCPDE) are hydrolyzed in the gastrointestinal tract to release 3-monochloropropane-1,2-diol (3-MCPD), which is classified by the International Agency for Research on Cancer (IARC) as a possible human carcinogen (Group 2B) based on animal studies showing tumor formation.

Why here: 3-MCPDEs are processing contaminants found in refined edible oils and fat-containing foods, and upon ingestion, they are metabolized to 3-MCPD, which is the substance with carcinogenic potential.
What would have to be true: Exposure to 3-MCPDEs occurs through consumption of refined vegetable oils, margarines, baked goods, fried foods, and infant formula; high consumers, especially infants receiving formula, may exceed tolerable daily intake levels.
The other side: The European Food Safety Authority (EFSA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA) have established tolerable daily intake (TDI) and provisional maximum tolerable daily intake (PMTDI) values for 3-MCPD and its esters, indicating levels considered safe for most consumers, though high consumers in younger age groups may exceed these levels.

ConsensusRestrictedconfidence 50%

The European Union has set maximum limits for 3-monochloropropane-1,2-diol esters (3-MCPDE) in refined oils, with specific, stricter limits for infant foods and cereal-based preparations for infants and young children, effective January 1, 2027.

Why here: 3-MCPDEs are contaminants in refined oils used in various food products, including infant formula, and regulatory bodies have established limits to minimize dietary exposure due to potential health risks.
What would have to be true: Consumers are exposed to 3-MCPDE through the ingestion of refined vegetable oils and products made with them, with infants and young children being a particularly vulnerable population due to their higher relative intake.
The other side: These regulations are being implemented to reduce the levels of 3-MCPDE in food products, and the food industry is actively working on mitigation measures to comply with these limits.

ConsensusMetabolicconfidence 50%

Ingestion of 3-monochloropropane-1,2-diol esters (3-MCPDE) can lead to adverse effects on the kidneys, such as renal nephropathy and tubular hyperplasia, and male reproductive organs, including impaired sperm production and testicular atrophy, as observed in rodent studies.

Why here: 3-MCPDEs are hydrolyzed to 3-MCPD in the digestive tract, and this metabolite has been shown to cause kidney and reproductive toxicity in animal studies, which are the basis for establishing safe intake levels.
What would have to be true: Exposure occurs through the consumption of refined vegetable oils and foods containing them, with high intake levels, particularly in infants consuming formula, potentially exceeding the tolerable daily intake (TDI) of 2 µg/kg body weight per day set by EFSA.
The other side: Regulatory bodies like EFSA and JECFA have established tolerable daily intake (TDI) and provisional maximum tolerable daily intake (PMTDI) values for 3-MCPD and its esters, and the food industry is implementing measures to reduce their levels in food products, especially infant formula.

Not researched here

The engine has no dossier for 3-monochloropropane-1 2-diol esters 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.
