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.

Where it turns up: prevents mold in baked goods. Detox My Life researched calcium propionate 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.

Sourced concerns (3)

EmergingMetabolicconfidence 80%

Propionate intake is linked in studies to increased production of insulin and glucagon, potentially leading to insulin resistance and an increased risk for obesity and type 2 diabetes.

Why here: Calcium propionate is ingested as a food preservative and is broken down into propionic acid, which can then influence metabolic pathways.
What would have to be true: Consumption of calcium propionate as a food additive in baked goods, dairy products, processed meats, and other foods, with studies investigating doses such as 1g or 1500mg of calcium propionate.

EmergingIrritant · allergenconfidence 80%

In rare cases, sensitive individuals may experience mild adverse effects such as headaches, stomach pain, rashes, bloating, migraines, or diarrhea upon ingestion of calcium propionate.

Why here: These effects are observed in individuals who are allergic or sensitive to the chemical or preservatives in general, following ingestion.
What would have to be true: Consumption of calcium propionate as a food additive, particularly in individuals with sensitivities.
The other side: For the vast majority of consumers, calcium propionate is considered safe and well-tolerated at approved usage levels, and is processed by the body similarly to other naturally occurring fatty acids.

EmergingMetabolicconfidence 70%

Small-scale studies have suggested that daily consumption of calcium propionate in bread may be associated with irritability, restlessness, poor attention, and sleep issues in children.

Why here: Calcium propionate is ingested as a food additive in products commonly consumed by children, such as bread.
What would have to be true: Daily consumption of calcium propionate-containing bread.
The other side: However, there is not enough evidence to conclusively back these claims, and subsequent larger-scale studies have failed to consistently replicate these findings; regulators generally agree that calcium propionate does not cause ADHD or generalized hyperactivity in children.

Not researched here

The engine has no dossier for calcium propionate 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.
