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 Bisphenol A safe in food and drink?

Q: Is bisphenol a safe in food and drink?

Under the app's default Cautious lens, bisphenol a in food and drink rates Swap: the app would put this near the top of your swap plan. 4 sourced concerns count (endocrine, consensus tier; endocrine, consensus tier; suspected carcinogen, emerging tier). This is research with sources, not medical advice.

Food processing1 use researched4 sourced claims

Where it turns up: plastic chemical migrating from food packaging. Detox My Life researched bisphenol a 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 (4)

ConsensusEndocrineconfidence 50%

Dietary exposure to bisphenol A (BPA) is a health concern for consumers across all age groups due to potentially harmful effects on the immune system, as well as reproductive, developmental, and metabolic systems.

Why here: BPA can leach from food contact materials, such as polycarbonate plastics and epoxy resins used in can linings, into food and beverages, leading to dietary exposure.
What would have to be true: Dietary exposure exceeding the tolerable daily intake (TDI) of 0.2 nanograms per kilogram of body weight per day (0.2 ng/kg bw/day).

ConsensusEndocrineconfidence 50%

The U.S. Food and Drug Administration (FDA) maintains that BPA is safe at the current levels occurring in foods, based on its safety assessments of BPA in food packaging.

Why here: BPA is used in food contact materials, such as can linings and polycarbonate plastics, and small amounts may migrate into food and beverages.
What would have to be true: Ingestion of BPA at levels below the FDA's established safe level of 2.25 milligrams per pound (5 mg per kg) of bodyweight per day. Most people are exposed to 0.1-2.2 micrograms per pound (0.2-0.5 micrograms per kg) of bodyweight per day.

EmergingSuspected carcinogenconfidence 50%

Accumulated evidence from rodent studies suggests that early-life BPA exposures may lead to increased susceptibility to mammary and prostate cancer, with some researchers proposing classification as 'probably carcinogenic to humans' (IARC Group 2A).

Why here: Ingestion of BPA from food contact materials can lead to systemic exposure.
What would have to be true: Early-life exposure to BPA, even at low doses.
The other side: The World Health Organization (WHO) concluded in 2010 that there was insufficient evidence to judge the carcinogenic potential of BPA, and a 2021 meta-analysis found 'no association' between BPA and breast cancer. IARC has not yet classified bisphenol A, though an advisory group recommended review.

EmergingEndocrineconfidence 50%

Studies link BPA exposure to adverse effects on the immune system, neuroendocrine processes, reproductive mechanisms, and metabolic diseases, including weight gain, insulin resistance, and type 2 diabetes.

Why here: BPA leaches from food and drink containers into ingested food or liquid, leading to human exposure.
What would have to be true: Low-dose exposure, particularly during early developmental stages, with some studies showing effects at levels significantly lower than regulatory 'safe' limits.

Not researched here

The engine has no dossier for bisphenol a 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.
