Food additives1 use researched6 sourced claims
Where it turns up: antioxidant to prevent rancidity. Detox My Life researched bht 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.

ConsensusIntake guidelineconfidence 100%
The European Food Safety Authority (EFSA) has established an Acceptable Daily Intake (ADI) for BHT (E321) at 0.25 mg/kg body weight per day, concluding that BHT is not of concern with respect to genotoxicity or carcinogenicity.
- Why here
- This claim outlines the regulatory stance and safety assessment by a major European food safety authority regarding BHT ingestion.
- What would have to be true
- Ingestion of BHT as a food additive, with an ADI of 0.25 mg/kg body weight per day.

ConsensusIntake guidelineconfidence 100%
The World Health Organization (WHO) has allocated an Acceptable Daily Intake (ADI) of 0-0.3 mg/kg body weight per day for BHT.
- Why here
- This provides the ADI set by another international regulatory body for BHT ingestion.
- What would have to be true
- Ingestion of BHT as a food additive, with an ADI of 0-0.3 mg/kg body weight per day.
Sources the engine cites:
EmergingSuspected carcinogenconfidence 70%
High-dose animal studies have linked BHT ingestion to the promotion of tumors in the liver, bladder, and lungs, although BHT is not classified as a human carcinogen by IARC.
- Why here
- This claim highlights the potential carcinogenic effects of BHT through ingestion, based on animal research.
- What would have to be true
- Ingestion of BHT at high doses, as used in animal studies.
Sources the engine cites:
EmergingEndocrineconfidence 80%
BHT is a suspected endocrine disruptor, with animal studies linking high-dose exposure to developmental effects and thyroid changes, suggesting interference with hormonal signaling.
- Why here
- The claim directly addresses the potential for BHT to disrupt the endocrine system through ingestion, based on animal studies.
- What would have to be true
- Ingestion of BHT, particularly at high doses, as observed in animal studies.
Sources the engine cites (no regulator, review or study among them):
- 2 web articles (millionmarker.com, btsa.com), linked in the app.
EmergingMetabolicconfidence 80%
High-dose oral studies in rats showed renal and hepatic damage at acute doses of 0.5 to 1.0 g/kg, and subacute exposure at lower doses was linked to liver toxicity.
- Why here
- This claim details specific organ toxicity observed in animals due to BHT ingestion.
- What would have to be true
- Acute oral doses of 0.5 to 1.0 g/kg BHT in rats, or subacute exposure at lower doses.

ConsensusClearedconfidence 100%
BHT is permitted as a food additive in the United States by the FDA, which classifies it as Generally Recognized As Safe (GRAS) when used within specified limitations, such as up to 0.02% of the fat or oil content in most foods, or specific ppm for certain food categories.
- Why here
- This claim directly addresses the regulatory status and permitted use levels of BHT for ingestion in food products.
- What would have to be true
- Ingestion of food products containing BHT at concentrations up to 0.02% of the fat or oil content, or specific ppm (e.g., 50 ppm in dry breakfast cereals, 200 ppm in emulsion stabilizers for shortenings).

Not researched here
The engine has no dossier for bht 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.
