Is Tin safe in food and drink?
Food processing3 uses researched7 sourced claims
Where it turns up: metal migration from cans, cookware. Detox My Life researched tin under 3 different uses, because the same substance means something different in each. 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.
Level by use and lens
Mainstream shows consensus claims only; Cautious adds emerging research; Based adds fringe claims, labelled as such. The last column counts, under Cautious, the sourced concerns, the findings in its favour and the fringe claims Based would add.
Safer swaps: the app's swap catalog covers the products this turns up in: Non-stick pan. Alternatives are always types, never brands.
Eaten or drunk Swap
Under the default Cautious lens tin in food and drink rates Swap: the app would put this near the top of your swap plan. Mainstream (consensus only) rates it Watch; Based (adds the fringe) rates it Swap. Researched 2026-09-03.
Sourced concerns (3)
ConsensusIrritant · allergenconfidence 90%
Ingestion of high amounts of inorganic tin, typically above 200 mg/kg in food, can cause acute gastrointestinal effects such as nausea, vomiting, diarrhea, and stomachaches.
- Why here
- Tin can leach into food from unlacquered tin cans, especially with acidic foods like fruits and pickled vegetables, leading to elevated concentrations in ingested food.
- What would have to be true
- Ingestion of food containing inorganic tin at concentrations of 200 mg/kg or higher; doses ranging from 250 to 1,000 mg tin/kg body weight have been associated with effects in research studies. The UK Food Standards Agency proposed upper limits of 200 mg/kg for tin in canned food. The Provisional Tolerable Weekly Intake (PTWI) for tin is 14 mg/kg body weight.
- The other side
- None.

ConsensusMetabolicconfidence 90%
Ingestion of large amounts of inorganic tin can interfere with iron and copper metabolism, and in severe cases, may lead to anemia, and liver and kidney problems.
- Why here
- Tin can be ingested through contaminated food, particularly from unlacquered tin cans, leading to systemic exposure.
- What would have to be true
- Ingestion of large amounts of inorganic tin compounds in research studies has caused stomachaches, anemia, and liver and kidney problems in humans. Animal studies show similar effects.
- The other side
- None.
Sources the engine cites (no regulator, review or study among them):
- 1 web article (Wikipedia), linked in the app.
EmergingEndocrineconfidence 70%
Animal studies suggest that high levels of tributyltin oxide, a type of organotin, can affect endocrine glands, upsetting hormone levels in the pituitary, gonad, and thyroid glands.
- Why here
- Organotin compounds can be ingested through food and beverages, potentially leading to systemic exposure and endocrine disruption.
- What would have to be true
- High levels of tributyltin oxide in animal studies.
- The other side
- None.

In the home (dust) Watch
Under the default Cautious lens tin in household dust rates Watch: worth watching; the app would list a cleaner alternative type. Mainstream (consensus only) rates it Low; Based (adds the fringe) rates it Watch. Researched 2026-09-11.
Sourced concerns (3)
ConsensusEnvironmentalconfidence 100%
Organotin compounds can enter the environment by leaching from consumer products and from the disposal of products containing organotin compounds in landfills, leading to their partitioning in soils and sediments and accumulation in aquatic organisms and plants.
- Why here
- Household products containing organotin compounds, such as plastics and silicon-coated baking parchment paper, contribute to environmental release through leaching during use and disposal.
- What would have to be true
- Environmental release from household products containing organotin compounds through leaching and disposal.
- The other side
- Tin, particularly in its metallic form and inorganic compounds, is widely recognized as a sustainable and highly recyclable material, with tin packaging often promoted as an environmentally friendly alternative to other materials.

EmergingEndocrineconfidence 80%
Some organotin compounds, found in consumer products and food packaging, have been linked in animal studies to endocrine and immune system effects.
- Why here
- Organotin compounds are used as stabilizers in plastics and in food packaging, leading to potential exposure through contact with or ingestion of these household items.
- What would have to be true
- Contact with or ingestion of organotin compounds from consumer products, with effects primarily observed in animal studies.
- The other side
- Human data on endocrine and immune effects from organotin compounds is still emerging, and these effects have not been definitively established in people.

EmergingMetabolicconfidence 90%
Ingestion of large amounts of inorganic tin from household sources, such as unlacquered tin-lined cans, can lead to gastrointestinal issues like stomachaches, nausea, vomiting, and diarrhea, as well as anemia and liver and kidney problems.
- Why here
- Tin is used as a coating in food cans, and inorganic tin can leach into food, particularly acidic foods or when food is stored in opened, unlacquered cans, leading to dietary exposure within the household.
- What would have to be true
- Ingestion of inorganic tin at high levels, such as 250-1,000 mg tin/kg body weight, or from unlacquered tin-lined cans where concentrations can reach up to 100 ppm.
- The other side
- Most modern tin-lined cans used for food are lacquered, which significantly reduces the leaching of tin into food. Inorganic tin compounds are generally considered to have low toxicity due to poor gastrointestinal absorption and rapid excretion from the body at typical exposure levels.

Not researched here
The engine has no dossier for tin when cooked with heat, in cold food, as a finishing ingredient, on skin (left on) 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.
