CLAIM:

Using aluminium utensils for cooking is dangerous and can cause cancer. The claim suggests that preparing food in aluminium cookware directly exposes people to carcinogenic risks, making it unsafe for everyday use.

FACT:

Aluminium can leach into food, especially when cooking acidic items or using low-quality utensils, but current scientific evidence does not show a clear or consistent link between normal aluminium cookware use and cancer. Health risks are mainly associated with excessive exposure or poor-quality materials, not routine household use.

In a viral reel posted by Instagram handle ‘learnwithshamani’, which has 62.7K followers, a clip from a podcast conversation between Dr Tarang Krishna and Raj Shamani has been widely circulated online. In the video, Dr Tarang shares a list of lifestyle changes viewers should adopt at home, positioning them as immediate health interventions.

Among these recommendations, he urges people to stop using aluminium utensils altogether. Responding to a prompt about the top changes one should make, he says, “First of all, go to the kitchen. Throw away all the aluminium utensils. If you are cooking in aluminium utensils, it is… you are cooking cancer.” He presents this as a direct health risk linked to everyday cooking practices.

The reel has gained over 5.4 million views and around 2,391 shares, sparking concern and debate about the safety of aluminium cookware in Indian kitchens.

Do aluminium utensils cause cancer? What research says

Evidence shows that while aluminium can leach into food, especially under high heat or acidic conditions, there is no strong or consistent evidence linking normal use of aluminium utensils to cancer. The greater concern lies in excessive exposure, poor-quality cookware, or underlying health conditions, rather than routine household cooking practices.

A 2000 study examining aluminium intake in Indian diets found that food itself is a major source of exposure. The researchers noted that “food and water are the major sources of Al ingestion in normal population groups,” and that “significant levels of Al were detected in most of the cooked foods analysed.” The study highlighted that green leafy vegetables and pulse-based dishes such as dal and sambar contributed substantially to daily intake. While it also observed that “use of Al utensils significantly contributes Al to total daily intakes through foods,” it concluded that staples like rice and milk contribute very little, indicating that overall exposure comes from multiple dietary sources—not just cookware.

More recent research has explored not just aluminium, but other metals that may leach from certain types of cookware. A 2017 multi-country study analysing 42 aluminium cookware samples, particularly low-cost, artisanal ones, found that some released harmful metals like lead, cadmium and arsenic during simulated cooking. In some cases, “1 to 1426 micrograms of lead per serving” were detected. The researchers concluded that such cookware “is a significant and previously unrecognised source of exposure to lead and other metals,” especially when made from scrap materials. However, this reflects risks linked to poor-quality or contaminated cookware, rather than standard aluminium utensils in general.

A 2019 review focusing on health impacts noted that aluminium utensils are widely used in countries like India and that concerns stem from their potential to leach into food over time. It explained that only a small fraction - “0.01% to 1% of orally ingested aluminium is absorbed from the gastrointestinal tract” - and is typically excreted by the kidneys in healthy individuals. While some studies have linked high aluminium exposure to conditions such as anaemia, bone disorders and neurological issues, the review emphasised that the risk is more relevant for people with kidney disease, where the body cannot efficiently eliminate the metal.

Another scientific review echoes this cautious but not alarmist stance. It acknowledges that aluminium has “proven noxious impact on the human body” at high exposure levels and notes associations with certain cancers such as bladder and lung cancer in occupational or excessive exposure contexts. At the same time, it clarifies that “short-term use of aluminum pots does not pose a threat to our well-being,” and even long-term use typically does not exceed recommended intake levels for most people. The review advises simple precautions such as avoiding cooking highly acidic foods in aluminium utensils and replacing worn-out cookware over time.

Regulatory agencies also reinforce that everyday exposure is unlikely to be harmful. According to the UK’s public health guidance, “low level exposure from the correct use of products that contain aluminium such as cans, cookware, utensils and food wrappings would not be expected to cause adverse health effects.” It stresses that the impact of any chemical depends on dose, duration and route of exposure.

What experts say

Dr Utkarsh R. Ajgaonkar, DrNB (Surgical Oncology) at TGH Onco-Life Cancer Centre, said that “while excessive aluminium exposure can have health implications, it is not linked to cancer.”

“High levels of aluminium in food are linked to conditions like Alzheimer’s disease and bone-related problems, but not cancer,” he added.

He also noted that the quality of cookware matters, warning that low-grade aluminium utensils may pose greater risks due to increased metal leaching. “As a precaution, opt for safer alternatives like stainless steel utensils,” he advised.
