In Indian households, using plastic containers for food storage and reheating packaged food is a common practice, whether it’s carrying home-cooked meals to work or heating leftovers in the microwave. However, what seems like a harmless convenience may carry significant health risks. 

Research shows that heating food in plastic containers leads to the release of harmful chemicals such as Bisphenol A (BPA) and phthalates into our food. These chemicals, which are used to make plastic flexible and durable, can migrate into food when exposed to heat. Studies have revealed that 93% of people globally have traces of BPA in their bodies, and India is no exception, as plastic use has become deeply ingrained in daily life.

In India, the rising dependence on plastic for takeaways, packaged food, and even home storage has increased the potential for chemical contamination. Whether reheating food in microwaves or placing hot food directly into plastic containers, the risk of chemical migration grows with heat. 

A study published in Environmental Health Perspectives highlighted that plastics with recycling codes #3 (PVC), #6 (polystyrene), and #7 (other) are particularly prone to releasing toxic chemicals when heated. Even plastics labelled “microwave-safe” aren’t foolproof, as prolonged exposure to heat degrades the plastic over time, releasing harmful substances into the food—a concern in India, where microwaving leftovers is an everyday routine.

How Chemicals From Plastic Impact Health? 

India, with its diverse culinary habits, often involves reheating food. The chemicals released from plastic containers, such as BPA and phthalates, have been linked to serious health concerns. These chemicals act as endocrine disruptors, meaning they interfere with the body’s hormonal balance. 

Dr Shanna Swan, a global expert in environmental health, warns that this disruption can lead to conditions like polycystic ovary syndrome (PCOS) in women and decreased sperm quality in men. With reproductive health already a concern for many Indians, especially with rising infertility rates in urban areas, these chemicals pose an additional risk.

The effects of chemical contamination don’t end there. Research has connected BPA exposure to hormone-sensitive cancers like breast and prostate cancer, both of which are prevalent in India. As Dr Swan mentions, small, repeated doses of these chemicals over time can accumulate in the body, leading to severe health conditions. 

Additionally, the Indian Council of Medical Research (ICMR) has been investigating the links between BPA exposure and metabolic disorders like Type 2 diabetes and obesity—both of which are on the rise in India. With fast food and packaged meals becoming increasingly common in Indian urban areas, the country faces unique challenges in addressing the health impacts of plastic contamination.

Experts Warn Against Plastic Use In Reheating

Indian health experts and doctors are increasingly warning against reheating food in plastic containers. Dr Rajesh Kumar, a public health specialist in India, notes that while the convenience of plastic is undeniable, the long-term health effects are deeply concerning.

We see many patients with hormonal imbalances, especially women with PCOS or irregular menstrual cycles, and BPA exposure is one of the contributing factors,” he says.

Dr Kumar’s warnings echo the sentiments of international experts like Dr Leonardo Trasande, who highlights the dangers posed to children, whose developing bodies are particularly vulnerable to hormone-disrupting chemicals like BPA and phthalates.

In India, the awareness of these risks is still relatively low. A survey conducted by the Indian Academy of Pediatrics found that 95% of doctors recommend avoiding plastic containers for reheating baby food, yet 85% of parents were unaware of the risks.

With the widespread use of plastic in everything from dabbas to takeout containers, public health campaigns are urgently needed to educate the masses about the dangers of reheating food in plastic. Experts suggest that opting for alternatives such as glass or stainless steel containers could drastically reduce the risks.

Alarming Statistics On Plastic Contamination

A growing number of studies are finding that the chemicals from food packaging and plastic storage containers are making their way into human bodies at alarming rates.

A global study published in the Journal of Exposure Science and Environmental Epidemiology revealed the presence of over 3,600 chemicals from food packaging materials in human bodies, including common ones like BPA and PFAs (per- and poly-fluoroalkyl substances), both of which have been found in Indian bodies as well.

According to the Food Safety and Standards Authority of India (FSSAI), some of these chemicals, such as BPA, have already been banned in baby bottles, yet they continue to leach into food through packaging and plastic containers used in daily life.

A significant portion of India’s urban population is exposed to these chemicals through the frequent consumption of packaged and ready-to-eat foods, especially as more people shift to nuclear family structures and adopt more urbanized lifestyles.

Traces of PFAs, often referred to as “forever chemicals” because they do not degrade easily, have been found in Indian soil and water supplies, indicating widespread contamination.

Given India’s rapid industrialization, researchers like Dr Birgit Geueke from the Food Packaging Forum Foundation are calling for more stringent regulations on plastic use, particularly in food packaging.

“Forever Chemicals” In India

PFAs, or “forever chemicals,” have become a major environmental and health concern in India, especially as the country grapples with industrial pollution and increasing reliance on plastic packaging. These chemicals, known for their water- and grease-resistant properties, are used in everything from food wrappers to nonstick cookware.

In India, where street food culture thrives and packaged foods are gaining popularity, these chemicals pose a unique threat. The Environmental Protection Agency (EPA) has linked PFAs to severe health issues, including cancer, liver damage, and developmental delays in children—ailments that are becoming more prevalent in India’s urban centres.

PFAs accumulate in the body over time, and while a single exposure might not seem alarming, the repeated contact through food packaging, cooking utensils, and everyday products raises the stakes significantly. India’s regulatory bodies, such as the FSSAI, are slowly recognizing the need for stricter measures, but enforcement remains a challenge.

For Indian consumers, it’s becoming increasingly important to limit contact with PFAs by avoiding plastic-wrapped foods and opting for traditional cooking methods that minimize chemical exposure.

Safer Reheating Alternatives For Indian Kitchens

In India, where reheating food is an integral part of daily life, especially with the culture of packed lunches and home-cooked meals, switching to safer alternatives is critical. Experts recommend replacing plastic containers with glass or stainless steel for reheating. Unlike plastic, these materials don’t degrade when exposed to heat and are free from harmful chemicals. 

Glass containers, in particular, are widely available and a safer alternative for microwaving. The FSSAI also advises against reheating food in plastic, emphasizing the benefits of using traditional materials like stainless steel, which have long been part of Indian kitchens.

For many Indian households, the shift might require an initial investment, but the long-term health benefits far outweigh the convenience of plastic. Even when using reusable plastic containers, it’s crucial to avoid placing hot food directly in them or reheating food multiple times in plastic.

As more Indian families become aware of the health risks, there’s hope that practices will gradually change, shifting toward healthier, safer alternatives for food storage and reheating.

A Sustainable And Healthier Indian Future

With increasing awareness about the dangers of plastic, Indian households are starting to explore alternatives that benefit both health and the environment.

By switching to reusable, eco-friendly options like glass, ceramic, and stainless steel, families can not only reduce their exposure to harmful chemicals but also contribute to environmental sustainability. India’s growing urban population is contributing significantly to global plastic waste, and reducing plastic use in kitchens is a small but impactful step toward curbing this trend.

Reducing plastic usage also aligns with the Indian government’s Swachh Bharat initiative, which emphasizes cleanliness and waste reduction. By educating the public on the health risks associated with plastic, particularly when reheated, the government can encourage healthier, more sustainable choices in Indian homes.

As research continues to shed light on the harmful effects of plastic, it is becoming increasingly important for Indian consumers to adopt safer, more traditional materials for food storage and reheating.
