While, technically, it is, but the packaging might make it harmful for us. As per a November 2024 study published in Chemosphere, researchers tested three different brands of tea bags for exposure of microplastics, which are also degraded plastic bits that do not breakdown and found that it could impact human health.
The team found that brewing tea in polypropylene, essentially plastic bags, or a common tea bag material actually released over a billion particle per milliliter of tea. In fact, what we think as the paper bags, made of cellulose and mesh nylon bags also shed millions of plastic particle per milliliter.
John Meeker, a professor of Environmental Health Sciences and Global Public Health at the University of Michigan School of Public Health said finding such high amounts of micro and nanoplastics in a product that is supposed to be consumed is a cause of concern.
The researchers first extracted plastics from brewed tea and then exposed them to human intestinal cells that absorbed the plastic particles. It showed that microplastics could remain in the body even after drinking the tea.
The study author Alba Garcia-Rodriguez, a researcher in the Department of Genetics and Microbiology at the Universitat Autonoma de Barcelona said the research calls attention to the path of substantial exposure to plastic particles which are also found in everyday lives. "We have to be concerned about the huge number of single-use plastic that humans are exposed to daily," she said.
Similar tests have been conducted previously. In 2019, a Canadian study was the first one to test nylon and polyethylene tea bags which released 11.6 billion microplastics and 3.1 nanoplastics, measuring less than a micron into a single cup of tea.
In another study from 2023, conducted by Garcia-Redriguez and colleagues, one brand of tea bags were tested that was made of polylactic acid, a biodegradable plant-based plastic. The study showed that it released 1 million nanoplastic particles per tea bag.
For this 2024 study, the research team set broadened their scope by testing out for various materials. They obtained empty tea bags made from three commonly used materials: polypropylene, nylon, and cellulose.
The team simulated typical tea-brewing conditions (without tea leaves) by steeping the bags in sterile water heated to 95°C (203°F) while stirring continuously. They then measured how many plastic particles each material released.
The results revealed that polypropylene bags shed the highest amount of microplastics—approximately 1.2 billion particles. Cellulose paper bags came next, releasing 135 million particles per milliliter, while nylon mesh bags released 8.18 million particles.
The study revealed that hot temperature water exposure and also the stirring of spoon can cause tea bags to "leach plastics".
When the plastics were exposed to humans, it showed that cells absorbed the microplastics, including the mucus cells, as they had the highest uptake of particles. After 24 hours, the particles reached the nucleus of the cells, which houses the DNA.
Experts find the results concerning, as ingested microplastics could enter the bloodstream after targeting tissues in the gastrointestinal tract, potentially spreading to other organs. While chemicals added during plastic production have been linked to issues like endocrine disruption and cancer, the health effects of ingested microplastics remain unclear. Scientists caution against drawing conclusions, noting that human studies on microplastics are still limited and much more research is needed.
How can one reduce the exposure to plastics? The best way possible is by buying loose leaf, even when you are using green tea, which, is mostly used in tea bags, as a way to make it instantly. In case you are in rush, you can always use the steel infuser to use it as a replacement of plastic tea bags for an instant cup of tea.

The monsoon season offers relief from the heat but also creates the perfect environment for bacteria, viruses, and fungi to multiply. As a result, stomach infections, food poisoning, diarrhea, and indigestion become more common.
Thus, fermented foods act as a natural probiotic to keep the gut healthy during the rainy season. They also support digestion, improve nutrient absorption, and may reduce the risk of digestive problems during the rainy season. However, the humidity can spoil the food.
HealthandMe spoke to experts who stressed good hygiene and freshly cooked meals. They also called for foods to be prepared
and stored safely to prevent contamination.
Common probiotic-rich homemade foods include:
The experts said that homemade fermented foods naturally contain beneficial bacteria (probiotics) that help maintain a healthy gut microbiome.
"Monsoon brings a natural dip in immunity, and gut health takes centre stage in staying resilient through the season. Fermented foods are one of the simplest ways to introduce live beneficial bacteria that aid digestion and strengthen the body's natural defence mechanisms," Dr. Eileen Canday, Head of Nutrition & Dietetics at Sir H. N. Reliance Foundation Hospital, Mumbai, told HealthandMe.
Riya Oswal, Clinical Nutritionist at Ruby Hall Clinic, said pairing good hygiene with probiotic-rich fermented foods can help support gut health and strengthen the body's natural defenses.
Despite their benefits, fermented foods can become unsafe if they are not prepared or stored properly.
"The higher humidity and fluctuating temperatures during the monsoon create favorable conditions for harmful microorganisms if fermentation is not properly controlled," Dt. Deepali Sharma, Clinical Nutritionist at CK Birla Hospital, Delhi, told HealthandMe.
Food safety becomes especially important during the rainy season. The experts recommended to:
Do not consume homemade fermented foods if they show signs of spoilage. Discard them if you notice:
"Any fermented item that has been maintained at a temperature beyond the normal room temperature for too long must also be avoided, since it might carry dangerous microbes, even if everything seems fine at first glance," she said.
While fermented foods are generally safe for healthy individuals, some people should consult a doctor before consuming homemade fermented products, Oswal told HealthandMe.
These include:
Sharma added that infants, older adults with reduced immunity, and pregnant women should consume only freshly prepared and properly stored fermented foods during the monsoon to minimize the risk of infection.

The Indian Council of Medical Research–National Institute of Nutrition (ICMR-NIN) has launched a new policy document aimed at tackling childhood obesity and promoting healthier diets and food environments for children and adolescents in India.
Released under the multi-institutional 'Let's Fix Our Food' (LFOF) consortium, which was launched in 2022, the policy comes as India faces a growing burden of obesity and diet-related non-communicable diseases (NCDs), including diabetes, hypertension, cancer and respiratory illnesses.
The document outlines evidence-based recommendations to improve food environments and encourage healthier dietary habits among children and adolescents.
"Evidence-based, multisectoral policy action is essential to create healthier food environments for children and adolescents. Collaborative initiatives such as the Let's Fix Our Food Consortium are important for addressing the growing burden of overweight, obesity and diet-related non-communicable diseases in India," said Dr. M. Srinivas, Member (Health), NITI Aayog.
The policy outlines recommendations across several areas, including:
The policy highlights India's growing double burden of malnutrition.
According to the National Family Health Survey-6 (NFHS-6) fact sheets for 2023–24, the prevalence of overweight children under five has increased to 3.4%, up from 2.1% in NFHS-4 and 1.3% in the previous survey.
The survey also found that although stunting among children under five has declined to 29.3%, acute malnutrition (wasting) remains unchanged at 5.2%, and only 15% of young children receive an adequate diet.
"Malnutrition is no longer only about undernutrition. Rising obesity, driven by unhealthy diets, challenges healthy growth among children and adolescents," said Marie-Claude Desilets, Chief of Nutrition, UNICEF India.

The Let's Fix Our Food Consortium was established to generate evidence and drive policy action for healthier food environments, particularly for children and adolescents. Based on multidisciplinary research and expert consultations, the policy recommends:
The consortium also launched practical tools to help schools and adolescents make healthier food choices.
The initiative is supported by several national and international organizations, including UNICEF India, the Global Health Advocacy Incubator (GHAI), the Public Health Foundation of India (PHFI), the World Health Organization (WHO), the Food Safety and Standards Authority of India (FSSAI), and other partners.

Global hunger declined for the third consecutive year in 2025, but an estimated 645 million people still went hungry, while rising food prices linked to the Middle East conflict threaten to slow progress, according to a new UN report.
An estimated 7.8 percent of the global population—around 645 million people—were affected by hunger in 2025, down from 8.1 percent in 2024 and 8.6 percent in 2022, according to The State of Food Security and Nutrition in the World 2026 (SOFI 2026) report released on Tuesday by five UN agencies—FAO, IFAD, UNICEF, WFP and WHO.
The figure represents 14 million fewer hungry people than in 2024 and 43 million fewer than in 2022, marking the third consecutive year of improvement.
"While we welcome the clear progress we have made in reducing hunger, a healthy diet still remains unaffordable for one in three people globally. Obesity is rising and progress on maternal and child nutrition is stalling," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

Despite the decline in hunger, 25.8 percent of the world's population—around 2.1 billion people—experienced moderate or severe food insecurity in 2025, meaning they were forced at times to compromise on the quality or quantity of the food they consumed.
This is down from 27.1 percent in 2024 and 28.7 percent in 2020, equivalent to 86 million fewer people than in 2024 and 135 million fewer than in 2020, although levels remain above those seen before the COVID-19 pandemic.
Africa is now home to the largest number of hungry people, with 309 million affected.
More than half (56.6 percent) of Africa's population experienced moderate or severe food insecurity in 2025, compared with:
Women continue to be disproportionately affected by food insecurity, although the gender gap narrowed slightly in 2025.
The report warned that the ongoing Middle East conflict could delay global efforts to end hunger by driving up food prices through higher energy and fertilizer costs.
Depending on how long the crisis affects food inflation, 510–520 million people could still face hunger by 2030, compared with 503 million projected before the conflict, the report said.
It also noted that other risks—including extreme weather events such as El Niño in 2026 and 2027—were not included in these projections and could further worsen the outlook.
The report warned that the conflict, combined with extreme weather and declining humanitarian funding, threatens to reverse recent gains in reducing global hunger.
"This report is a stark reminder that food systems fail millions of children and families. Food, health, education and social protection must go hand in hand to protect the most vulnerable children and women from global shocks," said UNICEF Executive Director Catherine Russell.
Nutritious food has become up to 25 percent more expensive over the past five years, leaving 2.69 billion people—nearly one in three globally—unable to afford a healthy diet.
The average global cost of a healthy diet rose to US$4.28 (PPP) per person per day in 2025, up from US$3.44 in 2021 and US$2.94 in 2017.
Dr Ghebreyesus urged governments to adopt policies that make "healthy food the easy choice," including promoting breastfeeding, front-of-pack nutrition labelling, taxing unhealthy products, and protecting children from harmful food marketing.
"Healthy diets are not a luxury—they are the foundation of health and must be within everyone's reach," he said.
