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.

Nutritious food has become up to 25% more expensive over the past five years, leaving nearly one-third of the global population unable to afford a healthy diet, according to a new report released by the United Nations.
The 2026 State of Food Security and Nutrition in the World, published by the UN Food and Agriculture Organization (FAO), estimates that a healthy diet now costs an average of US$4.28 (S$5.52) in purchasing power parity (PPP) dollars per person per day.
"A healthy diet costs 25% more than it did five years ago. One-third of the global population can't afford it. The cost of a healthy diet shows where agrifood systems investments can have the greatest impact," Máximo Torero Cullen, the FAO's Chief Economist, wrote in a post on social media platform X.

The full report, to be presented on July 21 at the organization's headquarters in Rome, found that the cost of a healthy diet is unevenly distributed across different food groups.
"The challenge is not to produce enough calories; it is to make nutrient-rich foods more affordable," Torero said during a press conference, as quoted by AFP. The full report will be presented July 21 at the organization's headquarters in Rome.
He emphasized that strengthening local food production could significantly lower the cost of healthy diets.
Torero also highlighted two major uncertainties that could further drive up global food prices:

Amid intensified inspections and market surveillance by the Food Safety and Standards Authority of India (FSSAI) to crack down on counterfeit and substandard dairy products, a new survey has found that 6 in 10 urban Indian households are not fully confident about the purity and quality of the ghee or clarified butter they consume.
The survey, conducted by community social media platform LocalCircles, received over 91,000 responses from more than 18,000 urban consumers across 293 districts, revealing widespread concern over adulteration—particularly in loose and unbranded ghee.
According to the survey:
The findings come amid a series of enforcement actions by FSSAI targeting fake and substandard dairy products across India.

In December 2025, FSSAI directed all States and Union Territories to launch a nationwide enforcement drive against the adulteration and misbranding of milk and milk products, including ghee, paneer and khoya, under the Food Safety and Standards Act, 2006.
Since then, the regulator has significantly expanded inspections and surveillance. Recent enforcement actions include:
FSSAI has also issued notices to quick-commerce platforms over complaints of expired and spoiled food products being delivered to consumers.
Made by clarifying butter obtained from cow's milk, ghee is a staple in Indian kitchens and contains approximately 130 calories and 15 grams of fat per tablespoon. It is also a rich source of vitamins A, D, E and K, along with antioxidants.
However, because ghee is high in saturated fat, excessive consumption may raise LDL ("bad") cholesterol levels in some individuals and increase the risk of cardiovascular disease.

Health experts advise people with certain medical conditions to consume ghee cautiously or avoid it altogether.
These include people with:
Doctors generally recommend limiting intake to no more than two teaspoons a day, unless advised otherwise by a healthcare professional.
Food adulteration involves the deliberate addition of inferior or harmful substances to food products, compromising their quality and safety.
According to a 2024 study published in SAGE Open Medicine, consuming adulterated food may increase the risk of:
The study notes that children, pregnant women and older adults are particularly vulnerable to the harmful effects of adulterated food.

India has approved its first plant-based Vitamin D3 (cholecalciferol) ingredient, a move that could expand options for food fortification and dietary supplements while addressing the country's widespread Vitamin D deficiency.
The Food Safety and Standards Authority of India (FSSAI) has cleared VITADEE Green, developed by Fermenta Biotech,for use in health supplements, nutraceuticals and food products.
The company stated that the ingredient is produced using an India-patented process and offers a sustainable, scalable and vegetarian-friendly source of Vitamin D3.
The approval allows Indian manufacturers to incorporate the ingredient into fortified foods, beverages and dietary supplements.
It is particularly significant for vegetarians and vegans, who have traditionally had limited access to Vitamin D3 because most supplements are derived from lanolin, a by-product of sheep's wool.
The approval also supports India's broader efforts to improve nutrition through food fortification, an area where experts say Vitamin D remains a major gap.
Studies suggest a large proportion of Indians have inadequate Vitamin D levels despite abundant sunlight, largely due to urban lifestyles, limited outdoor exposure and reduced sun exposure.
"Vitamin D deficiency remains a widespread public health concern in India, and the demand for sustainable nutrition continues to grow rapidly. The FSSAI approval allows us to bring VITADEE Green directly to Indian food fortification and nutraceutical manufacturers, helping bridge the nutrition gap for the country's large population," said Prashant Nagre, Managing Director, Fermenta Biotech.
For India's large vegetarian population, the approval also brings a domestically manufactured, regulatory-approved plant-source Vitamin D3 to the market.
Vitamin D3, often called the "sunshine vitamin," is produced by the body when the skin is exposed to sunlight.
It helps the body absorb calcium, maintain healthy bones and teeth, and lowers the risk of fractures. In children, severe deficiency can lead to rickets, while in adults it increases the risk of osteoporosis, muscle weakness and falls.
Beyond bone health, Vitamin D3 also supports immune function. Research suggests low Vitamin D levels may be associated with increased susceptibility to infections and higher levels of inflammation.
Despite abundant sunshine, Vitamin D deficiency is common across India. Experts attribute this to long hours spent indoors, limited outdoor activity, sunscreen use, ageing and diets naturally low in Vitamin D.
Low Vitamin D levels can lead to weak bones, muscle weakness and an increased risk of fractures. In children, severe deficiency can cause rickets, while inadequate levels have also been linked to poorer immune function.
"Vitamin D deficiency remains a widespread public health concern in India, and the demand for sustainable nutrition continues to grow rapidly," said Prashant Nagre, Managing Director of Fermenta Biotech.
Doctors say no—not in terms of effectiveness.
Dr. Murtaza S. Bagwala, Head of Emergency Medical Services at Saifee Hospital, Mumbai, told HealthandMe that current evidence shows plant-based Vitamin D3 raises Vitamin D levels just as effectively as conventional supplements.
"Based on current science, plant-based Vitamin D3 is comparable to conventional Vitamin D3 supplements. For most people, it is a good alternative if they prefer a plant-based product," he said.
Dr. Sudhir Kumar, Neurologist at Apollo Hospitals, Hyderabad, explained that plant-derived Vitamin D3—typically sourced from lichen, algae or newer fermentation technologies—offers an animal-free option without compromising efficacy.
"It is good news for consumers who prefer vegan products, but both forms are equally effective. There is no medical reason for people to switch if they are already taking conventional Vitamin D3," he said in a post on X.
The experts said the key question is whether supplementation is needed, not whether the source is plant- or animal-derived.
"The source matters mainly for ethical, dietary or personal preference—not for efficacy," Dr. Sudhir said.
Dr. Bagwala cautioned against taking high-dose Vitamin D without medical advice, as excessive intake can raise calcium levels and increase the risk of kidney stones and other complications.
Doctors recommend that supplementation should be based on:
