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.

Chronic inflammation can cause major diseases like type 2 diabetes, cardiovascular disease, and cancer; thus, while thinking about staying healthy for a long time, it is a very important part of it. The disease is also a silent one that silently harms tissues over time and serves as a major reason for lifestyle conditions like Type 2 diabetes, obesity, and heart disease. Thus, reversing it becomes very important,
Recent study by researchers at Ohio State University, published in the journal Molecular Nutrition and Food Research, is a ray of hope for reversing this issue through dietary changes. The study finds that the drinking of specially formulated tomato-soy juice may reduce inflammation.
This beverage has a couple of potent reasons behind its success in the study against inflammation, namely lycopene and soy isoflavones. Notably, lycopene has antioxidant and carotenoid properties that enable it to neutralize free radicals, which cause cellular damage and fuel chronic inflammation. On the other hand, soy isoflavones possess plant-based nutrients called flavonoids, which have unique anti-inflammatory properties that can copy or modulate hormone signaling to calm overactive immune responses.
Those taking soy foods around 60–80 grams daily can expect a 28–29 per cent reduction in blood pressure. One hundred grams of soy is roughly equivalent to one cup of cooked beans or lentils, or a palm-sized serving of tofu. Higher soy consumption led to a 19 per cent lower risk of hypertension. Soy foods additionally contain compounds called isoflavones, which may further contribute to blood pressure regulation.
The study shows that tomato-soy juice reduced three major pro-inflammatory proteins in the blood, including interleukin-12 (IL-12p70), interleukin-5 (IL-5), and granulocyte-macrophage colony-stimulating factor (GM-CSF). The drink also lowers tumor necrosis factor-alpha (TNF-α), which is linked with chronic inflammatory diseases.

Soy foods may support heart health. It is believed to reduce inflammation in blood vessels and improve their flexibility, lowering the risk of heart disease and stroke. Some studies even link soy consumption to a 15 percent lower risk of death from heart disease.
The ‘high-protein’ tag attached to soy products such as soya nuggets, soya chaap, and even soy milk is misleading. As industrially processed foods often contain 80 to 90 percent refined flour, consumers get empty calories that spike blood sugar, disrupt hormonal balance, and fuel inflammation.

Prime Minister Narendra Modi once again addressed the nation through his monthly radio broadcast, Maan Ki Baat. It was the 134th installment of the broadcast, and the Prime Minister urged the people of India to take extra precautions in summer's scorching heat.
The Prime Minister said, "It is very hot in most parts of the country right now. Strong sun, hot winds, it is very important to take care of yourself in such weather. Keep drinking water. If at all you have to go out in the sun, do so with caution." He added, "Don't forget the guidelines issued by various government departments in this regard."
Then the Prime Minister also addressed traditional food and drinking practices in different parts of the country to stay fit even during the hot summer. He urged the citizens to drink regional traditional drinks to stay hydrated and named popular options like Aam Panna, Sattu sherbet, Kokum sherbet, Sol Kadhi, Panakam, Neer Mor, Sambaram, Bael Pana, and Buttermilk. "Ek Bharat Shreshtha Bharat," he added.
The Prime Minister also mentions mangoes, which are a household summer treat in India. He said, "Every region… its own mango, its own flavor, its own aroma." Then he described these different mangoes and their specialties as well.
Prime Minister Narendra Modi also mentions the journey of the Indian mangoes from domestic production to the global market.
Drink water consistently at regular intervals instead of gulping large quantities at once. Electrolyte-rich fluids like coconut water, lemon water with a pinch of salt, or buttermilk are healthy, affordable options to soothe parched throats.
Add items like curd, rice, cucumber, and bottle gourd to your diet and avoid red meat and fried foods during peak summer days.
Extreme temperatures put additional stress on the cardiovascular system, especially in people with hypertension, diabetes, or heart conditions. Make sure to take all prescribed medications exactly as advised—don’t skip doses even if you experience heat-induced nausea. If you feel dizzy or experience palpitations or severe fatigue, consult your doctor as soon as possible.
Air conditioning is helpful, but overexposure can lead to dry skin, headaches, and respiratory discomfort. Once every two or three hours, step away from your desk for a few minutes. Walk or stand, and sip some water.

Sugary drinks are a very soothing option in summer, but come with several health-related issues like diabetes, fatty liver, and heart disease, to name a few. And now this list is getting a new addition, as a new study claims that sugary beverages can cause brain aging. This research is linked to the Framingham Heart Study.
As the Indian summer is in full sway, the demand for cold sugary drinks is also rising along with it. During the hot summer, people use these beverages as cooling drinks, and consumption also goes through the roof.
The researchers from the Boston University School of Medicine studied participants in the Framingham Heart Study Offspring and the Third Generation Study. The research was done on the possible impacts that sugar-sweetened beverages (SSBs) and artificially sweetened beverages (ASBs) have on the brain.
The study finds that consuming a large amount of sugary drinks was associated with a smaller total size of the brain and reduced volume of the hippocampus, which is a critical region in the brain essential for learning and memory.
The research points out that consuming too many sugary drinks can lead to inflammation, poor blood vessel function, and high blood sugar, which in turn might harm the brain.
Sugary drinks or sugar-sweetened beverages (SSBs) are drinks that are added with sugar, sweeteners, or syrups. Some of the common sugary beverages are carbonated soft drinks, energy or sports drinks, and fruit-flavored drinks.
Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.
You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor. Make this your new habit.
