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.
Deep-fried foods make hormonal imbalance worse in women dealing with PCOD. (Photo credit: AI generated)
PCOD is a hormonal disorder common among women of reproductive age. It can cause irregular periods, excess androgen levels (leading to symptoms like acne and hirsutism), and polycystic ovaries. Diet plays a crucial role in managing PCOD symptoms, particularly by addressing insulin resistance, which is common in women with the condition, and reducing inflammation.
Dr S. K. Wangnoo, Senior Consultant, Endocrinology, Indraprastha Apollo Hospital, Delhi, in an interaction with Health and Me, listed the best and worst foods for women dealing with PCOD.

For your next cheat day, make an informed choice. (Photo credit: AI generated)
A fitness enthusiast follows a disciplined routine not just at the gym but in terms of diet as well. For any weight-loss or fitness-centric routine, diet is the most important component, as it makes all the difference. This means you would be eating clean and a limited amount of food to achieve a calorie deficit. Yet, many times, cravings take over. Do not fret—cheat days are not as bad as you may think. In fact, the occasional cheat day does more good than harm if one makes the right choices. In an interview with Health and Me, a nutritionist shared some of the most common cheat day food choices. The expert also ranked them on a scale from one to 10 depending on their nutritional value.
Prachi Mandholia, a Mumbai-based clinical nutritionist, said, “When it comes to ‘cheat day’ indulgences, I always tell my clients that enjoyment is important, but awareness is everything. Not all cheat foods are equally harmful; some can be relatively balanced if consumed mindfully.”
Mandholia listed 10 popular foods that most people love to eat on their cheat day. The expert also ranked the foods based on their nutritional value and their subsequent impact on health.
Steamed Momos: 6/10
A better pick among indulgent options, momos are steamed, which significantly reduces fat content. When filled with vegetables or lean chicken, they offer some nutritional value. However, the outer layer is made of refined flour (maida), which lowers fibre content and can spike blood sugar.
Papdi Chaat: 3/10
While delicious, this dish combines fried papdi, sweet chutneys, and curd, making it high in unhealthy fats and sugars. It lacks balance and can be heavy on digestion.
Gol Gappe (Pani Puri): 4/10
Despite the fried puris, the spiced water can aid digestion, especially when made with ingredients like mint and jeera. Adding sprouts improves protein content, but sweet chutneys reduce its overall score.
Chhole Kulche: 5/10
Chhole provides plant-based protein and fibre, but kulche made from refined flour make this dish less wholesome. Portion control is key here.
Pepperoni Pizza: 2/10
This is a highly inflammatory combination because of processed meats, excess cheese, and a refined flour base. It is high in saturated fats and sodium, with minimal nutritional benefits.
Garlic Bread: 2/10
Primarily refined carbohydrates topped with butter, garlic bread offers little beyond empty calories and should be consumed sparingly.
Alfredo Pasta: 2/10
Loaded with cream and refined pasta, this dish is high in fat and low in fibre, making it heavy and nutritionally poor.
Vada Pav: 3/10
A deep-fried potato patty inside a refined bun creates a carbohydrate-heavy, low-protein meal that can spike blood sugar quickly.
Pav Bhaji: 6/10
The bhaji contains a mix of vegetables, making it relatively nutrient-rich. However, excess butter and refined pav reduce its health quotient.
Chhole Bhature: 2/10
Deep-fried bhature paired with heavy chhole makes this a calorie-dense, gut-straining combination that can lead to insulin spikes.
Mandholia concluded that even when it comes to a cheat-day diet, moderation and smart swaps can make even cheat meals a little kinder to your health.
If you are craving watermelon this summer, here's what you must know about the fruit. (Photo credit: AI generated)
Watermelon is a popular summer fruit known for its high water content, making it excellent for hydration. It also contains vitamins A and C, and antioxidants like lycopene. While watermelon is a hydrating and nutritious fruit often recommended for summer, eating too much of it can have specific impacts on women with Polycystic Ovarian Disease (PCOD), particularly due to its sugar content and potential for digestive issues.
Dr S K Wangnoo, Senior Consultant, Endocrinology, Indraprastha Apollo Hospital, Delhi, while discussing the effects of watermelon consumption on women with PCOD, said that overconsumption of the fruit may lead to blood sugar spikes, which can worsen insulin resistance—a common characteristic of PCOD—and trigger symptoms such as weight gain and fatigue. The expert further explained why this happens.
Viveka Kaul, Chief Diabetes Educator & Nutritionist, Endocrinology Department, Apollo Hospitals, said, “Balanced nutrition plays a critical role in managing PCOD, particularly in regulating insulin response and reducing chronic inflammation, both of which are key drivers of the condition. What women eat throughout the day has a direct impact on blood sugar levels, which in turn influences hormonal balance and symptom severity.”
Foods that are high in fibre and protein help slow down glucose absorption, preventing sudden spikes in blood sugar that can trigger excess insulin release. Over time, repeated insulin spikes can worsen androgen production, leading to symptoms such as acne, irregular periods, and weight gain. Including healthy fats in the diet further improves insulin sensitivity and supports overall metabolic stability.
Viveka Kaul went on to say that frequent consumption of refined carbohydrates and sugary foods can keep insulin levels consistently elevated, making it harder to manage PCOD effectively. The focus should shift from restriction to balance and consistency. Pairing carbohydrates with protein or healthy fats, maintaining regular meal timings, and avoiding long gaps followed by heavy meals can help keep energy levels stable and prevent metabolic stress. Over time, these steady dietary habits can lead to meaningful improvements in both hormonal health and symptom control.
Ultimately, managing PCOD through diet is about building sustainable, everyday habits rather than following short-term fixes. Consistency in food choices, portion control, and meal timing can gradually improve insulin sensitivity and hormonal balance. When combined with regular physical activity and adequate sleep, these dietary practices can significantly reduce symptom severity and support long-term reproductive and metabolic health.
