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.

What were the findings?

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.

How was the study conducted?

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.

How was the test conducted?

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.

Health Impacts

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.

One extra serving of leafy greens like kale and spinach may be good for your lungs and help you breathe better, according to a study. The secret? It is the vitamin K1 found in leafy green vegetables.

Researchers from Edith Cowan University (ECU) tracked more than 179,000 adults over a decade and found that people who eat more vitamin K1-rich foods such as leafy green vegetables may lower their risk of chronic lung disease and boost lung function.

“We found that people who ate more vitamin K1-rich green vegetables had better lung function and were less likely to develop COPD,” ECU researcher Chengfeng Li said.

“Just one extra serve of leafy greens like kale, about one and a half to two cups a day, is an achievable way to boost your vitamin K1 intake,” Li added.

What Are The Key Findings

The findings suggest that adding more greens to your plate could help keep your lungs in better shape as you age.

The study found that those with the highest intake of vitamin K1 had about a 16 per cent lower risk of COPD compared to those eating the least.

They also had better lung performance, meaning their lungs could hold and move more air, a key sign of good respiratory health.

“Vitamin K likely activates a protein that protects the lungs’ elastic fibers - the tiny structures that let your lungs expand and contract,” Associate Professor Marc Sim said.

“When these fibers break down, breathing becomes harder over time. This nutrient may help keep lung tissue flexible and prevent damage,” Sim added.

The second type, vitamin K2, showed no benefit for COPD risk, though it was linked to somewhat better lung function at moderate intakes.

The researchers think the same protective mechanism probably applies to vitamin K2, but any benefit may be masked by what it's eaten alongside.

K1-rich leafy greens, by contrast, come with their own bonus nutrients like fiber and antioxidants that may boost the effect, while K2's main sources, including processed and red meat, are linked to poorer health outcomes.

The study also found no link between vitamin K and asthma, suggesting vitamin K may be more relevant for long-term lung damage rather than allergic conditions.

Smoking May Dent Benefits

While the boost from greens appears favorable, researchers are clear on one thing: it won’t cancel out smoking.

“The biggest thing you can do for your lungs is to quit smoking and reduce your exposure to environmental pollution,” Li said.

“But a healthy diet may still play a supporting role by counteracting some of the damage caused by these harmful factors.”

“Eating more leafy greens is a simple step that could help support lung health over time.”

How To Keep Your Lungs Healthy?

The World Health Organization data shows that chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death worldwide. The condition was responsible for an estimated 3.5 million deaths in 2021, according to the latest available global data.

COPD is a common and serious lung disease, and the WHO noted that smoking, indoor and outdoor pollution, and harmful inhalants are among its most significant triggers.

If your breathing feels effortless, steady, and natural, so much so that you barely notice it, your lungs are likely in good shape. To maintain this good lung health, it is essential to:

• maintain a balanced weight,
• eating nutritious food,
• exercise regularly,
• avoiding tobacco,
• avoiding vaping,
• keep away from inhaled irritants.

For years, weight loss advice has been dominated by a single message: eat less. From crash diets to extreme calorie counting, the assumption has been that consuming fewer calories is the ultimate solution to obesity. While reducing excessive calorie intake can contribute to weight loss, the reality is far more complex. Sustainable weight management requires understanding the science of metabolism, behaviour, hormones, sleep, stress, and long-term lifestyle patterns rather than relying solely on restriction.

Why Restrictive Diets Don't Help

The human body is not a simple mathematical equation. It is an adaptive system designed to protect itself. When calorie intake is drastically reduced, the body often interprets this as a potential threat and responds by slowing metabolism to conserve energy. Hunger hormones such as ghrelin increase, while hormones responsible for satiety decrease. As a result, people often feel hungrier, more fatigued, and less motivated over time.

This explains why many restrictive diets may show short-term success but fail to deliver sustainable outcomes. Initial weight loss is often followed by plateaus or weight regain, leaving individuals frustrated and blaming themselves for lacking discipline. In reality, biology plays a significant role in resisting prolonged calorie deprivation.

Food Quality and Lifestyle Factors

Equally important is the quality of food being consumed. Two meals with the same calorie count can affect the body very differently. Diets rich in processed foods, refined sugars, and unhealthy fats can lead to rapid blood sugar fluctuations, increased cravings, and poor satiety. On the other hand, balanced meals containing adequate protein, fibre, healthy fats, and micronutrients help regulate appetite and support metabolic health.

Lifestyle factors also play a critical role in sustainable weight management. Chronic stress elevates cortisol levels, which may contribute to increased fat storage and emotional eating. Poor sleep disrupts hormones that regulate hunger and fullness, often increasing cravings for high-calorie foods while reducing energy levels for physical activity. Sedentary lifestyles further compound the issue.

Weight loss is also deeply connected to behavioral and emotional health. Many eating habits are influenced by stress, social environments, routines, and emotional triggers rather than true hunger. Advising someone to “just eat less” overlooks these underlying drivers. Without addressing behavioral patterns, sustainable change becomes difficult.

This evolving understanding of obesity has shifted the conversation from blame and willpower to science and personalized care. Today, obesity is increasingly recognized as a chronic, multifactorial condition that requires comprehensive management strategies tailored to individual needs.

Lifestyle modifications such as balanced nutrition, regular physical activity, sleep optimization, and behavioral counselling remain the cornerstone of treatment. However, for some individuals, especially those struggling with obesity-related health concerns or repeated cycles of weight regain, lifestyle interventions alone may not always be sufficient.

Endoscopic Procedures

In recent years, minimally invasive endoscopic procedures have emerged as additional tools within medically supervised weight management programs. Procedures such as endoscopic sleeve gastroplasty (ESG) help reduce stomach volume to promote early satiety, while intragastric balloons can aid portion control and behavioral modification. Transoral outlet reduction (TORe) may also help individuals experiencing weight regain after bariatric surgery.

These procedures are not shortcuts or substitutes for healthy habits. Instead, they work in conjunction with long-term dietary and lifestyle interventions to support sustainable outcomes in appropriately selected patients.

Sustainable Weight Loss

Ultimately, sustainable weight loss is not about punishing the body through extreme restriction. It is about understanding how the body functions, identifying the biological and behavioral factors influencing weight, and creating realistic, long-term strategies that support overall health.

The future of weight management lies not in simplistic advice, but in compassionate, science-backed, and personalized care. Only by moving beyond the outdated “eat less” narrative can we create healthier and more sustainable approaches to obesity management.

India's food regulator, FSSAI, has issued notices to six beverage brands, including Red Bull and PepsiCo India, for claiming to be "energy drinks," citing misbranding and misleading claims.

The brands include:

• Red Bull Energy Drink
• PepsiCo – Adrenaline Rush Energy Drink
• Reliance Consumer Products – Campa Energy Gold Boost
• Sting Energy Drink
• Hell Energy
• Coca-Cola-backed Monster

Why FSSAI Issued Notices

The FSSAI, in a post on social media platform X, noted that it has not notified any standard for "energy drink" or similar products.

The regulator stated that these brands have "marketed using descriptors such as 'energy drink' on product branding and labelling."

The FSSAI further said that the Food Category System under the FSS Regulations is not intended for product naming or labelling purposes.

"Functional or therapeutic claims, including but not limited to 'vitalizes body and mind', 'enhancing focus', 'boost energy levels', 'aid in general weakness', or similar conditions, are not permissible for food products under the FSS Act 2006 and the Rules and Regulations made thereunder," the regulator said.

Recently, Maharashtra State FDA Minister Narhari Zirwal told the Assembly that the state is set to ban the sale of Sting energy drink within 500 meters of schools.

Are Energy Drinks Healthy?

Energy drinks have become a fad among the youth population and are linked to rising fitness awareness. According to the IMARC Group, India's energy drinks market was valued at $1.5 billion in 2025 and is projected to reach $2.9 billion by 2034.

However, Dr. Sudhir Kumar, neurologist at Apollo Hospitals, Hyderabad, said energy drinks may not actually provide "energy."

Rather, they are loaded with "caffeine, sugar and stimulants" that may not be healthy and are "not necessary for exercise, gym workouts or sports."

"Some studies suggest caffeine can improve alertness and endurance in certain athletes. But that doesn't mean everyone who goes to the gym or for a morning run needs an energy drink. Most recreational exercisers do not need energy drinks," said the noted neurologist known popularly as Hyderabad doctor.

He noted that for people working out for less than an hour: "Water is usually enough".

"If you need extra fuel, ordinary carbohydrate-rich foods, such as a banana, fruit, dates or a simple meal, are often safer and cheaper than an energy drink".

Dr Sudhir also noted the downsides of energy drinks many of which contain large amounts of added sugar, high doses of caffeine and multiple stimulants whose combined effects are not always well studied.

He liked excess intake of energy drinks with:

• Weight gain
• Obesity
• Type 2 diabetes (especially sugar-sweetened drinks)
• High blood pressure
• Sleep disturbance
• Anxiety and palpitations
• Dangerous heart rhythm problems."

Over the past few years, there has been a significant increase in young patients presenting with liver dysfunction. Energy drinks may be one of the culprit, according to Dr. Abhideep Chaudhary, President of the Liver Transplantation Society of India (LTSI) and Chairman and Head, Department of HPB and Liver Transplantation, BLK-Max Hospital, New Delhi.

"Three major contributors stand out — energy drinks, alcohol, and high-sugar beverages. Energy drinks, often perceived as harmless, contain high levels of caffeine, sugar, and chemical additives that place immense stress on the liver," the doctor said.

Who Should Avoid Energy Drinks?

Dr. Sudhir suggested people should avoid or strictly limit energy drinks if they are:

• Children and adolescents
• Pregnant or breastfeeding women
• People with heart disease
• People with hypertension
• People with anxiety disorders
• People with sleep problems.
