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.

The West Bengal government’s recent move to substitute eggs with soybean, paneer, and other vegetarian sources in Kolkata’s midday meal scheme has been met with mixed responses. Amid concern for protein deficiency in children, we took a deeper look into the eggs vs soybean debate.

Eggs Vs Soya: Which Is Better?

After the International Society for Krishna Consciousness (ISKCON) took over midday meal duties in Kolkata, it switched to an all-vegetarian diet that entailed removing eggs. The move sparked a debate about the efficacy of vegetarian sources of protein, especially plant-based ones like soybean.

Experts believe that it's not a matter of one food vs the other but understanding the distinct nutritional benefits of each.

HealthandMe spoke to Dr. Aaryin Memon, Clinical Nutritionist, Bhailal General Amin Hospital, Vadodara, about the impact of relying on soybean for protein instead of eggs.

Dr Memon says that protein is one of the key nutrients during childhood and plays a role in the growth, development of muscles, immunity, and brain function. She says that eggs and soybeans are both good sources of protein, but they have different nutritional profiles and impact on the body.

As we have always been told that eggs are the gold standard when it comes to protein for the following reasons:

• Eggs contain all nine essential amino acids in highly available forms.

• Eggs are packed with vitamin B12 and vitamin D.

• Eggs also contain choline, selenium, and healthy fats.

Additionally, eggs are important for growing children as they contribute significantly in all-round development.

The expert says, “They contain a great amount of choline, which is essential for brain development, memory, and learning.”

When it comes to vegetarian sources of protein that match the nutritional value of eggs, soybeans are one of the top on the list. It is an excellent source of protein, dietary fibre, iron, calcium, magnesium, and beneficial plant compounds including isoflavones.

Soya can also help satisfy children's nutritional requirements and is a recommended vegetarian source of protein, according to nutritionists. It is also inexpensive, readily available, and appropriate for egg-free children's diets due to dietary, religious, or cultural preferences.

But the nutritionist points out that there are differences in their nutritional profiles.

Dr Memon says, “Soybean is a good source of protein, but plant protein is less bioavailable than animal protein. Certain nutrients like vitamin B12 are not found in plant-based protein sources. Additionally, the iron found in soya does not get absorbed in the body as well as iron from animals.”

Soybeans’ comparatively weaker nutritional profile is the reason why vegetarians have to rely on a diverse range of high protein foods like pulses, dairy products, legumes, nuts and seeds, as well as foods rich in vitamin C to support iron absorption, like fruit and vegetables.

This brings us to the conclusion that school meal programmes should embrace an 'either-or' option and include eggs and well-planned vegetarian options where possible. This enables children to have the right kind of nutrition and takes into account differences in their diets.

Heartburn and bloating are common indicators of indigestion. According to the US National Institute of Health, more than one billion people worldwide suffer from heartburn and related acid reflux, while nearly 18 per cent of the global population suffers from chronic bloating weekly.

Spicy foods are commonly blamed for heartburn and bloating; however, Dr Saurabh Sethi, a Harvard-trained gastroenterologist, has debunked this myth by claiming five recurring habits that he has seen common amongst such patients in his vast years of experience.

Addressing these underlying issues may help improve symptoms before turning to additional medications, he said, in an Instagram Post.

• Not enough fiber in the diet

Topping the list is a problem that affects a large portion of adults: inadequate fiber intake.

Fiber plays a critical role in maintaining a healthy gut microbiome and supporting regular digestion.

”A fiber-depleted gut feeds the wrong microbes, leading to excess gas and bloating,” Dr. Sethi said. The daily fiber intake target for an adult should be between 25 and 38 grams, which most adults fail to meet.

• Chronic stress

The connection between mental health and digestive health is stronger than many people realize.

The gastroenterologist stated that the gut-brain axis, the communication network linking the digestive system and the brain, is real, and stress can alter gut motility, increase symptom perception, and worsen both bloating and reflux.

• Wrong use of Peppermint

Peppermint tea is a naturally caffeine-free herbal infusion made from leaves of the peppermint plant, widely enjoyed to soothe digestion and reduce bloating.

However, it can cause the opposite of treating bloating by relaxing the lower esophageal sphincter and worsen heartburn.

“You may be treating one symptom while triggering another,” said the specialist, who has performed over 1000 endoscopies.

• Lying down after the meals

Another common habit among patients with chronic heartburn is lying down shortly after meals.

The doctor explained that gravity is the best antacid, and lying down within 2 to 3 hours of eating can cause heavy acid reflux. Dr. Sethi claims that he sees this pattern in chronic heartburn patients every week.

• Eating too fast

Many people rush through meals without realizing the impact it can have on digestion. One of the biggest contributors to bloating is swallowed air, which increases significantly when people eat too quickly.

"Your stomach isn't a trash compactor," said the gastroenterologist. He also talked about how fast eaters swallow significantly more air than slow eaters.

Dr Sethi said that for people struggling with chronic heartburn and bloating, the solution may not always involve eliminating spicy foods or adding another medication.

From the United States to India, the problem of food-borne diseases is constantly on the rise. The Morbidity and Mortality Weekly Report found that 402 US foodborne disease outbreaks were caused by marine toxins in fish and shellfish over the last 23 years, and the researchers also revealed that foodborne diseases caused 1,280 illnesses, 96 hospitalizations, and one death.

The research team from the Centers for Disease Control and Prevention (CDC) and the Oak Ridge Institute for Science and Education parsed data from the CDC’s Foodborne Disease Outbreak Surveillance System (FDOSS) from 2011 to 2023. The data have been provided voluntarily by the local state and health authorities to FDOSS through the CDC’s National Outbreak Reporting System since 2009.

Improper storage of fish at uncontrolled temperatures can lead to the formation of histamine, a compound that may trigger allergic reactions in people. It can also promote the production of scombroid toxins by bacteria that contain the highly active enzyme histidine carboxylase. In addition, other marine toxins may originate from algae and accumulate in fish and shellfish through the food chain, occur naturally in certain fish species, or arise from as-yet unidentified sources.

The authors of the study said that marine toxins cause most of the noninfectious outbreaks reported to FDOSS each year. They also wrote, “Marine toxins that cause foodborne illness are tasteless, odorless, resistant to cooking or freezing, and can produce a complex variety of gastrointestinal, neurologic, and neuropsychologic symptoms.” Then added, “Among persons with severe illness resulting from ingestion of marine toxins, cardiovascular and respiratory manifestations can result in hospitalization and death.”

FSSAI Introduces Stricter Quality Checks For Seafood

The contamination through seafood has also compelled the Food Safety and Standards Authority of India (FSSAI) to bring forth a stricter quality check for them. Recently, India’s food regulator has introduced new safety standards across a wide range of foods, and one of them was seafood, such as prawns.

The draft regulations by the Food Safety and Standards Authority of India (FSSAI) cover heavy metals, toxins, antibiotic residues, and quality standards for both commonly used foods and emerging edible products, the Times of India reported. The new regulations are expected to come into force on December 1.

Notably, the FSSAI's new safety standards will also apply to a wide range of foods, such as besan or gram flour, edible and cold-pressed seed oils.

In a separate draft notification, the FSSAI proposed quality and safety standards for lesser-used edible oils made from chilli, tomato, muskmelon, and okra seeds as demand rises for cold-pressed oils, seed-based snacks, and plant-based nutrition products.

The draft rules also cover edible seeds such as watermelon, cucumber, pumpkin, sunflower, sesame, and flaxseed sold in raw, roasted, or salted forms, requiring them to be clean and free from insects, fungus, and visible contamination before sale.
