Green tea, as told over and over again, is a healthier option. If, of course, consumed without sugar, as it is supposed to. But, is it really the safer option?

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.

Whole grains are becoming more popular day by day because of their nutritional benefits, and a recent study has highlighted another major advantage of eating four to six servings. According to the study published in the European Heart Journal, eating four to six servings of whole grains every day may help lower the risk of heart disease. As heart disease is arguably one of the most fatal ailments, these findings, if true, can give hope to millions.

The research shows that eating a diet rich in whole grains may help to prevent heart disease. The study emphasizes that these foods reduce body weight, blood pressure, cholesterol levels, and glucose in the blood, which in turn play a major role in lowering the risk of heart disease overall.

The lead researcher Dr. Helda Tutunchi from Tabriz University of Medical Sciences, Iran said, "Although higher whole-grain intake has long been linked to better heart health in population studies, clinical trials have produced mixed findings. This left an important practical question unanswered: How much whole grain should people eat to meaningfully improve cardiovascular health?"

"To address this, we systematically combined and analyzed all available randomized controlled trials to identify the amount of whole grain associated with the greatest benefits." She added.

The findings came after trials conducted across Asia, Europe, the United States, Canada, Australia, and Brazil. Notably, more than 6,500 people took part in these trials. The thorough analysis showed that whole grains significantly reduced people's body weight, waist circumference, and blood pressure, as well as levels of total cholesterol and low-density lipoprotein cholesterol, triglycerides, glucose, and interleukin-6, a sign of inflammation in the blood.

The study suggested that these benefits might be seen in those who eat 30 to 40 grams of whole grains per day, but the maximum benefits were found in people eating 60 to 100 grams per day. This amounts to around four to six servings of whole grains a day—for instance, oatmeal, a sandwich made with whole-grain bread, and a serving of brown rice.

In an accompanying editorial, Dr Cecilie Kyrø of the Danish Cancer Institute in Copenhagen and her colleagues noted that more than 50 years ago, Sir Denis Burkitt and his fellow researchers suggested that refining staple carbohydrates—and removing the cereal fibre in the process—could contribute to a wide range of Western diseases by affecting stool volume, bowel transit time and the environment within the colon.

Whole grains are cereal grains that retain all three major components—bran, germ and endosperm—in the same proportions found in the intact grain. They can be consumed as whole kernels or flakes, or ground into flour and used to make bread and other foods.

When we think of malnutrition, we often picture a child who is thin or underweight. But malnutrition can sometimes look very different. An overweight child can also be malnourished.

A child may consume enough—or even too many—calories and still not get the nutrients needed for healthy growth. Diets high in processed foods, sugary drinks and refined carbohydrates can lead to excess weight while being poor in iron, calcium, vitamin D, vitamin B12, protein and other essential nutrients.

This is particularly important today, when childhood overweight and obesity are increasing alongside micronutrient deficiencies. A child’s weight alone therefore cannot tell us whether the child is adequately nourished.

Parents need to look at the overall picture—growth pattern, height and BMI for age, dietary habits, physical activity and, when required, blood tests for specific deficiencies.

Parents should also remember that “eating more” does not always mean “eating better”. A balanced diet containing adequate protein, vegetables, fruits, whole grains and other nutrient-rich foods is essential.

The goal should not simply be a healthy weight, but a healthy, well-nourished child.

Multiple batches of synthetic paneer is making its way into Delhi-NCR kitchens, according to a recent investigation. It found that that some manufacturers were using slaked lime, commonly known as chuna, to whiten the non-dairy paneer.

An recent investigation by The Times of India found that synthetic paneer was being produced in Gondola village in Nuh's Punahana block and supplied to Delhi, Gurgaon and Faridabad.

Food safety officials reportedly found buckets of chuna during recent raids, which a food department source said was being used to artificially whiten the product.

The investigation also found that synthetic paneer can be made using ingredients like soya paste, milk solids, palm oil and other vegetable fats rather than milk. Haryana has since imposed a one-year prohibition on analogue or non-dairy paneer, while several other states have also taken similar action.

What Is Synthetic Paneer?

Analogue paneer resembles dairy paneer but is made partly or entirely from non-dairy ingredients.

It is not automatically illegal subject to certain conditions. They include properly labelled and meets applicable food regulations.

The concern arises when it is sold as ordinary dairy paneer or produced without adequate food-safety controls. But the nutritional differences between the two foods can be significant.

Risks Of Consuming Paneer Laced With Chuna

Chuna generally refers to calcium hydroxide, or slaked lime. The chemical has legitimate uses in certain food-processing applications when the appropriate food-grade material is used correctly. However, calcium hydroxide is alkaline and can be irritating or corrosive at sufficient concentrations.

According to the US National Institute for Occupational Safety and Health, exposure can cause irritation or burns involving the eyes, skin and respiratory tract, while ingestion can cause burning, abdominal pain, vomiting and other gastrointestinal injury.

HealthandMe spoke to Dr. Tushar Tayal, Associate Director, Internal Medicine, CK Birla Hospital, Gurgaon, about the risks of consuming synthetic paneer.

Dr. Tayal says, "Consumption of adulterated paneer may lead to gastrointestinal symptoms such as nausea, vomiting, abdominal discomfort and diarrhoea, particularly if the product contains unsuitable or contaminated ingredients. Excessive or inappropriate exposure to substances such as slaked lime can also irritate the mouth, throat and digestive tract. The health impact, however, depends on the substance used, its concentration and the amount consumed, so it would be inappropriate to assume that every adulterated paneer product will cause the same level of harm."

Dietician & Certified Diabetes Educator Ms Archana Batra told HealthandMe that fake paneer could interfere with one's daily protein intake. She also flags other health concerns.

She says, "From a health perspective, the only concern is not that fake paneer has low nutritional value. The real concern is that adulterated paneer contains substances that are not approved for food use, if we consume it then it can cause gastrointestinal discomfort such as nausea, vomiting, abdominal pain or diarrhoea. If we repeatedly get exposed to unknown chemical adulterants then it can place an unnecessary burden on the body. Adulterated paneer cannot replace the protein and other nutrients that are present in real paneer."

That does not mean that eating paneer whitened with chuna automatically causes chemical poisoning. The actual health risk would depend on the type and amount of calcium hydroxide used, its purity and how much remains in the food.

The bigger concern is therefore unknown composition and lack of food-safety control, particularly when consumers are led to believe they are buying nutritionally equivalent dairy paneer.

How To Identify Fake Paneer?

Experts suggest that natural paneer, made from the milk curdling process, has a firm texture with a milky smell. While regular paneer turns brown upon heat, synthetic paneer crumbles and melts quickly. FSSAI mandates that products using non-dairy substitutes must mention terms like "analogue" or "imitation" on the packaging.

Dr. Tayal further recommends, "Consumers should therefore be cautious about paneer that has an unusually bright white appearance, abnormal texture, chemical smell or an unusually low price. Buying dairy products from reliable sources and checking packaging, labelling and freshness can reduce the risk. If someone develops persistent vomiting, severe abdominal pain, breathing difficulty or other unusual symptoms after consuming suspected adulterated food, medical attention should be sought promptly."

As per FSSAI, an iodine test can also help with identifying fake paneer. Take a pan and boil paneer in it. Add a few drops of iodine tincture to the boiled paneer. If it turns blue, it's artificial.

Another trick to identify fake is the toor dal test. Allow the boiled paneer to cool in water. Add some toor dal to the water and let it sit for 10 minutes. If the water turns light red, then it is fake paneer.
