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.

Have you been diagnosed with oral cancer? Wondering if you can have your favourite fruit, mango? Then make sure to consult your doctor before having it. Though mangoes are rich in vitamins and antioxidants, oral cancer patients should consume them carefully, depending on their treatment stage and mouth condition. It is not a good idea for oral cancer patients to eat mangoes in large quantities.

Can oral cancer patients eat mangoes?

In an interaction with Health and Me, Dr. Amit Chakraborty, Head and neck onco-surgeon, Mumbai, shared some simple guidelines to help oral cancer patients satisfy their mango cravings healthily.

Everyone, including oral cancer patients, eagerly waits for the mango season. After all, it is difficult to resist mangoes, right? As summer and mangoes go hand in hand, even oral cancer patients may be tempted to eat them. Mangoes are packed with vitamins, antioxidants, and natural sweetness, but they should be eaten in moderation. However, oral cancer patients and those undergoing cancer treatment often wonder whether mangoes are safe for them. Understand that the answer depends on the patient’s condition, stage of treatment, and symptoms affecting the mouth and throat.

What happens when oral cancer patients eat mangoes often?

In many cases, ripe mangoes can be safely consumed by oral cancer patients because they are soft, nutritious, and easy to swallow. However, they should have only two to three small slices of mango per day. It is not advisable to eat an entire mango. Mangoes contain vitamins A, C, and E, along with antioxidants that help support immunity and overall health. They may also provide energy to patients who struggle with appetite loss during treatment. However, oral cancer patients can suffer from mouth ulcers, pain, burning sensations, dry mouth, difficulty chewing, or sensitivity due to chemotherapy, radiation, or surgery.

In such situations, very sweet, fibrous, or slightly sour mangoes may irritate the mouth and increase discomfort. Sticky mango pulp can also sometimes remain inside the mouth, making oral hygiene important. It is necessary to avoid sour and unripe mangoes. Mango pulp, smoothies, or mashed mango can be chosen by patients who have difficulty swallowing. Again, the expert will decide the quantity. If the expert does not allow it, then it is better not to eat mangoes. Maintaining proper oral hygiene after eating is equally important to prevent infections and irritation.

Conclusion

If you have oral cancer and want to eat a mango, choose a soft, ripe mango. Moderation is key, and maintaining oral hygiene is essential. As every patient’s condition is different, follow your doctor’s advice regarding cancer treatment. All you need to do is to ensure that you do not go overboard with the fruit, as it can do more harm than good if eaten mindlessly, especially with comorbidities.

In an interview with Health and Me, Dr Sandeep Talwar, Fertility Specialist, Nova IVF Fertility, East of Kailash, Delhi, said, "The thyroid gland plays a pivotal role when it comes to controlling metabolism, energy levels, hormones, and even reproductive health. When thyroid hormone levels become imbalanced, a large number of women experience signs and symptoms such as irregular periods, difficulty with ovulation, weight changes, fatigue, or fertility problems. You will be surprised to know that one of the key nutrients needed for proper thyroid function is iodine. Yes, you heard that right! However, many women don’t know much about it and fail to include it in their daily diet. So, by adding simple iodine-rich Indian foods to everyday meals, it is possible to improve thyroid and reproductive health. A balanced diet, along with regular medical check-ups, can make a positive difference, especially for women who are planning a pregnancy."

Iodine-Rich Indian Foods For Thyroid Health

These iodine-rich foods will be beneficial for Indians in maintaining thyroid health and supporting ovulation:

1. Curd and milk are commonly available iodine-rich foods in Indian households. They also provide calcium and protein, which support overall health during fertility planning. Try to have a bowl of curd or a glass of milk for healthy thyroid function.
2. Eggs contain iodine, protein, healthy fats, and vitamin D, which support hormonal and reproductive health. Have boiled eggs or egg-based dishes for breakfast. Also, the yolk contains iodine, so eating whole eggs in moderation is fine. Make sure to consult an expert before including them in your diet.
3. Fish such as tuna, sardines, and mackerel are rich in iodine and omega-3 fatty acids, which support thyroid health and hormone balance. People who consume non-vegetarian food can include fish once a week as part of a balanced diet.
4. Green leafy vegetables and dals support hormone health. Spinach, rajma, moong dal, and chana can be included in the diet. Though they may not contain very high iodine levels, they support overall reproductive and thyroid health.
5. Iodised salt helps maintain adequate iodine intake. Be cautious and consume it in moderation, as excess salt can increase blood pressure.

Including iodine-rich foods in daily meals, exercising regularly, and undergoing regular thyroid check-ups help improve reproductive health. On World Thyroid Day, it is advised to follow a balanced and healthy diet that will help you manage disorders while also meeting basic nutrition requirements.

Sugar is bad for health, and we have heard this several times, on loop. But little do people realise that not all forms of sugar are bad for your body - some sugars are naturally occurring and might actually be the sweet treat you need. Fructose, for instance, found in fruits, is not as bad as processed sugar. But it is still important to know when to stop. In an interview with Health and Me, Dr Nimitt Nagda, Consulting Physician, Zynova Shalby Hospital, Mumbai, explained how natural sugar is different from processed sugar.

What is natural sugar?

Natural sugars present in fruits and milk tend to have nutrients and fibre, while processed sugar often adds empty calories that can harm health when consumed excessively. This article helps to explain how natural sugars impact the body differently when compared to processed sugars. Read on to know more about this and make sure to avoid excess processed sugar. So, adhere to healthy eating habits.

Sugar is a part of many foods that are eaten by people on a daily basis. However, not all sugars affect the body in the same way. Natural sugars are present in foods such as fruits, vegetables, and milk, whereas processed or added sugars are found in sweets, soft drinks, packaged snacks, bakery products, and desserts. While both types provide energy, the body handles them differently. It is the need of the hour to understand the difference between the two, as excessive intake of processed sugar is linked to obesity, diabetes, heart disease, and fatty liver disease. So, be cautious when it comes to your well-being.

Is natural sugar better?

Natural sugars are usually accompanied by fibre, vitamins, minerals, antioxidants, and water content. Fruits contain fructose, but they also provide fibre that slows down sugar absorption into the bloodstream. This helps maintain stable energy levels and prevents sudden spikes in blood sugar. Milk contains lactose along with protein and calcium, making it more nutritionally balanced. When it comes to processed sugar, it is quickly absorbed by the body because it lacks fibre and nutrients. This can lead to rapid increases in blood sugar and insulin levels. Frequent consumption of sugary foods and beverages may increase cravings, weight gain, fatigue, diabetes, obesity, and fatty liver disease. Processed sugar also contributes to inflammation, tooth decay, and unhealthy fat accumulation in the body. Moreover, natural foods are more filling, whereas processed sugary foods often encourage overeating because they do not satisfy hunger for long.

Natural sugars consumed through whole foods like fruits and milk are generally healthier because they come with essential nutrients and fibre that support overall well-being. Processed sugars, when consumed in excess, can negatively affect health and increase the risk of several chronic diseases. Choosing natural food sources and limiting added sugars can help maintain better energy levels, weight control, and long-term health. So, make sure to pay attention to your health without fail and limit processed sugar.
