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.

Kennedy Jr. recently revealed how he lost 20 pounds in 20 days on a highly restrictive diet focused completely on meats and fermented foods.

In an interview with USA Today’s “The Excerpt” podcast, the US Health and Human Services Secretary revealed that he followed the diet the whole day. “That may not be right for other people, but I lost 40 percent of my visceral fat within a month”. His eating habits have been highlighted before; previous interviews revealed he ate a steak along with fermented vegetables for breakfast.

However, is carnivorous die ideal for weight loss and are there any major concerns related to solely living on different kinds of meats?

Is A Carnivorous Diet Health?

A "carnivore" diet contains only animal products such as meat, eggs, and dairy. Kennedy Jr. also mentioned fermented foods, which include sauerkraut, yogurt, or miso, that are made using natural bacteria. While Kennedy Jr. claimed he lost 20 pounds in 20 days and felt more mentally clear, he also admitted some of it could be a ‘placebo effect.’

The leader of the MAHA movement reportedly eats steak and fermented vegetables for breakfast and even asks his wife, Cheryl Hines, to carry bags of sauerkraut in her purse when they go out to dinner, according to an interview by the CUT.

However, according to the British Heart Foundation, while some people use the carnivore diet to lose weight quickly, health experts warn that it could cause serious long-term damage to your body.

Does A Carnivorous Diet Aid In Weight Loss?

The carnivore diet works on the principle of ketosis, where the body burns fat for fuel because there are no carbs available. While you might lose weight at first, experts say this is likely because protein makes you feel full, so you naturally eat less. Also because you’ve cut out high-calorie snacks like cake, chips, and alcohol.

However, because the diet is so restrictive, most people find it impossible to stick to for very long. While the all-meat part of his diet is controversial, experts say the fermented foods he eats do have proven benefits.

How Does A Carnivorous Diet Affect Our Health?

The carnivore diet is heavy in red meat and dairy, which are packed with saturated fats. Consuming too much of these fats can lead to:

High Cholesterol

This increases your risk of heart attacks and strokes, as the bad cholesterol or LDL can block arteries and restrict blood flow from organs

High Blood Pressure

Many processed meats (like bacon) are high in salt, which strains your heart. When your salt consumption is high, it causes water retention, which puts pressure on your blood vessel walls, which eventually weakens them.

Kidney Stress

Eating massive amounts of protein forces your kidneys to work much harder to process the waste.

Which can lead to kidney stones, according to National Kidney Foundation.

Kennedy’s diet is much more extreme than the official advice he helped create. He was quick

However, Kennedy Jr.’s personal diet plan is much stricter than the one he helped create for millions of Americans while in office. The official was quick to inform viewers that he is not trying to be a ‘role model’ for everyone, noting that what works for him might not be right for others.

Snacking on grapes could offer surprising protection against heart attacks and strokes, researchers say. The fruit, often labelled a superfood, contains natural compounds that support gut health and help bring down cholesterol levels, both of which play a role in heart disease.

Researchers found that even a short-term change made a difference, especially for people whose diets were low in vegetables and fibre.

Eating Grapes May Lower Heart Attack and Stroke Risk, Study Finds

As per Express UK,In the study, participants saw health improvements after just four weeks of eating grapes daily. The simple dietary shift was linked to a lower risk of cardiovascular disease, which remains the leading cause of death worldwide.

Grapes are rich in antioxidants known to calm inflammation, a key driver of heart problems.

How Grapes Affect Cholesterol and Gut Health

Professor Zhaoping Li of the University of California, Los Angeles, who led the research, said grapes improved the diversity of gut bacteria while also reducing cholesterol levels.

The study followed adults aged 21 to 55 who ate the equivalent of about 40 grapes, or two servings, each day. Their usual diets were low in fibre and plant compounds called polyphenols.

Within a month, researchers saw a clear increase in microbiome diversity. This community of trillions of bacteria plays a central role in digestion, immunity, and overall health.

Drop In ‘Bad’ Cholesterol And Harmful Fats

Participants recorded nearly an eight per cent reduction in LDL cholesterol, often described as the “bad” kind. Levels of bile acids, which fuel harmful fats in the body, fell by more than 40 per cent.

These fats are linked to the formation of clots that can block blood vessels and cut off blood supply to the heart or brain.

Rise in Beneficial Gut Bacteria

One of the most notable changes was an increase in Akkermansia, a beneficial bacterium known to help burn sugar and cholesterol and strengthen the gut lining.

Professor Li said the findings were encouraging, as a healthy gut is increasingly recognised as essential to good overall health.

Why Researchers Call Grapes A Superfood

Professor Li said the study adds to growing evidence of grapes’ heart health benefits, particularly their role in lowering cholesterol. Grapes provide a rich mix of fibre and polyphenols, which appear to influence how the body processes fats.

The findings, published in the journal Nutrients, may help shape future research into diet and disease prevention.

Previous research has linked grapes to a range of health benefits, from helping manage weight gain in middle age to improving libido.

In another study, researchers found grapes may help counter the effects of processed foods high in fats and sugars.

In experiments on mice fed a high-fat Western-style diet, those given a daily grape supplement showed less fatty liver disease and lived longer than those that did not.

Dr John Pezzuto of Western New England University said the results suggest grapes may influence how genes linked to metabolism and ageing behave. The changes observed in mice could equate to several additional years of life in humans.

Researchers also found improvements in brain function. Mice given grape supplements showed better behaviour and cognition, suggesting potential protective effects against conditions such as Alzheimer’s disease.

Grapes and Metabolism

A separate study found grapes may also boost metabolism, helping the body burn calories more efficiently. This could explain their protective role against non-alcoholic fatty liver disease, which is strongly linked to poor diet.

Dr Pezzuto said long-term grape consumption appeared to reduce oxidative damage, improve fat metabolism, and support longevity, even alongside a high-fat diet.

Heart disease kills an estimated 17 million people globally each year and more than 160,000 in the UK alone. While grapes are not a cure, researchers say the evidence suggests they can play a meaningful role as part of a balanced diet.

The findings were published across several journals, including Foods, Antioxidants, and Food & Nutrition, adding to growing interest in how everyday foods influence long-term health.

After NHS doctors warned people against vitamin D tablets and its overdose, Turkish expert Prof Dr Mustafa Atlay, a specialist in endocrinology and metabolic diseases at Ankara Training and Research Hospital, said that vitamin D levels above 100 nanograms per milliliter (ng/ml) pose significant risks. The doctor said, "Excessive and unsupervised intake can lead to toxic effects." He highlighted that while deficiency is common among some people, the best way is sunlight. Most people have a limited sun exposure, particularly indoors workers.

The doctor says that deficiency symptoms include fatigue, muscle weakness, bone pain, and in severe cases osteoporosis. Natural sources of vitamin D include fatty fish, egg yolk, liver, and mushrooms, but diet alone is insufficient. The doctor pointed out that supplements under medical supervision is important, especially for elderly individuals, children, and women.

What Are The Early Signs Of Vitamin D Poisoning?

Atlay noted that early signs of poisoning include:

• High blood calcium
• Causing nausea
• Dehydration
• Kidney injury
• Heart rhythm problems
• Neurological symptoms

What Are The Symptoms NHS Experts Warned About OD-ing on Vitamin D

Vitamin D Overdose: Feeling Frequently Thirsty And Want To Urinate

If you find yourself feeling thirsty or want to urinate more, it could be because you are taking too much of vitamin D. NHS experts suggest to cut the intake to a single 10 microgram tablet and drop any extras if these symptoms appear.

What happens is that excess vitamin D could disrupt fluid and salt balance in the body and thus you may want to visit the loo a little more. Also, keep hydrating yourself. In case the symptoms persist, go to your GP.

Read: NHS Doctors Warn Vitamin D Users About Four Key Overdose Symptoms

Vitamin D Overdose: Burping Constantly, Feel Nausea And Have A Sour Stomach

If you feel like puking, and are burping constantly, for feel like a sour stomach, then try to take your supplement after a meal. If you are taking gummies or spray, it is the best time to switch to a tablet. This happens because food buffers the supplement in the gut and reduces irritation, whereas sprays and gummies contain sweeteners or flavors that could create problems for some people.

Vitamin D Overdose: Bones And Muscles Hurt

If you feel your muscles are cramping more and bones also ache, it is a red flag. The key to this is to prioritize your fluids, mineral -rich foods, and physical activities.

Excess vitamin D could disturb the minerals muscles rely on. Furthermore, dehydration makes cramping worse. You can improve your hydration, drink water with meals and also include yogurt and leafy greens in your food. Include some exercise or gentle stretching in your schedule.

Vitamin D Overdose: Cannot Think Straight

Excess vitamin D could also make your brain fog or cause headaches. So, when you buy any supplement, make sure you read the label. Choose a product listing only cholecalciferol and simple bulking agents. Take it with food at the same time each day to keep intake steady and gentler on the gut. Experts also suggest leaving combined A+D products behind and only pick simple D3 tablet.
