Microwaves are a common appliance in every household now. You will see it in kitchens of not just houses, but offices, cafeterias, and co working space. However, there are studies that show that heating food in a microwave could be a health concern. While it does come handy, there are questions about harmful radiation and nutrient loss and heating safety that still linger.

Does Microwave Destroy The Nutrients In Food While Heating?

Some research suggests that microwaving may cause nutritional loss, particularly in vegetables. For example, studies have shown that microwaving broccoli with water diminishes its flavonoid content, which are anti-inflammatory compounds. However, experts note that cooking method and duration have a significant influence on nutrient retention.

Surprisingly, several studies indicate that microwaving preserves more nutrients than traditional cooking methods. A study comparing microwaved versus oven-cooked ready meals found that the microwaved version contained somewhat more vitamin C. Another study discovered that microwaving some vegetables, such as broccoli and green beans, may retain more beneficial compounds than boiling.

Ultimately, the nutrient loss really vary on the type of food which is being heated and how it is being cooked. Experts also recommend using minimal water and shorter cooking times to maximize the nutrient retention.

Is Heating In Plastic Safe?

Plastic containers and heating food in it, has always been a topic of debate. While containers do come with microwave-safe stamps, is it really safe to heat them with food?

According to research, when certain plastics are subjected to heat, they produce compounds such as phthalates and bisphenol A (BPA). These substances have been associated to hormonal disturbance, metabolic problems, and perhaps reproductive concerns.

A study also took in account over 400 plastic food containers that were microwave-safe and found that most of them leaked hormone-disrupting chemicals. These are phthalates, warn experts, which are commonly used in food packaging and can interfere with body's hormonal balance, and increase risk of diabetes or even high blood pressure.

Additionally, BPA exposure has been associated with fertility issues and immune system disruptions.

So, what can be done instead?

To minimize this risk, experts recommend using glass or ceramic container when microwaving foods. If you must use a plastic container, make sure the container is not damaged or old, as they are more prone to leach harmful chemicals.

What About The Radiation?

Concerns about microwave radiation have been largely debunked by decades of research. Microwaves use non-ionizing radiation, which does not have enough energy to damage DNA or cause cancer. The electromagnetic waves used in microwaves are similar to those from radios and light bulbs.

Experts emphasize that microwave ovens are designed to contain radiation, preventing exposure. As long as the microwave is in good condition and the door seals properly, there is no significant health risk from microwave radiation.

Other Concerns

Microwaving food could sometimes also lead to uneven cooking and it can create some risks to food safety. Thus, experts advertise to use microwave only to reheat the food and not to actually cook raw food. For safe reheating, food should reach at least 82°C (176°F) throughout to kill bacteria.

People who are prescribed a widely used medication are being advised to contact a doctor if they notice certain symptoms. As per Mirror, health officials say these “serious” side effects should not be delayed or ignored and may need medical review sooner rather than later. Diltiazem is a drug commonly given to manage high blood pressure. It is also sold under brand names such as Adizem, Angitil, Tildiem, Viazem, and Zemtard.

Doctors prescribe it to people with high blood pressure to lower the risk of coronary heart disease, heart attacks, and strokes. The medicine helps by reducing blood pressure and allowing the heart to pump blood more easily through the body. However, new warnings linked to the drug have now been highlighted.

What Is Diltiazem?

Diltiazem belongs to a group of medicines called calcium channel blockers. It is used to treat high blood pressure, long-term stable angina, which causes chest pain, and certain types of irregular heartbeats. The drug works by relaxing blood vessels and easing the strain on the heart. According to Medline Plus, common side effects may include dizziness, headaches, swelling, and a slower heart rate. It is mainly prescribed for hypertension, angina, and heart rhythm conditions such as atrial fibrillation. In some cases, it is also used in cream form to help treat anal fissures.

The NHS website also states that diltiazem may be used to:

• Prevent chest pain linked to angina
• Lower the number of attacks in people with Raynaud’s phenomenon
• Support the healing of an anal fissure

Like most medicines, diltiazem can cause side effects, although many people may not experience any. The NHS notes that there are several “common” side effects patients should be aware of.

Diltiazem Common Side Effects

These effects are seen in more than one in 100 people. The NHS explains: “They are usually mild and do not last long. There are ways to help manage them.”

They include:

• Swelling in the hands, ankles, or feet
• Headaches
• Dizziness or feeling light-headed
• Feeling tired, weak, or generally unwell
• Feeling hot, flushed, or noticing redness of the skin
• Itching or a burning feeling on the skin where the cream or ointment is applied
• Stomach discomfort
• Indigestion
• Constipation

The NHS adds: “Talk to a doctor or pharmacist if coping advice does not help, or if a side effect continues or becomes troublesome.”

Diltiazem Serious Side Effects

In rare cases, diltiazem may lead to “serious side effects.” These are reported in fewer than one in 10,000 people.

According to the NHS, you should “stop taking diltiazem and contact a doctor or call 111 immediately” if:

• You experience severe stomach pain
• The whites of your eyes or your skin turn yellow, which may be harder to notice on brown or black skin and could point to liver problems
• You become aware of your heartbeat or notice palpitations

You should also call 999 or go straight to A&E if you have chest pain that does not ease after a few minutes, or if chest pain is new or worse than usual when you already have angina. This may indicate a heart attack and requires urgent medical attention.

Before "brain health" became a buzzword, Rudolph E Tanzi started to write the science behind it. Tanzi is a neurology professor at the Harvard, and co-director of the Henry and Allison McCance Center for Brain Health at Massachusetts General Hospital is known for discovering three key Alzheimer's genes. In his 46-year career, he wrote hundreds of journal articles that helped in shaping the modern understanding of neurodegenerative illness.

In 2023, neuroscientist also teamed up with holistic health advocate Deepak Chopra to write Super Brain, a book that pushed against the idea that brain has fixed limits. The belief also sits at the heart of SHIELD, which a lifestyle framework developed by Tanzi to protect long-term brain health. It focuses on six pillars:

• Sleep
• Handling stress
• Interaction with others
• Exercise
• Learning
• Diet

Tanzi now 67, says these principles are not just theoretical, but he credits his own research and daily habits for helping him stay mentally sharp, physically active and deeply engaged in his work.

“I’m doing more work and having more fun and excitement than ever,” he says. “Your world can feel young or stagnant based entirely on the health of your brain. Most people do not realize that.”

Let us look deeper into SHIELD:

Sleep

Tanzi aims for seven to eight hours of quality sleep each night. Sleep, he explains, is not just rest. It is active maintenance for the brain.

During deep sleep, the brain clears out toxins, including amyloid proteins that are linked to Alzheimer’s disease years before symptoms appear. Each deep sleep cycle works like a rinse for the brain.

Rather than following a fixed bedtime, Tanzi plans backward from his wake-up time to ensure at least seven hours of sleep. An hour before bed, screens go off and phone scrolling stops. If sleep falls short, he recommends short power naps, even brief ones.

Handling stress

Chronic stress is one of the biggest threats to brain health. It raises cortisol levels, which Tanzi describes as toxic to the brain over time.

He believes modern life has amplified stress through constant notifications, emails and social media. His primary tool to counter this is meditation, especially practices that quiet the constant internal chatter many people experience.

Tanzi suggests closing your eyes periodically during the day and focusing on images rather than words. Let thoughts come and go without turning them into sentences. He also warns against living mentally in the past or worrying excessively about the future instead of staying present.

Reducing this internal noise, he says, boosts creativity, intuition and mental clarity.

Interaction with friends

Social connection matters more than many people realize. Loneliness has been linked to a higher risk of cognitive decline.

The key, Tanzi says, is interacting with people you genuinely enjoy. Stressful social interactions do not count. Even regular texting or phone calls can help.

Because many of his friends live far away, Tanzi stays connected through small, intentional check-ins with different friend groups each day. Used this way, social media can actually support brain health instead of draining it.

Exercise

Regular movement improves blood flow to the brain and helps form new nerve cells, particularly in areas affected early by Alzheimer’s disease. Exercise also releases hormones that help break down harmful amyloid buildup.

Tanzi cycles on a stationary bike for 30 minutes every other day and walks on alternate days. He points to research showing that even modest increases in daily steps can meaningfully reduce dementia risk.

Learning new things

Learning builds new synapses, the connections that store memories and support thinking. When these connections weaken, cognition suffers.

As people age, Tanzi says they often become less adventurous and rely on the same mental patterns. That stagnation harms the brain.

To counter this, he constantly learns new music on the keyboard, writes his own compositions, reads widely and watches documentaries. New experiences keep the brain flexible and resilient.

Diet

Diet plays a central role in brain health, largely through the gut microbiome. When gut bacteria are balanced, they produce compounds that reduce inflammation and help clear amyloid from the brain.

Tanzi follows a Mediterranean-style diet rich in fruits, vegetables, olive oil, nuts and seeds. He is mostly vegan but not rigid. His snacks tend to be crunchy whole foods that gut bacteria thrive on.

He is also increasingly focused on environmental factors that affect the brain. His upcoming book will explore what he calls the “killer P’s,” including plastics, pollution, periodontal bacteria and processed foods, and how they quietly shape long-term brain health.

Deadly Nipah Virus Outbreak: Nipah virus outbreak reported in West Bengal, India started with the cases of two nurses, one of whom is in "critical condition". Nearly 100 people are quarantined, and India's Ministry of Health shared precautions to prevent Nipah virus infection in a post on X.

However, how did it all start?

Nipah Virus: The Evolution And Where It All Began

The original infection was first identified in September 1998 in Perak, Malaysia, which was followed by second and third clusters in the state of Negri Sembilan, notes a 2021 study that tracks the evolution of the virus. The cases were prominent in adult men who were in contact with swine. By March 1999, a cluster of 11 similar cases were identified in Singapore, mostly common in slaughterhouse workers, who were in contact with pigs imported from Malaysia. This is how the virus started to become global. While people there were isolated, the outbreak in Malaysia continued to spread. This led to restrictions on swine imports to Singapore, followed by nationwide testing among pigs in Malaysia, and ultimately mass culling of over one million pigs from any farm in Malaysia with a confirmed infection.

Then appeared a new, distinct strain of Nipah virus with infection which was characterized largely by severe respiratory symptoms. In 2000-2001, Bangladesh and India were affected. Epidemiological studies revealed clustering around household members and hospital contacts without any clear animal exposure. This raised suspicion for human to human transmission.

Nipah Virus In Bats: How Did Scientists Know?

When Nipah virus (NiV) was first identified, scientists noted that the closely related Hendra virus persisted in fruit bats of the Pteropus genus, raising early suspicions that these bats could also be the natural reservoir for NiV. Later research confirmed the presence of NiV genetic material and neutralising antibodies in urine, saliva, blood and various organs of several Pteropus bat species across Asia, including in countries with no recorded human cases.

This raised doubts, and it was later revealed that due to the consumption of raw date palm juice, the infection developed. This is because bats also are carrier of the virus and they may bite into raw fruits or lick them, and consuming juice from such fruits could spread the infection. This was a common practice in Bangladesh and much of South Asia.

Studies examining human exposure patterns found a strong link between NiV infection and the consumption of raw date palm sap. The sap, typically harvested between December and February, is often contaminated by bats that feed on it, leaving behind saliva and urine. In Bangladesh, this route has been identified as the main pathway of transmission from bats to humans, although the possibility of additional human-to-human spread remains.

Nipah Virus Went Global

In 2014, a serious outbreak of illness hit two villages in southern Philippines, with people developing brain infections, meningitis and flu-like symptoms. Tests later confirmed Nipah virus as the cause. Among those who developed acute brain infection, the death rate was extremely high at 82 percent. While some infections spread from person to person, this was the first outbreak linked to the slaughter of horses and the consumption of horse meat. Around the same time, several horses and other domestic animals that had eaten horse meat also fell sick and died.

In 2018, another outbreak occurred in Kerala, India, where 23 confirmed and suspected cases were reported. The virus spread across three hospitals, with both primary and secondary infections traced back to one initial patient. Samples collected from the patient’s home and workplaces, including pets and partially eaten fruits dropped by bats, all tested negative for the virus, and the exact source of the infection could not be identified.

Nipah Virus Outbreak In India's West Bengal

Currently, two nurses, a doctor, hospital staff and some patients have reported to be infected by the virus. A survey conducted on bats in West Bengal found no active Nipah virus infection. Though there were antibodies detected in one specimen, which indicated prior exposure. This was confirmed by a senior state forest department official. The survey was conducted amid the identification of two confirmed Nipah virus cases.

To conduct the survey, nine bats near Kuberpur on the Kolkata-Barasat Road in Madhyamgram were tested using RT-PCR. All samples were negative, however, one bat, tested positive for antibodies. However, it only suggested prior infection, meaning there was no current risk of transmission.

The survey was conducted by the state forest department in collaboration with scientists form Pune-based National Institute of Virology. "The findings are reassuring, but caution is warranted. Surveillance and prevent measures will continue until we are fully assured that there is no risk," confirmed a senior official of the West Bengal Health Department.

Nipah Virus: What Is It And What Are The Symptoms?

As per the World Health Organization (WHO), Nipah virus infection is a zoonotic illness that is transmitted to people from animals, and can also be transmitted through contaminated food or directly from person to person.

In infected people, it causes a range of illnesses from asymptomatic (subclinical) infection to acute respiratory illness and fatal encephalitis. The virus can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.

Although Nipah virus has caused only a few known outbreaks in Asia, it infects a wide range of animals and causes severe disease and death in people.

Nipah Virus Symptoms

• Fever
• Headache
• Breathing difficulties
• Cough and sore throat
• Diarrhea
• Vomiting
• Muscle pain and severe weakness
