How Safe Is It To Use Microwave For Reheating Food?

Updated Feb 9, 2025 | 09:00 AM IST

SummaryAccording 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.
Microwaving food

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.

Irritable Bowel Syndrome: A Common Yet Underdiagnosed Condition

Updated May 2, 2026 | 09:24 PM IST

Summary​Individuals frequently experience recurrent symptoms such as bloated abdomen, abdominal pain, gas, diarrhea, or constipation, and normalize these symptoms over time or attribute them to "something they ate" or everyday stresses. Therefore, IBS remains undiagnosed for many years.

Irritable Bowel Syndrome (IBS) is a common but often overlooked gastrointestinal disorder; as a result, IBS is very prevalent, with less than 15% being diagnosed.

Individuals frequently experience recurrent symptoms such as bloated abdomen, abdominal pain, gas, diarrhea, or constipation, and normalize these symptoms over time or attribute them to "something they ate" or everyday stresses. Therefore, IBS remains undiagnosed for many years.

Why Diagnosis Is Often Delayed

One reason for this delay in being diagnosed is that the symptoms occur intermittently. It is also important to note that the presentation of these symptoms is inconsistent and unpredictable; there may be episodes where the IBS can last many days, and then completely resolve, thus providing a false sense of relief. Therefore, many individuals choose to delay consulting with a physician due to their belief that the symptoms they are experiencing are not serious.

Stigma Around Digestive Health

Another contributing factor is that there is still a degree of reluctance or discomfort associated with discussing problems related to the gastrointestinal tract openly; this only further complicates under-reporting statistics.

A ‘Functional’ Disorder Adds to Confusion

Finally, IBS is a functional disorder. Therefore, routine diagnostic testing will not reveal any visible abnormalities. Many patients may assume that the symptoms they are experiencing are not "real" or are not significant enough to warrant seeking medical attention, even though the discomfort they experience can be quite significant and affect their daily lives.

If you continually ignore symptoms of IBS, it will hurt your quality of life, productivity, and mental health. If you have persistent discomfort, you are likely to develop anxious feelings about eating, socializing, and travelling. Furthermore, if you don't manage your symptoms, you may experience a combination of untreated IBS with one or more other illnesses that are either gastrointestinal or metabolic; consequently, establishing the correct diagnosis for your IBS will be increasingly difficult as time goes on.

Why Early Action Matters

It is of the utmost importance to identify and respond to early warning signs of IBS as quickly as possible. A thorough evaluation can rule out other illnesses and provide a pathway for appropriate management, including dietary modifications, stress management techniques, and, if necessary, medical treatment.

Once you address your IBS, you will experience better control of your symptoms and eliminate the long-term consequences of IBS, both physically and psychologically.

Colorectal Cancer: UK Surgeon Warns Of 5 Silent Signs You Shouldn’t Ignore

Updated May 2, 2026 | 08:00 PM IST

SummaryThe American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.
Colorectal Cancer: UK Surgeon Warns Of 5 Silent Signs You Shouldn’t Ignore

Colorectal Cancer is not only one of the most common and deadly cancers, but is also one of the most preventable ones.

Unlike many other cancers, patients have a clear window of opportunity to stop it before it even begins. Almost always, these cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.

There is a long interval of time before polyps develop into cancer. During this time, they can be removed if they are identified. If a doctor removes a precancerous polyp during a routine screening, they would not only have nipped the cancer in the bud, but would have also prevented it from occurring.

However, there is a persistent taboo surrounding discussing bowel movements and other risk factors, and public understanding of its symptoms and crucial screening procedures frequently lags.

Dr Jeremy Clark, a consultant general surgeon specializing in colorectal diseases at Nuffield Health in Brighton, has underscored five critical warning signs the public must recognize, The Independent reported.

1. Blood in stool

“Passing blood when you go to the toilet is a worrying feature that you should flag to your GP,” Clark said, adding that the color can vary from bright red to almost black.

“If you see blood in the stools, particularly darker-colored blood or blood that’s actually mixed in with the stools, just once, and it’s significant, that should be reported to your doctor straight away. Don’t wait for that to keep on happening,” he added.

2. Changes in Bowel Habits

Dr. Clark stated that although more constipation may not be a risk factor, any sudden changes in bowel movements that last for a couple of weeks and do not go back to normal must be checked.

“If your bowels go from working once a day like clockwork, and then suddenly you’re going two or three times a day, and the bowels are a bit looser, that’s something that needs to be looked into,” the expert added.

3. Abdominal pain

Dr Clark highlighted that bowel cancers can cause abdominal pain, even in the initial days.

4. Bloatedness

The feeling of being 'quite often’ bloated may also indicate that something is going wrong in the bowel, Dr. Clark said.

5. Unexplained weight loss

Dr Clark said that as these symptoms are common with other conditions, such as hemorrhoids or irritable bowel syndrome (IBS), people often ignore or easily dismiss these symptoms. He urged patients not to ignore and visit their doctor if they notice any of these symptoms.

What Is Colorectal Cancer?

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.

It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.

According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened.

The FIT (Fecal Immunochemical Test) is a simple, non-invasive at-home stool test kit that can collect a small sample of your feces, which can then be tested.

“If it comes back as positive, that means there is blood in your stools which needs to be investigated,” Clark said, adding that the next step is typically the Colonoscopy – the gold standard.

Are Optional Vaccines Really Optional? What Parents Need To Know

Updated May 3, 2026 | 09:00 AM IST

Despite increasing access to healthcare, there is a lack of awareness when it comes to optional vaccines for children. Here, the expert guides parents regarding this. Parents should prioritise their child's health and ensure they are vaccinated without fail. So, learn more about these optional vaccines and make informed health choices when it comes to your children. Vaccines are important for a child’s well-being. Are you aware? In India, childhood vaccines are classified into two categories – those included under the government’s UIP (Universal Immunisation Programme) and those termed as “optional vaccines”.

Dr Amar Bhise, Consultant – PICU (Paediatric Intensive Care Unit), Neonatology and Paediatrics, Motherhood Hospitals, Lullanagar and Kharadi, Pune, spoke about ‘optional vaccines’. The expert also answered FAQs on which vaccines are of utmost importance for children and why timing matters.

What are ‘optional vaccines’?

“Parents should understand that optional vaccines are those that protect against additional infections not covered under the national schedule. These include vaccines for diseases like rotavirus, hepatitis A, chickenpox, influenza, and human papillomavirus. Though labelled optional, many of these vaccines play a crucial role in preventing illnesses that can lead to complications such as severe dehydration from rotavirus, liver inflammation from hepatitis A, and pneumonia or serious flu-related illness from influenza, hospitalisation, or long-term health issues,” said Dr Bhise.

UIP vaccines vs optional vaccines

There is a difference between UIP vaccines and optional vaccines. The reason they are not part of the UIP is often related to cost, prioritisation, and public health logistics, rather than a lack of importance. For example, the rotavirus vaccine helps prevent severe diarrhoea in infants, which can cause hospitalisation. Likewise, the HPV vaccine is important in preventing cervical cancer later in life. These benefits make such vaccines highly valuable, even if they are not universally provided.

Vaccines like the pneumococcal vaccine help prevent serious infections such as meningitis and bloodstream infections, especially in young children. This highlights that “optional” vaccines often protect against conditions that can become severe if left untreated.

Is timing important for vaccinations?

Dr Bhise said that another important aspect parents should consider is timing. Many optional vaccines are age-specific and work best when given within a recommended window. Delaying them may reduce their effectiveness or leave children vulnerable during crucial developmental years.

So, “optional” does not mean they are unnecessary, and it is not advisable to avoid including them in the vaccination schedule. In fact, with changing lifestyles, urban exposure, daycare attendance, and increased travel, children now have higher chances of suffering from serious infections. Vaccines, including influenza vaccines, which need to be taken annually, can help prevent seasonal illness and complications, particularly in young children or those with weak immunity. Chickenpox can cause severe skin infections or pneumonia in some cases, and can disturb parents’ peace of mind. Hepatitis A can affect a child’s overall health.

Parents should not worry, as these vaccines are safe and effective. These vaccines will safeguard children against preventable diseases. Making informed decisions can help parents ensure their child stays healthy.
