Microwaving food

How many of us take advantage of our microwave oven when it comes to reheating leftovers or quickly warming up a meal? It's fast, efficient, and convenient. But, through casual conversations in the kitchen or viral online postings, some of these myths have stuck-or perhaps better, taken root. One of the most common is that operating a microwave might increase the chances of getting cancer. Sound familiar? Let's debunk these myths and let your mind rest easy so that your microwave can continue serving you guilt-free meals!

Perhaps one of the most lingering myths about microwaves is their supposed propensity to cause cancer because they emit radiation. This misconception arises from a fear of the word "radiation" itself. But all radiation is not created equal: microwaves use nonionizing radiation, and it is essentially not the same as nasty ionizing radiation-such as X-rays or gamma rays-and in that respect, it does not have nearly enough energy to knock electrons loose from atoms or break DNA, so it cannot cause cancer.

Microwaves cook food by agitating the water molecules, causing those molecules to eventually produce heat. But whereas boil water cooking would take a pretty long time, microwaves can achieve it in a jiffy. Since regulatory agencies that include the World Health Organization (WHO) and the U.S. Food and Drug Administration (FDA) also did their homework on microwave safety, they have confirmed that microwaves are absolutely safe if you're going to use them the right way to reheat food. So don't worry – your microwave is not a secret health killer.

Does Microwaving Kill Nutrients?

Another extremely widespread misconception is regarding the loss of nutrients in microwaved foods. Though, indeed cooking tends to strip off the nutrients from food items, microwaving happens to be one of the more lenient cooking procedures. As it cooks food quite quickly, requiring minimal water in most cases, microwaving can better retain nutrients than other cooking, such as boiling or frying, which keeps food in contact with heat for a longer duration.

And so, the microwave becomes an unlikely friend towards the preservation of vitamins and minerals in your food-so you can reap in what you have sowed.

Why Microwaves Are Safe and Efficient?

Other than the one myth they coined for canceling cancer, here's why microwaving your food to reheat may be better than stovetop heating:

1. Efficiency: Microwaves heat faster than a stove, saving you time and energy.

2. Uniform Heating: There are no hot spots or burnt edges and rear in microwave ovens.

3. Nutrient Retention: As it has already been discussed above, microwaving appears to be having the potential for retention of more nutrients than the high temperature-based cooking processes.

4. Safety : Unlike stovetop heating where food turns burnt or toxic products can be formed because of high heat, microwaving is safer for reheating.

Of course, not all approaches to microwave application are equal. Always remember to use *microwave-safe containers*—glass or BPA-free plastic are best. Avoid using metal or non-microwave-safe plastics that could leak harmful chemicals into your food.

Busting Popular Myths About Microwaves

Here are some popular myths about microwaves and the truth behind them:

Myth: Microwaves make your food radioactive.

Fact: No, microwaves simply make the water molecules vibrate and generate heat. It doesn't change the molecular structure of your food's molecules or make it radioactive.

Myth: Heating water in a microwave changes its DNA.

Fact: Water does not have DNA, nor does microwaving impact the molecular structure of water enough to kill a plant. This just another viral myth that has no scientific basis.

Myth: There is some truth to the fact that microwave-reradiated food is not as good for you as stovetop-reheated food.

Fact: Actually, microwave reheating can help keep the nutrients better, because the cooking is shorter and at a lower temperature than when stovetop reheating.

How Microwave Myths Harm Our Health

These myths may cause undue stress and confusion about how best to prepare your food safely. Perhaps of greater concern, though, is how myths and misinformation spread in the digital age. Questioning our habits is normal, but in something as important as health and wellness, we need to go by science-proved information only. Your microwave is not the enemy, but it is something that can help restore your hectic, fast life.

The next time someone tries to tell you that heating up your food in a microwave will poison your meal, or strip out the nutrients, call their bluff. Microwaves are safe, efficient, and nutrient-friendly ways to reheat food. In fact, it may have an advantage over conventional cooking. So, have a good leftovers' meal, no worries. You are being smart and healthy!

Is Ozempic Really Better Than A Longevity Diet For Losing Weight? Nutritionist Explains

Updated Dec 7, 2025 | 12:00 AM IST

SummaryA new wave of interest in weight management has pushed both prescription drugs and long-term dietary plans into the spotlight. Among them, Ozempic and the longevity diet stand out for two very different reasons.

Weight loss is one of the most discussed health topics today, with countless strategies promising results. Two approaches that have gained attention recently are the use of Ozempic, a medication designed to regulate appetite and metabolism, and the longevity diet, a mindful, whole-food approach aimed at long-term health benefits. But which is truly more effective for shedding pounds and maintaining overall well-being?

We got in touch with Dr. Pratyaksha Bhardwaj, World Record Holder Dietician and Weight Management Expert, who shared her insights on how both methods work and which might suit different individuals.

What is Ozempic?

Ozempic is a prescription medication that helps regulate appetite by acting on the digestive system and influencing metabolic pathways. Dr. Bhardwaj explains, “Ozempic works quickly because it impacts the hormones that control hunger, making it easier for people to reduce their calorie intake.”

This medication is particularly useful for individuals struggling with obesity, insulin resistance, or difficulty maintaining long-term weight loss. “For people who need rapid results or are starting their weight loss journey, Ozempic can provide a significant boost,” says Dr. Bhardwaj.

However, she also cautions that Ozempic requires medical supervision and carries potential side effects. Without lifestyle changes, there is a risk of regaining weight once the treatment stops.

What is the Longevity Diet?

The longevity diet is a plant-focused way of eating that also includes periods of a fasting-mimicking diet to support long-term health. It encourages meals built around vegetables, fruits, whole grains, legumes, and nuts, while cutting back on red meat, packaged foods, and sugary items. The plan is grounded in scientific research and combines everyday nutritious eating with short stretches of a controlled, low-calorie, fully plant-based diet a few times each year.

As per Everyday Health, the diet centres on mostly plant foods, with plenty of leafy greens, seasonal fruits, whole grains, beans, lentils, nuts, and seeds. Olive oil and other healthy fats are used regularly. Protein comes mainly from plant sources, though a few servings of low-mercury fish may be included each week. It calls for limiting red and processed meats, sweets, and refined grains. Some versions suggest keeping meals within a twelve-hour window, such as between morning and early evening.

Unlike Ozempic, the longevity diet is a long-term, holistic approach to eating. Dr. Bhardwaj describes it as “a diet based on whole foods, mindful eating, timing meals according to your circadian rhythm, and creating sustainable metabolic health.”

While results are slower, the longevity diet promotes cellular integrity, reduces inflammation, balances gut health, and builds lasting healthy habits. “This isn’t a quick fix,” Dr. Bhardwaj notes, “but the benefits extend beyond weight loss, supporting overall health for the long term.”

Which One is Better?

Determining which approach is better depends largely on individual goals, medical history, and lifestyle. According to Dr. Bhardwaj, “Ozempic can provide momentum and jumpstart weight loss, especially for those facing metabolic challenges, but the longevity diet ensures long-term sustainability and better overall health.”

She emphasizes that combining knowledge from both approaches can sometimes be the most effective strategy. “Using Ozempic under medical supervision to get started, while gradually incorporating the principles of a longevity diet, can help people achieve both short-term results and long-term wellness.”

Ultimately, choosing between Ozempic and the longevity diet isn’t about one being universally better than the other, it’s about finding the method that fits your body, lifestyle, and long-term health goals.

Vitamin B12 Deficiency Is Common In Vegetarians, AIIMS Doctor Explains Why

Updated Dec 6, 2025 | 03:00 AM IST

Summary A growing number of studies and clinicians warn that pure vegetarians face a higher risk of vitamin B12 deficiency. Learn why plant-based diets often fall short, the symptoms to watch for, and how simple dietary choices or supplements can protect long-term nerve and blood health.

One of the challenges neurologists are seeing today is the steady rise in patients who show neurological problems tied to low vitamin B12 levels, especially among people who follow a strict vegetarian diet.

Recent findings from several PubMed studies, along with insights from practicing neurologists such as Dr Priyanka Sehrawat, who trained at the All India Institute of Medical Sciences (AIIMS), Delhi, indicate that people who follow a strict vegetarian diet face a much higher risk of developing vitamin B12 deficiency.

Dr Sehrawat explains that plants do not make vitamin B12 because they have no biological need for it, so a purely plant-based diet often falls short. Research also shows that this deficiency affects vegetarians across all age groups, including children, teenagers, adults and older individuals.

Why Vitamin B12 Matters

Vitamin B12 plays several key roles in keeping the body functioning well. It helps the body form healthy red blood cells, which maintain strong haemoglobin levels. It is involved in the repair and formation of DNA, the genetic framework that guides every cell. Just as importantly, it helps build and maintain the myelin coating around nerves, which allows signals to travel smoothly throughout the nervous system.

In a recent Instagram video, Dr Sehrawat highlighted why strict vegetarians rank among the most susceptible. She reiterated that plants cannot produce vitamin B12 at all. As a result, those who rely only on plant foods may not receive enough of this essential nutrient, and over time the body’s reserves begin to decline.

Why Plant-Based Diets Fall Short in Vitamin B12?

The doctor noted that vegan diets are built almost entirely on plant-based foods, which do not naturally contain enough vitamin B12. This nutrient is produced by bacteria that live in animal tissues and certain fermented foods. Although some fortified items exist, they often fall short of daily needs, especially for people with faster metabolisms or digestive problems that affect absorption.

Vitamin B12: Symptoms you Should Watch Out For

Persistent tiredness and weakness

When B12 levels drop, the body struggles to produce enough red blood cells. Reduced oxygen supply to tissues leads to constant fatigue, even after good rest, and a general decline in stamina.

Numbness, tingling or nerve sensitivity

Because B12 supports the maintenance of the myelin sheath, a deficiency may cause unusual sensations, such as tingling, numbness or heightened nerve sensitivity, especially in the hands and feet.

Memory lapses, mood swings or mental fog

Low B12 levels can affect concentration and memory and may contribute to mood changes or a sense of mental dullness.

Pale skin, shortness of breath, slow healing

Anaemia caused by inadequate red blood-cell production may appear as paler-than-usual skin, difficulty catching your breath during activity, or wounds healing more slowly than normal.

Tips On How Vegetarians Can Stay Safe

To prevent this hidden deficiency, vegetarians may consider the following steps:

• Choose fortified items, such as cereals or plant-based milk with added B12

• Add dairy or eggs, if compatible with their dietary preferences

• Use supplements or oral B12 tablets when food sources are limited

• Go for routine blood tests to monitor B12 levels, particularly if symptoms begin to show

Choosing a vegetarian lifestyle can be meaningful and fulfilling, but good nutrition requires attention. Dr Sehrawat’s reminder makes it clear that although plant-based diets have many benefits, they must be paired with reliable B12 sources to prevent a shortage that could affect long-term health.

Vitamin B12 Deficiency: Diagnosis, Symptoms and Treatment Options

Doctors are now seeing more individuals with low B12 levels who come in with unexplained nerve pain, cognitive decline or constant fatigue. The deficiency tends to progress slowly, which means many symptoms only appear after nerve damage has already started.

The doctor added that a simple blood test can detect the deficiency early enough to avoid long-term damage. Since vitamin B12 deficiency is one of the most reversible neurological conditions, timely supplements taken by mouth or through injections can restore levels and protect nerve function. Recovery may take longer if the deficiency is already severe.

On social media, many influencers mix colostrum powder into smoothies and coffees. Podcast ads promote it with big promises such as stronger immunity, better digestion, weight management, and quicker recovery after exercise. A spokesperson for GNC said in an email that interest in colostrum has surged over the past year.

In the company’s “Anti Trend Report,” colostrum was listed as one of the year’s standout supplement trends. Often nicknamed “liquid gold” for its warm golden colour or described as the body’s “starter kit” for newborns, colostrum plays a vital role in early development. The question many adults now ask is whether colostrum supplements are actually good for them.

What Is Colostrum?

Colostrum is the earliest form of milk produced during pregnancy. It develops in the mammary glands and supports a baby’s first line of defence against illness. If you choose to breastfeed, this is the first milk your baby receives. If breastfeeding is not possible or the baby has trouble latching, colostrum can be expressed by hand. It is rich in protein, vitamins, minerals, and antibodies that help build a newborn’s immunity. Cleveland Clinic notes that its deep golden tone and concentrated benefits have earned it the name “liquid gold.”

What Is Colostrum Made Of?

Colostrum contains a high level of protein with very little fat or sugar. It also carries white blood cells that create antibodies. These antibodies help protect a newborn from infections. Even in small amounts, colostrum is dense with nutrients, so a newborn’s stomach needs only a little to gain its benefits.

What Kind of Nutrients Are in Colostrum?

Colostrum offers a wide range of protective nutrients for a newborn. These include:

  • Immunoglobulin A, which is an antibody.
  • Lactoferrin, a protein that helps guard against infections.
  • Leukocytes, which are white blood cells.
  • Epidermal growth factor, a protein that encourages cell growth.
Its colour comes from carotenoids and vitamin A. Vitamin A supports healthy vision, skin, and immunity. Colostrum is also rich in magnesium for heart and bone support, along with copper and zinc, which contribute to immune health.

Are Colostrum Supplements Safe to Use?

Most people can take colostrum supplements without trouble, though they are not right for everyone. There are possible concerns, including allergic reactions in people who are sensitive to dairy, the chance of interfering with immune responses in those with weakened immunity, and digestive issues such as nausea or bloating when taken in larger amounts. MD Anderson Cancer Center advises speaking with a healthcare professional before using colostrum, especially if you have existing medical conditions or are pregnant or breastfeeding.

Who Should Be Cautious?

People with milk allergies: Because colostrum comes from dairy, it can cause allergic reactions and should be avoided.

Immunocompromised individuals: Those with weakened immune systems should discuss it with a doctor, as the immune-active components in colostrum may not be suitable for them.

Pregnant or breastfeeding women: These groups should only use colostrum supplements if a doctor recommends it.

Individuals with dairy intolerance: Anyone who reacts to milk or other dairy products should avoid colostrum as well.
