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!

While matcha has become a favourite for many, it comes with its own set of benefits and cautions. Celebrated for its energising properties and health perks, matcha is not completely risk-free. Overdoing it can lead to certain health issues. Recent research suggests that excessive matcha consumption can affect the heart and digestion. We spoke to Dr. Rahul Mehrotra, Chief - NIC & Clinical Cardiology, Artemis Hospitals, to understand more.

How Overconsumption of Matcha Can Impact Your Heart or Health?

Matcha, the finely powdered green tea, is rich in antioxidants, especially catechins and is popular for its potential health benefits. But as with most superfoods, moderation is essential. Drinking more than 2–3 cups a day may lead to issues, particularly for heart and digestive health.

Matcha contains caffeine, and consuming it in large amounts can increase heart rate, cause palpitations, raise blood pressure, or trigger anxiety in sensitive individuals. While L-theanine in matcha usually has calming effects, too much caffeine can overpower this balance.

Digestively, matcha is slightly acidic. Overconsumption can lead to stomach upset, acid reflux, or constipation, especially on an empty stomach. Additionally, matcha can interfere with iron absorption from plant-based foods, potentially raising the risk of iron deficiency over time if your diet isn’t balanced.

While matcha offers notable benefits such as improved metabolism and focus, taking too much may offset these advantages. The best approach is moderate consumption as part of a balanced diet.

Benefits of Moderate Matcha Consumption

When enjoyed in moderation, matcha can be a healthful addition to your daily routine. Here are some of the main benefits:

  • Sustained Energy Boost: Matcha provides a smooth, long-lasting energy lift without the jitters of coffee, thanks to the combination of caffeine and L-theanine. This helps maintain steady energy throughout the day.
  • Rich in Antioxidants: Packed with catechins, matcha helps neutralise harmful free radicals, supports overall wellness, and can promote liver health.
  • Enhanced Focus and Relaxation: L-theanine in matcha encourages calmness while enhancing concentration, making it an excellent drink for mental clarity.
  • Boosts Metabolism: Regular matcha consumption may help improve metabolism and support fat burning, assisting with weight management when paired with a healthy lifestyle.
  • Supports Heart Health: Drinking matcha regularly may aid in regulating blood sugar, reducing blood pressure, and lowering bad cholesterol, all of which contribute to heart health.

According to Dr. Rahul Mehrotra, enjoying matcha sensibly allows you to harness its benefits without risking adverse effects on your heart or digestion.

How Much Matcha Should You Consume?

When it comes to drinking matcha, moderation is essential. Here are some general guidelines for safe consumption:

  • One to Two Cups Per Day: Most experts suggest limiting matcha to one or two cups daily.
  • Caffeine Limit: Make sure your total caffeine intake—from matcha and other sources—does not exceed 400 milligrams per day.
  • Pregnant Women: Expecting mothers should be careful with matcha and other caffeinated drinks to avoid potential complications.
  • Caffeine Sensitivity: If you are sensitive to caffeine, it’s wise to reduce your matcha intake to prevent side effects like jitteriness or palpitations.
  • Age and Health Considerations: Older adults or people with conditions such as high blood pressure should check with a doctor before increasing their matcha consumption.

Those with higher caffeine tolerance might handle more matcha without issues, while younger individuals or those with underlying conditions, such as liver problems or high blood pressure should approach it with extra caution.

MCT oil has become a popular supplement in the world of health and wellness, often praised for its ability to boost energy, support weight management, and improve brain function. Derived from medium-chain triglycerides, fats that are more easily digested and converted into energy than long-chain fats.

Whether you are an athlete, someone looking to support cognitive health, or simply exploring healthier fat options, understanding what MCT oil is, how to use it, and why it has gained so much attention can help you decide if it belongs in your daily routine.

What Is MCT Oil?Medium-chain triglyceride (MCT) oil is a processed oil typically derived from coconut or palm kernel oil, though small amounts of MCTs are also naturally present in foods like dairy. As the name suggests, MCT oil contains medium-length chains of fats called triglycerides. Because these fatty acids are shorter than the long-chain fats found in many other foods, the body can digest and convert them into energy more quickly.

There are four main types of medium-chain fatty acids: lauric acid, caproic acid, caprylic acid, and capric acid. MCT oil is made up almost entirely of caprylic and capric acids, which are thought to be the most easily absorbed and metabolised by the body.

MCT oil is versatile and easy to add to your daily routine, but it’s best to start small to see how your body responds. Begin with 1 teaspoon a day and gradually increase to 1–2 tablespoons if tolerated. Here are some simple ways to use it:

  • In your morning coffee or tea: Blend it in for a creamy texture and sustained energy.
  • Smoothies and shakes: Add a spoonful for an extra boost of healthy fats.
  • Salad dressings or sauces: Use it as a light base or mix with olive oil.
  • Cooking: MCT oil has a low smoke point, so it’s best for drizzling over foods rather than frying or high-heat cooking.
Because it’s quickly absorbed, some people may experience stomach discomfort if they take too much at once. Starting slow is the key.

Why Is MCT Oil Getting So Popular?

MCT oil has surged in popularity because of its reputation as a quick and efficient source of energy and its potential health benefits. Unlike longer-chain fats, MCTs are rapidly absorbed by the body and converted into fuel, making them a favorite among athletes, busy professionals, and anyone looking for an energy boost.

Additionally, studies suggest that MCT oil may support weight management, improve mental clarity, and even aid digestion. It is is easy to add to coffee, smoothies, or salad dressings which also makes it an attractive option for those seeking a simple way to incorporate healthy fats into their diet.

MCT Oil: Benefits

Research suggests MCT oil may support weight management, improve cognitive function, and provide a quick source of energy since it is metabolized faster than other fats. Some studies also point to its role in reducing risk factors for heart disease and aiding people with digestive issues who struggle to absorb fats. For example, a 16-week clinical trial published in the American Journal of Clinical Nutrition found that participants using MCT oil lost more body weight compared to those using olive oil.

While MCT oil is not a magic fix, it can be a useful addition to a balanced diet when taken in moderation. Its potential benefits for energy, metabolism, and brain health make it popular among health enthusiasts, but it is important to consult a doctor before making it a regular part of your routine. Choosing high-quality MCT oil and using it wisely can help you enjoy its advantages without unwanted side effects.

Taking care of our brains should be a top health priority. After all, the brain controls nearly every function in our body. As we age, however, our brain function naturally declines, and the risk of dementia rises. Dementia is a term that covers memory loss and other cognitive difficulties that significantly affect daily life. Current data suggest that the number of dementia cases—now around 514,000 per year, could double by 2060, highlighting the urgent need for ways to protect the brain.

Research shows that lifestyle choices have a major impact on brain health. But did you know that certain diets can help lower your risk of Alzheimer’s? Here’s what you need to know.

What is Mediterranean Diet?

The Mediterranean diet is a plant-focused way of eating, inspired by the traditional diets of Mediterranean countries. It emphasizes fresh fruits and vegetables, whole grains, legumes, nuts, seeds, and olive oil as the main source of fat. The diet includes moderate amounts of fish and dairy while limiting red meat and sweets. Beyond what’s on the plate, it also encourages lifestyle habits such as regular physical activity and sharing meals with others, which supports social connections and helps reduce stress.

Mediterranean Diet Could Lower Alzheimer’s Risk by 35%

A long-term study conducted by the Nurses’ Health Study (NHS), which followed female nurses from 1989 to 2023, found that people who closely followed the Mediterranean diet over the years had a significantly lower risk of dementia and better cognitive function. This protective effect was particularly evident in individuals with varying genetic risk for Alzheimer’s, including carriers of the APOE-e4 gene. Similar findings were also observed in the male Health Professionals Study.

While the Mediterranean diet as a whole was linked to reduced dementia risk, researchers highlighted a few key components that seem to have the most impact: fresh fruits, nuts, and sources of monounsaturated fats, such as olive oil and avocados.

The study indicates that sticking to the Mediterranean diet over the long term may substantially lower the risk of Alzheimer’s, even for those with a genetic predisposition. This diet is packed with fiber, antioxidants, healthy fats, and lean proteins, found in foods like fruits, vegetables, nuts, seeds, legumes, whole grains, seafood, and olive oil. Incorporating more of these foods into your daily meals can be a simple way to support brain health.

How To Follow a Mediterranean Diet?Incorporating the Mediterranean diet into your daily routine doesn’t have to be complicated. Start by adding more fresh fruits and vegetables to every meal, swapping refined grains for whole grains, and including nuts, seeds, and legumes as snacks or salad toppings. Use olive oil as your main cooking fat instead of butter or processed oils, and aim to include fish or seafood a few times a week.

Red meat and sweets can be enjoyed occasionally, rather than daily. Beyond food, try to stay active through walking, yoga, or other forms of exercise, and make mealtimes a social experience whenever possible, sharing meals with family or friends to combine nutrition with connection and reduced stress.

For personalised guidance, consulting a registered dietitian can help you create a plan that fits your tastes and lifestyle.
