Ketogenic Diet or Carnivore Diet: Which Diet Is Hurting Your Heart More?

Updated Dec 30, 2024 | 01:03 PM IST

SummaryDiet trends pop up and die off as quickly as they rise to fame. Most of them have a short-term goal in mind like quick weight loss or bulk-up, ignoring how it may affect your body in the long run. Similarly, there has been a lot of debate about two diets, keto and Carnivore.

Amidst the constant stream of diet trends, it's really important to prioritize health over quick fixes. Many people will follow diet trends they find on social media and follow it, ignoring how it may affect their health later in life. While eliminating sugary drinks and processed foods can be beneficial, you must remember that you are cutting out a big chunk of macronutrient groups, which can lead to nutritional deficiencies and health problems. Then we have the carnivore diet, an extreme version of the ketogenic diet, which eliminates carbohydrates entirely, relying solely on animal products for sustenance. This approach raises significant concerns regarding heart health.

Dangers of Zero Carbs

Having a carnivore diet means complete elimination of carbohydrates, even the ones that have proven health benefits. Many animal products consumed on this diet are high in saturated fat and cholesterol and eliminating plant-based foods which are the primary source of fiber, you are hindering the body's ability to regulate cholesterol and blood pressure. This lack of fiber can also negatively impact gut health, which has broader implications for overall well-being.

Increased Risk of Cardiovascular Issues

We all know that high blood pressure, high cholesterol, diabetes, and obesity are known risk factors for heart disease. While the carnivore diet's restriction of sugar and refined carbohydrates may initially prevent blood sugar spikes, the potential for increased saturated fat and cholesterol intake poses a significant threat. Studies show that increased consumption of red meat and poultry can elevate the risk of high blood pressure in people. Similarly, diets high in saturated fat can raise LDL cholesterol levels, further increasing the risk of heart disease. Therefore, the carnivore diet, while potentially leading to short-term weight loss, may significantly compromise long-term cardiovascular health.

Protecting Your Heart Through Dietary Choices

Maintaining heart health doesn't necessitate eliminating meat entirely, but it does require mindful consumption of saturated fat, you must remember that indulging once in a while does not mean you are no longer taking care of yourself, but the end must justify the process, so try eating a controlled amount. Health organizations recommend limiting saturated fat intake to a small percentage of daily calories. This basically translates to a relatively small amount for most individuals.

Beyond Saturated Fat: Other Dietary Considerations

While saturated fat is a cause of concern, there are other dietary factors that play a crucial role in heart health. Added sugar and sodium can also negatively impact cardiovascular well-being, doctors often discourage people from consuming too much of both as they aid in unhealthy weight gain or high blood pressure. Limiting added sugar intake to a small percentage of daily calories is recommended. Similarly, reducing sodium consumption by substituting processed foods with natural alternatives can contribute significantly to heart health.

Embracing a Heart-Healthy Lifestyle

From the research and studies, we understand that having a more balanced diet, which includes fiber-rich foods like nuts, fruits, vegetables, and whole grains is essential for maintaining heart health. Try aiming for a daily intake of at least 30 grams of fiber and you will see how it can significantly benefit cardiovascular function. Another thing that is equally important is incorporating regular physical activity. Finding enjoyable forms of movement, whether it is a social sports or activities you find pleasurable like dancing, can make exercise a sustainable and positive part of a heart-healthy lifestyle, people often find that dragging yourself to places you do not like does not work long term. With this holistic approach of combining a balanced diet with regular exercise, you will get the best protection for long-term cardiovascular well-being.

Eating Unwashed Fruits? Neurologist Says Pesticide Residue May Give You Parkinson's

Updated Apr 26, 2026 | 07:00 AM IST

SummaryPesticide residues, Parkinson’s disease, and what every Indian family should know — without fear, but with awareness.

Every morning across India, fresh fruit finds its way onto the table — mangoes in summer, bananas year-round, grapes, guavas, and more. It remains one of the simplest and most powerful habits for good health. But emerging research is prompting a more nuanced question: not whether we should eat fruit, but how that fruit is grown. Dr Arjun Shah, Consultant Neurologist/Neurophysician, Saifee Hospital, spoke about the risks involved with eating unwashed fruits.

Understanding the Concern: Pesticides and Brain Health

Parkinson's disease is a progressive neurological condition in which dopamine-producing nerve cells in the brain gradually degenerate. This leads to symptoms such as tremors, stiffness, and slowed movement. In India, an estimated 5.8 lakh people are living with the condition, a number expected to rise as the population ages. The causes of Parkinson’s are complex and multifactorial. Genetics, age, and environmental exposures all play a role. Among these, long-term exposure to certain pesticides has drawn increasing scientific attention.

The Chemicals in Question

A number of pesticides have been linked, with varying levels of evidence, to neurological damage and increased Parkinson’s risk in human and animal studies:

  1. Paraquat – Strong evidence; still legal in India
  2. Chlorpyrifos—Moderate evidence of neurological harm; banned in the EU and US, but used in India
  3. Mancozeb / Maneb – Moderate evidence, especially in combination; widely used on fruits like grapes and apples
  4. Endosulfan—Strong evidence; banned in India (2011), but residues persist in soil and food chains
  5. DDT – Moderate evidence; still used in malaria control programmes
  6. Rotenone – Strong evidence in animal models; limited use in India

The concern is not a single meal or occasional exposure. The real issue lies in low-dose, repeated exposure over years, which may quietly accumulate risk. Parkinson’s disease is not caused by one factor alone. Pesticide exposure is just one piece of a much larger puzzle. However, reducing unnecessary exposure is a sensible and low-risk step towards long-term health.

Which Fruits Carry More Residues?

Residue levels often depend on farming practices, but certain patterns are consistently observed. Higher Residue Load (typically thin-skinned or heavily sprayed):

  1. Grapes (table and wine)
  2. Apples (especially imported varieties)
  3. Strawberries
  4. Chillies and capiscum
  5. Pomegranates

Relatively Safer Choices (thick-skinned or locally grown):

  1. Bananas
  2. Papaya
  3. Amla (Indian gooseberry)
  4. Jamun
  5. Guava (local and seasonal)

Practical Steps to Reduce Exposure

For most families, the goal is not perfection but simple, consistent habits that lower risk:

  1. Wash thoroughly under running water for 30–60 seconds — more than just a quick rinse.
  2. Soak before eating in salt water or diluted vinegar for 10–15 minutes.
  3. Peel where possible, especially fruits like apples where residues concentrate on the skin.
  4. Choose local and seasonal produce, which is less likely to have undergone heavy post-harvest treatment.
  5. Opt for organic selectively, especially for high-residue produce like grapes and apples.

The Balanced Perspective

It is important not to lose sight of the bigger picture. Avoiding fruit altogether would do far more harm than good. Fruits are rich in antioxidants and anti-inflammatory compounds that actively support brain health. In fact, locally available options like amla, jamun, and guava are among the most nutrient-dense, neuroprotective foods — affordable, accessible, and deeply rooted in Indian diets. There is no single cause — and no single prevention — for Parkinson’s. But small, informed choices made every day can add up over a lifetime.

Beyond A Pot Belly: Study Claims Beer Has Brain-Boosting Vitamins

Updated Apr 24, 2026 | 09:00 PM IST

SummaryDrinking beer, according to scientists, does have health benefits—but they do not outweigh the downside.

Many people turn to a pint of beer after a busy day at work to unwind and blow off steam, but little do they realise that they might be making their brain healthier in the process. According to scientists, a pint of beer has a host of health benefits to offer - apparently, it has brain-boosting vitamin B6, providing about 15 per cent of your daily requirement. Most of the ingredients used in beer are barley, yeast, and wheat, and these ingredients are sources of vitamin B6. However, just because of some benefits, one must not go on a mindless drinking spree.

Is beer good for your brain?

The study, published in the Journal of Agricultural and Food Chemistry, found some health benefits of beer that deserve recognition and credit, but it did not completely overlook the drawbacks. In fact, the drawbacks outweigh the benefits of drinking beer - beer belly and high blood pressure, for instance. In this study, however, researchers dug deeper into the potential benefits of drinking beer. Some of the key benefits of drinking beer are:

  1. Healthy immune system
  2. Good for the brain
  3. Helps obtain energy from carbohydrates and proteins in food
  4. Helps the body make haemoglobin

What are the dietary sources of vitamin B6?

Vitamin B6 is found in some foods, and in supermarkets, you can also buy foods fortified with vitamin B6. Some of the best dietary sources of vitamin B6 are:

  1. Turkey
  2. Pork
  3. Chicken
  4. Some types of fish
  5. Bananas
  6. Milk
  7. Oats
  8. Peanuts

Which type of beer has high vitamin B6 levels?

The study found that bock beer has the highest levels of vitamin B6 because of its high alcohol content. Following this are wheat beer and other dark beers. Non-alcoholic beers, on the other hand, have ethanol removed after full fermentation and provide higher vitamin B6 levels than those that are made with yeasts that produce less ethanol.

How much vitamin B6 do you need in a day?

Researchers noted that men need about 1.4 mg of vitamin B6 per day and women need 1.2 mg. An average lager can provide 20 per cent of the daily requirement, while a non-alcoholic version can provide about 59 per cent. The research further found that one litre of beer can contain 0.3 to 1 mg of vitamin B6. The study findings, therefore, are only beneficial for people looking to optimise their vitamin B6 intake. Researchers also said that because vitamin B6 is found in abundance in food sources, there is almost no need for one to turn to beer for this purpose.

Especially for people dealing with certain health issues, such as chronic kidney disease or alcoholism, beer must not be relied upon to increase vitamin intake. Instead, it is important to focus on other sources of B vitamins like B12 or B2, which are found in abundance in animal foods and dairy products. These foods can also help you absorb energy better from food and play a role in metabolism. People who are vegan can opt for other fortified substitutes to meet their nutritional requirements.

Can Healthy Foods Increase Lung Cancer Risk? New Study Raises Concerns

Updated Apr 23, 2026 | 12:00 AM IST

Fruits and vegetables are widely recommended to improve health and reduce the risk of cancer and other diseases. However, a new study claimed that eating a very healthy diet—packed with fruits, vegetables, and whole grains—can raise the risk of lung cancer.

Shockingly, the study showed that the risk of lung cancer with a healthy diet may be higher in younger non-smokers.

The research from the University of Southern California, presented at the annual meeting of the American Association for Cancer Research, found that patients under 50 diagnosed with lung cancer often had better-than-average diets.

The experts zeroed in on the culprit—pesticide exposure from conventionally grown produce.

"Our research shows that younger non-smokers who eat a higher quantity of healthy foods than the general population are more likely to develop lung cancer," said lead investigator Jorge Nieva, a medical oncologist and lung cancer specialist with USC.

"These counter-intuitive findings raise important questions about an unknown environmental risk factor for lung cancer related to otherwise beneficial food that needs to be addressed," Nieva added.

Pesticides In Healthy Foods — A Hidden Risk

According to the researchers, the reason may lie in environmental exposure, particularly pesticides used in agriculture. Nieva noted that commercially produced (non-organic) fruits, vegetables, and whole grains are more likely to carry higher levels of pesticide residue compared to dairy, meat, and many processed foods.

He also pointed out that agricultural workers who are regularly exposed to pesticides tend to have higher rates of lung cancer, which supports the possibility of a connection.

The study also found that young women who do not smoke are diagnosed with lung cancer more often than men in the same age group. Women in the study also tended to consume more fruits, vegetables, and whole grains than men.

What Is Lung Cancer?

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.

Traditionally, lung cancer occurs in older people. However, non-smokers age 50 and younger, particularly women, are now experiencing increasing rates of lung cancer and are more likely than men to develop the disease.

In many cases, there are no symptoms; however, one must look out for these:

  • a persistent cough
  • coughing up blood
  • persistent breathlessness
  • unexplained tiredness and weight loss
  • an ache or pain when breathing or coughing.

Why More Research Needed

Nieva emphasized that more research is needed to confirm any link between pesticide exposure and lung cancer in younger people, especially women.

In this study, researchers did not directly measure pesticide levels in the foods participants ate. Instead, they estimated exposure using existing data on average pesticide levels in food categories such as fruits, vegetables, and grains.
