re you fond of eating meat? Do you enjoy flavorful mutton curry and spicy kebabs? If so, you are certainly not alone. Red meat, such as mutton, is a popular part of many Indian diets.
Although in recent years, there has been a growing concern, is red meat really bad for the heart?
A fresh review in the
American Journal of Clinical Nutrition
has again stoked controversy surrounding red meat and heart health and this time raised questions about how research funding can affect outcomes. Conducted by Dr. Miguel López Moreno and his team from Spain's Francisco de Vitoria University, the analysis reviewed 44 clinical trials spanning more than four decades and found a clear trend: studies with financial support from meat industry groups were nearly four times more likely to report favorable or neutral outcomes on heart health compared to independently funded research.
Industry-unaffiliated studies—those funded by academic institutions, government grants, or non-profit organizations—also consistently reported either unfavorable or neutral cardiovascular impacts. Researchers attribute the discrepancy to the study design. Industry-sponsored studies tended to compare red meat to other less nutritious foods, like refined carbohydrates or other animal proteins, whereas independent studies compared red meat to a broader set of heart-healthy foods like legumes, soy products, and nuts.

Although others contend that moderate intake of other protein sources is a component of an overall balanced diet, nutrition researchers point out that plant-based proteins repeatedly have more positive results for cardiovascular health. The problem also speaks to the larger challenge of underfunded nutrition research in the United States. With fewer than 5 percent of the National Institutes of Health budget dedicated to nutrition research, experts suggest that dependence on industry-sponsored studies could grow.
What are the traditional beliefs?
A comprehensive study conducted by researchers of the
University of Oxford's Nuffield Department of Population Health
has established a clear link between the consumption of red and processed meats and an increased risk of coronary heart disease (CHD). This study constituted over 1.4 million participants, and their findings were quite clear: 50 grams of processed meat daily increases the risk of coronary heart disease by 18%. Even unprocessed meat can lead to a 9% higher risk of heart disease.
However, poultry consumers, good news for you: this study showed no significant association with CHD risk.
It is believed that red and processed meat's high saturated fat and sodium levels are the primary reason for these heart-related concerns. Sodium causes high blood pressure, and saturated fats increase bad cholesterol levels, both of which are major causes of heart disease. What this study suggests is that if you are ready to cut back on red meat consumption, it could significantly lower the rates of cardiovascular death.
A systematic review and meta-analysis published in the
European Heart Journal in 2023
provides a significant insight into the relationship between red meat consumption and the risk of cardiovascular disease. According to this, a 50-gram daily increase in processed meat consumption correlated with a 26% higher risk of cardiovascular diseases. Each 100 grams of unprocessed red meat intake was associated with an 11% higher risk of CVD.
According to this research, Western diets showed slightly higher risks due to greater meat consumption and lower intake of fiber-rich vegetables.
Eastern diets that include more legumes, whole grains, and plant-based ingredients showed less pronounced risks.
Should you stop eating red meat altogether?
It is important to understand that everything you consume should be done in moderation. Red meat is not inherently evil; it is a rich source of essential nutrients like zinc, protein, and Vitamin B12, which are especially important to diets where nutrient deficiencies are common. The problem only arises when red meat is consumed frequently, in large quantities, or in heavily processed forms like frozen meat patties.
Replacing red meat occasionally with plant-based proteins, whole grains, and vegetables not only reduces health risks but also keeps your meals flavorful and satisfying. Regional diets across India already embraced this culture long ago; think of delectable south Indian sambar or a hearty north Indian Chickpea curry with rice. A healthier heart begins with what is on your plate.
In the end, it's all about what your eating habits are, how well you sleep, and how often you work out; all of it contributes some significant portion to your heart health. Heart diseases are influenced by multiple factors, but diet remains one of the most modifiable and powerful tools in prevention.

Overlapping symptoms make Cov diagnosis difficult without tests
Kolkata: The overriding symptoms of Covid during the current surge were a low-grade, persistent fever, along with a mild cough, which could be deceptive, warned doctors. While it made a vast majority ignore the symptoms and take over-the-counter medicines, for some, the fever refused to subside. It was the continuing fever that led many to consult physicians. Most of those testing Covid positive on admission to hospitals for other ailments were also screened at hospitals due to their fever. Covid cases have been rising in Bengal over the past week. The state logged 319 cases in the past seven days, taking the number of active cases to 331 on Monday. Unlike the first three waves, when Covid came with loss of smell and taste, accompanied by high fever, severe cough and pneumonia, the symptoms of the current spike were muted and flu-like, said doctors. With a runny nose and a sore throat, symptoms in most were milder than that during the pandemic, said CMRI pulmonology director Raja Dhar. "Mild symptoms led many to ignore it, which could be risky at a time, when cases are proliferating. One should get tested, and if the result turns positive, the patient should isolate, especially if there are elders in the family. Screening should be stricter for elderly people with comorbidities, and if the fever and cough persist beyond four to five days, hospitalization is advised as symptoms could worsen quickly," said Dhar. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Beyond Text Generation: An AI Tool That Helps You Write Better Grammarly Install Now Undo CMRI has seven Covid patients admitted. Manipal Hospitals infectious diseases physician Sayan Chakrabarty agreed. "The symptoms are flu-like, but for some, the fever persists. Those patients are getting tested, and many tested positive. While severe cases have been rare so far, rising numbers could lead to a spurt," he added. Five Covid patients, admitted to Manipal's different units, have been discharged. Covid pneumonia has been rare this time, said Charnock Hospital pulmonologist Soumya Sengupta. "Most patients have a cough and low fever. Even the elders in hospital who tested positive have muted Covid symptoms. Most are being treated for their comorbidities. During the pandemic, a vast majority of senior citizens had severe Covid symptoms, including pneumonia," said Sengupta. Dhar pointed out that the Jn.1 variant of the Omicron, now believed to be in circulation, was highly transmissible though less virulent. "But it is safe to isolate yourself for five days on testing positive and take symptomatic drugs. Symptoms are likely to remain mild till this wave blows over in about a fortnight. But even mild Covid may aggravate comorbidities, especially those related to lungs," he said.

In New York, Khalistan backers heckle doctor who aided 2020-21 farm stir; Dr Swaiman says he is proud of Indian roots, Tricolour
Bathinda: Dr Swaiman Singh, who played a vital role during the 2020-21 farm stir on Delhi borders, was heckled by pro-Khalistan individuals at a gurdwara in New York on Sunday afternoon. The pro-Khalistan elements were angry because he displayed the Indian tricolour during the farmers' protest. The show of resentment came just days ahead of Sikhs across the world remembering those who were killed in Indian Army's Operation Bluestar at Golden Temple on June 6, 1984. Despite the opposition, Dr Swaiman stood his ground and delivered a speech for which he was invited by New York Sikh Cultural Society. A large congregation was held at the NY Sikh Cultural Society Gurdwara on Sunday afternoon (early hours of Monday in India). Dr Swaiman and former New York governor Andrew Mark Cuomo were invited by the society to deliver a lecture. Undeterred, Dr Swaiman delivered his response, challenging the group to open dialogue. Speaking to TOI over the phone from the US, Dr Swaiman said it was true that Sikhs living in various parts of the world were angry over the way their revered religious place was attacked by the govt in 1984, and how justice had not been delivered till now. "But, being an Indian, I have displayed the tricolour a number of times, and I am proud of it. Whatever happened in 1984 was an attack by a govt of a particular political party, it does not denote all of India. We may be angry with the govt or party, but not with India," he said. Dr Swaiman added he too had been branded a "Khalistani" in the past and this was not right. "ThzZ country should look into the grievances of Sikhs and deliver justice. But, just some people opposing me cannot undermine my commitment the people of my nation, where my team is regularly working," he added. The NY Sikh Cultural Society Gurdwara remains a vital community hub, fostering dialogue and cultural unity. "This incident highlights the need for constructive conversations to bridge divides within our communities," he said. Dr Swaiman's family belongs to Tarn Taran district in Punjab. During the farm struggle, his organisation, '5 Rivers Heart Association', held medical camps at the protest site to help the protesters.

New Covid vaccine developed by USA researchers is ready to fight Coronavirus. How effective it is?
Amid fresh surge in Covid-19 cases, a team of US researchers has developed a new type of mRNA vaccine that is more scalable and adaptable to tackle continuously evolving viruses such as SARS-CoV-2 and H5N1. While the currently available mRNA vaccines are highly effective at inducing an immune response against Covid , they present challenges like the high amount of mRNA needed to produce them and the constantly evolving nature of the pathogen. "The virus changes, moving the goal post, and updating the vaccine takes some time," said senior author Suresh Kuchipudi, chair of Infectious Diseases and Microbiology at the University of Pittsburgh School of Public Health. To address these challenges, the researchers created a proof-of-concept Covid vaccine using what's known as a "trans-amplifying" mRNA platform. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Pare a neuropatia: descubra como NeuroFit Undo In this approach, the mRNA is separated into two fragments -- the antigen sequence and the replicase sequence -- the latter of which can be produced in advance, saving crucial time in the event a new vaccine must be developed urgently and produced at scale. In addition, the researchers analysed the spike-protein sequences of all known variants of the SARS-CoV-2 for commonalities, rendering what's known as a "consensus spike protein" as the basis for the vaccine's antigen. Live Events In mice, the vaccine induced a robust immune response against many strains of SARS-CoV-2. "This has the potential for more lasting immunity that would not require updating, because the vaccine has the potential to provide broad protection," said Kuchipudi. "Additionally, this format requires an mRNA dose 40 times less than conventional vaccines, so this new approach significantly reduces the overall cost of the vaccine." The study, published in the journal npj Vaccines could inform more efficient vaccine development for other constantly evolving RNA viruses with pandemic potential, Kuchipudi said.
