No evidence of adverse health effects from meat consumption: Study
Adults can continue to eat their current levels of red meat, as well as processed and unprocessed meats, unless they feel inclined to change their habits for non-nutritional reasons, according to a panel of reviewers who conducted several recent studies and developed a new guideline on the topic.
An editorial accompanying the studies and guideline stated, “This is sure to be controversial, but it is based on the most comprehensive review of the evidence to date. Because that review is inclusive, those who seek to dispute it will be hard pressed to find appropriate evidence with which to build an argument.”
Unprocessed red meat and processed meat are unlikely to be causal factors for adverse health outcomes, although it is possible they have a very small causal effect, the guideline stated. The guideline, editorial, and reviews were published by Annals of Internal Medicine on Oct. 1.
The guideline stated, “Our weak recommendation that people continue their current meat consumption highlights both the uncertainty associated with possible harmful effects and the very small magnitude of effect, even if the best estimates represent true causation, which we believe to be implausible.”
The guideline was developed by a panel based on four de novo systematic reviews that considered evidence on consumption of meat, as well as one review that addressed consumers' beliefs and values about consuming it. The reviews included data from millions of patients.
The first review was a meta-analysis of cohort studies that focused on how dietary patterns, including the amount of red or processed meat consumed, affected all-cause mortality, cardiometabolic outcomes, and cancer incidence and mortality. More than 100 studies including more than six million participants were analyzed. The overall conclusions were that dietary patterns, including differences in meat consumption, may result in only small differences in outcomes over long periods.
The next study was a meta-analysis that looked specifically at cohort studies examining how reductions in red and processed meat might affect cancer incidence and mortality. It included 118 studies with more than six million participants, and it, too, found that the possible impact of reduced meat intake was very small.
The third study was a meta-analysis of cohort studies that looked specifically at meat consumption and its relationship to all-cause mortality and cardiometabolic outcomes and found that any link was very small.
In the fourth analysis, researchers examined randomized controlled trials that compared diets with differing amounts of red meat for at least six months. They found 12 eligible studies, but one of them—the Women's Health Initiative—was so large (almost 49,000 women) that it dominated the analysis. The authors concluded that diets restricted in red meat may have little or no effect on major cardiometabolic outcomes and cancer mortality and incidence, although the certainty of the evidence was low.
Finally, a review of consumers' beliefs about meat consumption found that reasons for eating meat included enjoyment, the belief that meat was essential to a healthy diet, cultural reasons, and disbelief about potential negative health effects.
The editorial said that nutritional epidemiology research often has methodological problems and that it may be time to stop producing observational research in this area. “These meta-analyses include millions of participants. Further research involving much smaller cohorts has limited value,” the editorial said. “High-quality randomized controlled trials are welcome, but only if they're designed to tell us things we don't already know.”
Instead, the editorial continued, a major overhaul of the methods for communicating nutritional data is needed to reach target populations and change health outcomes. One potential takeaway from these studies is that there are many reasons other than health to reduce meat consumption, the editorialists said.
“Ethical concerns about animal welfare can be important, as can concerns about the effects of meat consumption on the environment,” they wrote. “Both of these issues might be more likely to sway people, and they have the added benefit of empirical evidence behind them. And if they result in reducing meat consumption, and some receive a small health benefit as a side effect, everyone wins.”

Congress' leniency led to Waqf boards flouting norms, claims Kangana Ranaut
Shimla, Apr 5 (PTI): The Congress' leniency towards Waqf boards led to them flouting norms, BJP MP Kangana Ranaut alleged on Saturday and said the Waqf (Amendment) Bill passed by Parliament would address the issue of largescale land-grabbing.
Addressing a Jan Sampark Abhiyan in the Majhvad area of her Mandi constituency, the actor-politician welcomed the Waqf bill's passage and claimed there was a big conspiracy behind the formation of Waqf boards even before Independence.
The entire country is suffering till now because of that, she alleged.
The new legislation will address the issue of significant encroachments, she claimed and alleged huge chunks of land had been grabbed in the name of Waqf boards.
Parliament approved the Waqf (Amendment) Bill, 2025, early on Friday after the Rajya Sabha gave its nod to the contentious legislation following an over 13-hour debate.
The Bill was passed in the Rajya Sabha with 128 members voting in favour and 95 opposing it. It was passed in the Lok Sabha early on Thursday, with 288 members supporting it and 232 against it.
Ranaut also said Congress leaders elected from Mandi did not raise their voices for the people in Parliament.
That is why Himachal Pradesh is in huge debt today, she claimed.
The BJP MP, who hails from Mandi, said Congress leaders made an uncalled-for remark about the district -- also known as Chhoti Kashi -- to defame it while she was preparing to return home.
Ranaut was referring to a comment by Congress spokesperson Supriya Shrinate after the actor-politician was fielded by the BJP in the 2024 Lok Sabha polls that had evoked strong reactions.
Speaking in the local dialect, she expressed her gratitude to the people of Mandi for electing her and said she would work for their welfare as a sister and daughter.
Earlier, Ranaut paid obeisance at the Bhoot Nath temple.
