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.”

Three company directors held in Rs 100-crore investment fraud in Kochi
Kochi (Kerala) (PTI): Police on Sunday arrested three directors of a firm accused of cheating hundreds of investors of over Rs 100 crore through a fake investment scheme linked to agricultural tourism here, officials said.
The accused were identified as Muraleedharan, Ashik Murali and Akhil Murali, all natives of Thrissur.
The arrests were made by the Kalamassery police in connection with a fraud involving ATCOS (Agri Tourism Cooperative Society), a firm headquartered at Pathadipalam here.
Police said the company had promised high returns by collecting investments from the public in the agricultural tourism sector, but allegedly cheated hundreds of people and fled with the money.
ATCOS was registered under the Multi-State Cooperative Societies Act and operated 13 branches across various districts in Kerala, besides a branch in Coimbatore in Tamil Nadu, officials said.
When investors failed to receive their promised returns or the invested amount, complaints were filed with the police.
Officials said around 54 cases have been registered against the firm in 32 police stations across the state, including 29 cases at the Kalamassery police station alone.
Following instructions from Kochi City Police Commissioner K S Mahesh Kumar, a special investigation team was formed under the supervision of Deputy Commissioner of Police (Law and Order) Shehensha and Thrikkakara ACP Manoj Kumar.
The team traced the accused to an apartment in Amala Nagar in Thrissur, where they had been hiding after secretly renting the flat, officials said.
The bank accounts of the accused have been frozen, and steps have been initiated to trace their assets, officials said.
Police also conducted a raid at the company’s office at Pathadipalam and seized several documents related to the case.
The accused were produced before the Judicial First Class Magistrate Court in Kalamassery, which remanded them to judicial custody and sent them to Kakkanad jail.
Police said they would seek the custody of the accused for further interrogation as the investigation continues.
