Claims about the health dangers of red meat are not only improbable in the light of our evolutionary history, they are far from being supported by robust scientific evidence

Should dietary guidelines recommend low red meat intake? Frédéric Leroy & Nathan Cofnas. Critical Reviews in Food Science and Nutrition, Sep 5 2019. https://doi.org/10.1080/10408398.2019.1657063 

Abstract: Mainstream dietary recommendations now commonly advise people to minimize the intake of red meat for health and environmental reasons. Most recently, a major report issued by the EAT-Lancet Commission recommended a planetary reference diet mostly based on plants and with no or very low (14 g/d) consumption of red meat. We argue that claims about the health dangers of red meat are not only improbable in the light of our evolutionary history, they are far from being supported by robust scientific evidence.

6. Conclusions

Although meat has been a central component of the diet of our lineage for millions of years, some nutrition authorities—who often have close connections to animal rights activists or other forms of ideological vegetarianism, such as Seventh-Day Adventism (Banta et al., 2018)—are promoting the view that meat causes a host of health problems and has no redeeming value. We contend that a large part of the case against meat is based on cherry-picked evidence and low-quality observational studies. The bald claim that red meat is an “unhealthy food” (Willett et al., 2019) is wildly unsupported.

Based on misrepresentations of the state of the science, some organizations are attempting to influence policy makers to take action to reduce meat consumption. Simplification of complex science increases persuasive power but may also serve ideological purposes and lead to scientistic approaches. According to Mayes and Thompson (2015), manifestations of nutritional scientism in the context of biopolitics can have various ethical implications for “individual responsibility and freedom, concerning iatrogenic harm, and for well-being”. Well-meaning yet overemphasized and premature recommendations may eventually cause more damage than benefit, not only physiologically but also by unjustifiably holding individuals accountable for their health outcomes. We believe that a large reduction in meat consumption, such as has been advocated by the EAT-Lancet Commission (Willett et al., 2019), could produce serious harm. Meat has long been, and continues to be, a primary source of high-quality nutrition. The theory that it can be replaced with legumes and supplements is mere speculation. While diets high in meat have proved successful over the long history of our species, the benefits of vegetarian diets are far from being established, and its dangers have been largely ignored by those who have endorsed it prematurely on the basis of questionable evidence.
