12% of Americans are responsible for over half of all U.S. beef consumption

Researchers have unveiled a staggering figure from a recent study. A mere 12% of Americans are responsible for over half of all beef consumption in the U.S. every day.

This finding, now published in the respected journal Nutrients, might be the key to shaping our understanding of beef consumption patterns. This knowledge can subsequently guide consumer groups and government bodies in creating educational messaging to highlight the detrimental health and environmental repercussions of beef consumption.

The 12% segment of the population, predominantly men or individuals between the ages of 50 and 65, consume what researchers have termed an “outsized” quantity of beef daily. To provide a context, the latest Dietary Guidelines for Americans recommend only 4 ounces per day of meat, poultry, and eggs combined for those consuming a daily intake of 2200 calories.

Studying beef consumption in the U.S.

The study’s methodology was meticulous and vast. Researchers from Tulane University and the University of North Carolina at Chapel Hill analyzed data extracted from the CDC’s National Health and Nutrition Examination Survey, which documented the meals of over 10,000 adults within a day.

It’s pertinent to note that our global food system is a significant contributor to greenhouse gas emissions, generating a colossal 17 billion tons annually. This figure represents approximately one-third of all greenhouse gases resulting from human activities. The beef industry, in particular, has a hefty carbon footprint. It is responsible for emissions that are 8-10 times higher than those of chicken and astonishingly, more than 50 times higher than beans.

Professor Diego Rose from Tulane University School of Public Health and Tropical Medicine, who was the senior author of the study, provided insight into the rationale behind the research. “We focused on beef due to its pronounced impact on the environment, coupled with its high saturated fat content, which is detrimental to health.”

Prof. Rose highlighted the objective of the study. He says it aimed “to assist in tailoring educational programs or awareness campaigns for those consuming excessive amounts of beef.”

Small percentage drives overall demand

As climate change increasingly dominates global discussions, with awareness and concern at an all-time high, this study’s findings become ever more relevant. What stood out for Professor Rose and his colleagues was the realization that such a significant portion of beef consumption was driven by a small percentage of the population.

While this could be seen as a positive – imagine the impact if this 12% reduced their beef intake – Rose also highlighted a concern: “On the other hand, those 12% may be most resistant to change.”

Intriguingly, the study also discovered a correlation between awareness of USDA’s MyPlate food guidance system and reduced beef consumption. Amelia Willits-Smith, lead author and a post-doctoral fellow at the University of North Carolina at Chapel Hill, suggested, “Exposure to dietary guidelines might be instrumental in altering eating habits.”

Primary sources of beef consumption

Furthermore, the study identified the primary sources of beef in a typical American diet. While almost a third originates from pure cuts like steaks or briskets, six out of the top ten sources are from mixed dishes such as burgers, burritos, and spaghetti with meat sauce. Willits-Smith pointed out a simple solution, “If you’re getting a burrito, opt for chicken instead of beef.”

A silver lining emerged in the study’s demographic findings. Those below the age of 29 and above 66 were least inclined towards excessive beef consumption.

For Rose, this indicated a potential shift in the younger generation’s priorities. “There’s hope in the younger generation because it’s their planet they’re set to inherit,” he commented. “I’ve observed their keen interest in understanding how diet impacts the environment and their role in it.”

In addition to Rose and Willits-Smith, the research team included Dr. Keelia O’Malley and Harmonii Odinga from Tulane University.

This extensive study not only sheds light on the eating habits of a significant segment of the American populace but also underscores the pressing need to address the environmental and health implications of our dietary choices.

The environmental impact of the beef industry

The beef industry stands as one of the most environmentally demanding sectors in the global food system. Its impact on our planet is multi-faceted, from deforestation to greenhouse gas emissions. Let’s delve into the significant ways the beef industry affects our environment.

Beef consumption causes deforestation

Beef production and consumption is a primary driver for deforestation, especially in the Amazon rainforest. Ranchers clear vast areas of forest to create pastures for cattle grazing.

This deforestation not only destroys biodiversity-rich habitats but also releases massive amounts of carbon dioxide, a potent greenhouse gas stored in trees.

Greenhouse gas emissions

Cattle produce methane during digestion, a process known as enteric fermentation. Methane is over 25 times more effective at trapping heat in the atmosphere than carbon dioxide over a 100-year period. The beef industry, thus, significantly contributes to global warming.

Water consumption

Raising cattle demands a lot of water. It takes roughly 1,800 gallons of water to produce just one pound of beef. This encompasses water for the cattle to drink, irrigate the crops they eat, and process the meat. In water-scarce regions, this intensive usage exacerbates local water shortages.

Land use

Beef production occupies more land than any other meat production. Large swaths of land are required for grazing and growing feed crops, often leading to habitat loss for many species.


Runoff from beef farms, laden with pesticides, fertilizers, and manure, often finds its way into rivers and oceans. This runoff can create “dead zones,” areas where the oxygen levels are too low to support most marine life, disrupting aquatic ecosystems.


Cattle can strain the land they graze on, leading to soil degradation. Overgrazing strips the soil of its vegetation, exposing it to erosion and reducing its ability to store carbon, thereby further contributing to climate change.

In summary, while beef consumption remains high as a staple in many diets worldwide, its production comes with a hefty environmental price tag. As consumers become more environmentally conscious, it’s crucial to recognize the impact of our dietary choices and consider sustainable alternatives.
