Recent Beef Checkoff-funded research adds to a growing body of evidence reinforcing the important role fresh beef plays in a healthy, sustainable diet. Animal-sourced foods, such as red meat, are often assumed to be associated with obesity risk. However, Texas Tech University researchers conducted a comprehensive analysis of available research on the relationship between unprocessed red meat intake and obesity, finding no significant effect of such intake on weight gain or related metabolic issues in adults.
“Beef contains high-quality protein and other essential nutrients, and people enjoy this key source of nourishment – yet they’re often discouraged to consume red meat based on recommendations primarily driven by observational evidence,” noted the lead researcher, Nikhil V. Dhurandhar, PhD, chair of the Department of Nutritional Sciences and associate dean for innovation for the College of Health & Human Sciences. “Our study is the first to fully review the totality of causative evidence, which shows no protective or adverse effect of unprocessed red meat intake on obesity.”
Dhurandhar explains that previous related studies are based primarily on observational data, which often rely on self-reported dietary and lifestyle information that can be inaccurate and confound study results and conclusions. Instead, the researchers used rigorous research methods by conducting a systematic review and meta-analysis of 19 human clinical trials. They focused solely on studies that determined the effect of direct feeding of unprocessed red meat to participants rather than studies that used self-reported data. The result is the most comprehensive evaluation of red meat intake and obesity to date, according to Dhurandhar.
“Protein-rich foods, such as beef, may improve satiety and fullness, which can help support lifestyle and dietary behaviors that promote weight loss and healthy weight maintenance,” Dhurandhar added. “However, the stigma surrounding unprocessed red meat’s role in obesity may keep many from consuming red meat, thus missing out on key benefits which may be important for weight loss and management. This study offers a complete view of the research, so clinicians and consumers can make informed decisions about the role of unprocessed beef in healthy lifestyles.”
