A new study from the Indiana University School of Public Health is reshaping the conversation around diet and prediabetes, suggesting that moderate beef consumption may not be as harmful as commonly believed.
With more than 135 million adults in the United States either living with or at risk of type 2 diabetes, the need for clear, science-backed dietary guidance has become increasingly urgent.
One long-standing debate has centered on whether red meat, particularly beef, worsens metabolic health in individuals already at risk.
However, findings from a recent randomized controlled trial published in Current Developments in Nutrition indicate that consuming moderate amounts of beef may not negatively impact key health markers when compared to poultry.
Inside the Study
The study followed 24 adults aged 18 to 74 who were overweight or obese and had prediabetes but were otherwise healthy.
Using a crossover design, participants alternated between two 28-day diet phases—one including beef and the other poultry—with a washout period in between.
Each participant consumed two daily meals containing either beef or poultry, totaling about 6 to 7 ounces (170–198 grams) of meat per day. Meals included common dishes such as stews, burgers, burritos, and stir-fries, while participants maintained their usual diets outside the provided meals.
Key Findings
Researchers assessed important indicators of metabolic health, including insulin sensitivity, β-cell function, and inflammation. These factors play a critical role in the development of type 2 diabetes.
The results showed no significant differences between the beef and poultry diets across all measured outcomes. In other words, eating unprocessed beef daily did not worsen blood sugar regulation, insulin response, or inflammation compared to poultry.
What It Means
The findings suggest that beef, when consumed as part of a balanced and healthy diet, does not inherently increase cardiometabolic risk in people with prediabetes.
While the study duration was relatively short, experts note that one month is generally sufficient to observe measurable metabolic changes. Still, they emphasize the importance of overall dietary patterns rather than focusing on a single food group.
The Bigger Picture
This research adds nuance to dietary recommendations, highlighting that moderation and balance remain key. Rather than eliminating specific foods entirely, individuals at risk of type 2 diabetes may benefit more from maintaining a well-rounded diet that includes a variety of nutrient sources.
