Daily Beef Consumption May Not Increase Prediabetes Risk, New Study Finds

A new randomized controlled trial suggests that consuming beef daily may not increase the risk factors associated with type 2 diabetes for individuals living with prediabetes. The findings indicate that eating 6 to 7 ounces of beef per day does not negatively impact blood sugar regulation, insulin function, or inflammation when compared to diets centered on poultry.

The research, which was published in the journal Current Developments in Nutrition, provides new evidence regarding dietary patterns for a significant portion of the population. According to the study, the daily consumption of beef over a one-month period showed no adverse effects on key cardiometabolic health markers in adults with prediabetes.

This study addresses an urgent public health concern, as more than 135 million American adults are currently living with or are at risk for type 2 diabetes. As this population grows, the need for evidence-based dietary guidance to manage risks and complications becomes increasingly critical.

Study Design and Methodology

The researchers utilized a randomized, crossover trial design to compare the effects of beef and poultry on various health indicators. In this type of study, participants undergo different dietary interventions during separate periods, allowing for a direct comparison of how different foods affect the same individual.

The trial included 24 adults, consisting of 17 males and 7 females, with ages ranging from 18 to 74 years. All participants in the study were characterized as being overweight or having obesity and were diagnosed with prediabetes.

To ensure the accuracy of the results, the study implemented a structured timeline. Participants completed two distinct 28-day dietary intervention periods. These two periods were separated by a 28-day washout period, a method used to prevent the effects of the first dietary phase from influencing the results of the second.

Cardiometabolic Health Markers

The study specifically examined how different protein sources influenced several critical health metrics. The researchers focused on:

• Pancreatic $beta$-cell function
• Blood sugar regulation
• Inflammation levels
• Other cardiometabolic health indicators

The findings demonstrated that the consumption of 6 to 7 ounces of beef daily did not result in a worsening of these markers when compared to the poultry-based diet group. This suggests that beef, when integrated into a healthy dietary pattern, does not appear to adversely affect the cardiometabolic risk profile of those with prediabetes.

Expert Perspectives

Kevin C Maki, PhD, an adjunct professor in the Indiana University School of Public Health-Bloomington and the senior author of the study, noted that the results support existing scientific evidence regarding beef and heart health.

Results from this gold standard RCT build on existing scientific evidence that shows eating beef as part of a healthy dietary pattern supports heart health and does not adversely impact measures of blood sugar regulation or inflammation,

Dr. Maki further explained that when beef is consumed as part of a healthy dietary pattern, it can help fill essential nutritional gaps without negatively impacting cardiometabolic risk markers compared to poultry consumption.
