The Journal of Nutrition published a new Perspective review on protein recommendations in the 2025-2030 Dietary Guidelines for Americans, examining the shift to 1.2 to 1.6 grams per kilogram of body weight daily and identifying gaps in the underlying research base, according to the American Society for Nutrition.
Evaluating Protein Benchmarks in the 2025-2030 Dietary Guidelines
The updated guidelines establish a daily protein intake range between 1.2 and 1.6 grams per kilogram of body weight. Authored by researchers at the Pennington Biomedical Research Center, the paper in The Journal of Nutrition compares this current benchmark directly against previous editions of the Dietary Guidelines.
According to the American Society for Nutrition, the review also evaluates the 2025 Dietary Guidelines Advisory Committee Scientific Report alongside contemporary clinical data. The review highlights the focus on healthy, nutrient-dense eating patterns as a primary strength of the updated federal guidance.
Evidence Gaps in Universal Protein Targets
Researchers questioned whether existing data justify a universal higher-protein target for every American across their lifespan. Dr. Stefan Pasiakos, a professor at the Pennington Biomedical Research Center who spoke on behalf of his co-authors, noted that the guidelines fall short of that standard.
“What is optimal for one segment of the population should not be considered optimal for all without sufficient evidence,” Dr. Pasiakos stated, according to the American Society for Nutrition. The authors pointed out that while higher protein intakes spanning 1.2 to 1.6 grams per kilogram effectively support weight management in individuals with overweight and obesity, the underlying evidence base lacks broad representation across all demographic groups in the U.S. population.
Future Directions at NUTRITION 2026
Discussions regarding protein metabolism, healthy aging, and dietary guidance will continue at NUTRITION 2026, the flagship annual meeting of the American Society for Nutrition. The event is scheduled for July 25-28, 2026, in National Harbor, Maryland.
Thousands of researchers and health professionals will examine these issues during featured sessions, including a plenary titled “Dietary Guidance at a Crossroads: Science, Practice, and Innovation” and a featured session on “Protein: Bridging Requirements and Food-Based Guidance,” according to the American Society for Nutrition. Additional programming will focus on muscle health and chronic disease prevention.
