The Protein Committee advances science to support future dietary protein recommendations, taking into consideration intake amounts and quality - as demand is undergoing a shift in the balance of animal, plant and novel protein sources.

Why is this research valuable?

The committee is currently sponsoring research on long-term effects of protein at levels above DRIs in a long-term cohort on cardiometabolic health, inflammation, and performance/disability.

 

Research Focus Areas

  • Anticipate potential future gaps and opportunities as the food supply shifts in terms of protein food sources and amounts.
  • Advance scientific basis of protein recommendations for broad populations based on levels and quality as they relate to acute and long-term health outcomes.

Associations between Essential Amino Acid Intake and Functional Health Outcomes in Older Adults: Analysis of the National Health and Nutrition Examination Survey, 2001–2018

Current Developments in Nutrition, 2024

The relationships between habitual essential amino acid intake and body composition, muscle strength, and physical function in older US adults are not well defined. This cross-sectional study evaluated associations between usual amino acid intakes and body composition, muscle strength, and physical function in US adults at 65 years.

In vitro Protein Digestibility to Replace in vivo Digestibility for Purposes of Nutrient Content Claim Substantiation in North America’s Context

Frontiers in Nutrition, 2024

The reliance by North American regulatory authorities on in vivo rodent bioassays to measure the protein quality for protein content claim substantiation represents a major barrier for innovation in the development and marketing of protein foods.

Amino Acid Intake and Conformance With the Dietary Reference Intakes in the United States: Analysis of the National Health and Nutrition Examination Survey, 2001–2018

Journal of Nutrition, 2023

Essential amino acid intakes in the US population exceed recommended minimum population requirements. Future studies can use the method described in this article to quantify amino acid intake and examine potential relationships with health and disease.

Protein Intake and Human Health: Implications of Units of Protein Intake

Advances in Nutrition, 2020

A literature review revealed the use of myriad units of protein intake, with differential results on cardiometabolic outcomes in nutrition research. This paper recommends that authors be specific about the use of WHO (g/kg ideal BW) compared with US (g/kg actual BW) units, and ideally use gram or percent energy in observational studies.
