Metabolic Evaluation of the Dietary Guidelines’ Ounce Equivalents of Protein Food Sources in Young Adults: A Randomized Controlled Trial
Is egg protein and peanut protein really equivalent?
- Consumption of ounce equivalents of animal-based protein resulted in a greater anabolic response than the ounce equivalents of plant-based protein food sources
- The improvement in whole-body net protein balance was due to an increase in protein synthesis with all the animal protein sources
- The magnitude of the anabolic response was correlated with the EAA content of the protein food source.
- The “ounce equivalents” of protein food sources as expressed in the DGAs are not metabolically equivalent in young healthy individuals
As a shift from animal to a more plant-based diet is encouraged in calls for a more environmentally sustainable global food system, guidance on how to achieve adequate protein and amino acid nutrition on a plant-based diet will become even more important. Park et al. makes an important and timely contribution which should inform expert decisions in the setting of future Dietary Guidelines for Americans.
