Adherence
Eliminating in vivo digestibility requirements (PDCAAS) for protein content claims and relying solely on protein amount per serving aligns food labeling with dietary guidelines, promotes plant-based food consumption, and improves public health outcomes.
If you are eating enough total protein from varied sources, you do not need to worry about complex protein quality scores on labels. Focus on choosing plant-based protein sources (beans, lentils, soy) which are often disadvantaged by current labeling rules. This change helps you make healthier choices that lower saturated fat and increase fiber, supporting long-term health without needing to track complex metrics.
Relying solely on the amount of protein per serving could better align with dietary guidelines, facilitate amino acid complementation, and promote human health and sustainable food production, while avoiding animal use in testing. This approach is appropriate for populations who already consume protein in excess of reference values from varied sources.
Why this rating
Based on modeling studies and roundtable consensus rather than direct long-term clinical trials of the regulatory change itself.
