Protein quality of enteral nutritionals: a response to Young
Article Abstract:
An assessment of the protein quality of six enteral products revealed that the quality of the nutritionals were below casein in adjested relative protein efficiency ratio values and protein digestibility-correction scores. The study also indicate that the protein digestibility-corrected amino acid score (PDCAAS) method can not efficiently calculate the extra nutritional values of proteins with scores above the reference protein and fails to consider thenegative effects of antinutritional factors on the enteral nutritionals. The study also criticized the PDCAAS for failing to consider the effects of supplemental amino acids in protein quality of low digestibility and low quality proteins.

Human amino acid requirements: counterpoint to Millward and the importance of tentative revised estimates
Article Abstract:
D.J. Millward generated confusion and several arguments regarding studies on interspecies comparisons relating to amino acid requirement patterns. Millward argued that higher growth rates were observed in animals compared to humans at any of the life stages used in the studies. He failed to understand that the amino acid requirement pattern expressed for each specific unit of amino acid had a lower international value compared to estimates in nonhuman adult species. Also, he failed to recognize the existence of reliable stable isotope studies for lysine requirements.

Protein quality of enteral nutritionals
Article Abstract:
A nutrient bioassay/amino acid score investigation was conducted to determine the validity of the amino acid requirement pattern established by international health and nutrition organizations for determining the quality of dietary proteins for all ages. The study revealed that the protein quality of the six enteral products assessed were lower than methionine-supplemented casein. The study, however, failed to present evidence to support criticisms of the protein digestability-corrected amino acid score method.
