Quizplus · Accepted Answer

Unless complemented by other sources,legumes,nuts,and grains are likely to contribute to protein deficiency because they are low-quality proteins.This category has at least one essential amino acid that is insufficient for optimal protein synthesis.If fed as the only protein source,low-quality proteins will support life,but normal growth cannot be supported.By contrast,high-quality proteins are well balanced in their essential amino acid content.
