Many sources claim that certain plant proteins need to be combined very specifically at every meal in order for the human body to utilize them as well as animal proteins. This theory is not exactly true.
These sources of protein are discussed in relation to their amino acid content, human amino acid requirements, and dietary protein quality.
Mixtures of plant proteins can serve as a complete and well-balanced source of amino acids for meeting human physiological requirements. This short review ends with a list of a series of myths and realities concerning the relationship between plant protein and human nutrition and a list of some nutritional issues of concern to the health professional and informed consumer.

E-mail: g-wu tamu. A protein consists of amino acids AA linked by peptide bonds. Dietary protein is hydrolyzed by proteases and peptidases to generate AA, dipeptides, and tripeptides in the lumen of the gastrointestinal tract. These digestion products are utilized by bacteria in the small intestine or absorbed into enterocytes. AA that are not degraded by the small intestine enter the portal vein for protein synthesis in skeletal muscle and other tissues. AA are also used for cell-specific production of low-molecular-weight metabolites with enormous physiological importance.
Corn germ with pericarp in relation to whole corn: nutrient contents, food and protein efficiency, and protein digestibility-corrected amino acid score. The germ fraction with pericarp bran is generated in the industrial processing of corn kernel, and it is used for oil extraction and animal feed. This study evaluated the nutritional and protein quality of this fraction in relation to whole corn. The proximate composition, mineral contents, and amino acid profile of the germ fraction with pericarp and of whole corn were determined. The germ showed higher contents of proteins, lipids, dietary fiber The corn germ fraction with pericarp is rich in dietary fiber, and it is a source of good quality protein as well as of iron and zinc, and its use as nutritive raw material is indicated in food products for human consumption.
Plant Proteins from European Crops pp Cite as. Plant proteins can differ from animal proteins in terms of digestibility, amino acid composition, the presence of antinutritional factors which influence digestibility and safety, and the presence of phytoprotectant factors which mediate disease protection. Nevertheless, plant proteins can provide all of human amino acid needs at all ages. Unable to display preview. Download preview PDF.

Indispensible amino acids IAAs are used by the body in different proportions. Most animal-based foods provide these IAAs in roughly the needed proportions, but many plant-based foods provide different proportions of IAAs. To explore how these plant-based foods can be better used in human nutrition, we have created the computational tool vProtein to identify optimal food complements to satisfy human protein needs. The quantity of food in a pair is found using a linear programming approach that minimizes total calories, total excess IAAs, or the total weight of the combination. For single foods, vProtein identifies foods with particularly balanced IAA patterns such as wheat germ, quinoa, and cauliflower. Although less useful alone, some unbalanced foods provide unusually good complements, such as Brazil nuts to legumes. These analyses suggest that pairings of plant-based foods should be based on the individual foods themselves instead of based on broader food group-food group pairings.
