Vegetable protein is poor quality compared to the protein in meat however
its possible to increase the quality of vegetable protein by combining it
with other plant foods. This is a common way vegetarians obtain high quality
protein with a diet low in calories and fat. An example of combining plant
proteins would be a vegetable curry with rice or naan bread. The two foods
complement each other because vegetable protein lacks certain essential
amino acids but these are present in the rice and bread forming a meal
with a
complete protein source.
If all essential amino acids are not present vegetable protein cannot be
used for growth or maintenance of tissues. In this case the vegetable
protein is usually burned as fuel or may be converted into fat.
