The correct answer is mutual supplementation.
It is important to take the essential amino acids, and it is not essential to get them from poultry, meat, fish, and other complete-protein foods. There is a dietary method known as mutual supplementation. In this, one combines complementary partial-complete protein foods to consume enough concentrations of all the essential amino acids.
For instance, both brown rice and beans are quite abundant in protein, each one is devoid of one or more of the important amino acids. When the beans are eaten in combination with brown rice, the outcome is equal to a complete protein, which can be substituted for meat.
