The protein was the first to be considered essential nutrient required for growth and maintenance of the organism.

When we look at the proteins through a microscope, we see that they are made up of smaller particles called amino acids. Some amino acids are produced by the body and therefore are called non-essential, but there are other essential calls that need to be taken because they are not synthesized.
animal proteins such as meat, poultry, fish, milk, cheese, eggs are considered to be of good quality (or "high biological value"), because they are the best sources of these essential amino acids (those that are not produced by the body).
"Beans are low in an amino acid called methionine and rich in lysine, and the rice is low in lysine and high in methionine. Consumed together they complement each other and serve the needs of the essential amino acids."
Since the plant foods (grains, vegetables) are considered low quality (or "low biological value") for compounds are generally 10 to 30% protein and also do not have all amino acids that are essential. Despite this deficiency, the plant proteins contribute significantly to total protein intake, mainly because they have a lower financial cost.
Despite the nutritional limitations of plant proteins, the diet is balanced and varied, they will be consumed various foods that together provide a "complementary effect" of these amino acids, improving and increasing the protein value of the meal at the same level of animal protein.
A good example of this complementation is our classic beans (legumes) with rice (cereal). Beans are low in an amino acid called methionine and rich in lysine, and the rice is low in lysine and high in methionine. Consumed together they complement each other and serve the needs of the essential amino acids.
Practitioners and restrictive vegetarian diets (or vegans - exclude from the diet all foods of animal origin and derivatives) need to be aware about the deficiency of vitamin B12 is only found in meat, requiring the intake of supplements.
