Which category best describes proteins that include all essential amino acids?

Proteins that contain all essential amino acids are categorized as complete proteins. Essential amino acids are those that the body cannot synthesize on its own and must be obtained through the diet. Complete proteins provide a full spectrum of these amino acids, making them crucial for various bodily functions, including tissue repair, muscle development, and the production of hormones and enzymes. Common sources of complete proteins include animal products like meat, fish, eggs, and dairy, as well as certain plant-based options like quinoa and soy.

Other protein categories, such as partial or deficient proteins, do not provide all essential amino acids, which can lead to nutritional imbalances if they are the primary source of protein in the diet. Therefore, identifying proteins as complete, in this context, highlights their comprehensive nutrient profile and their importance in overall health.
