What term describes protein foods containing essential amino acids?

The correct answer, which describes protein foods containing all of the essential amino acids, is "Complete Proteins." Complete proteins are those that provide all nine essential amino acids that the body cannot produce on its own. These proteins are typically found in animal products such as meat, dairy, and eggs, as well as in some plant sources like quinoa and soy.

High Biological Value (HBV) refers to proteins that are efficiently used by the body, as they have a good balance of essential amino acids. While often related to complete proteins, it is not the term that specifically describes the presence of all essential amino acids.

Low Biological Value (LBV) proteins lack one or more of the essential amino acids and are typically found in many plant sources. Incomplete proteins are another term for protein sources that do not contain all essential amino acids, which further underscores the distinction from complete proteins.

Understanding these terms is crucial in nutrition and food preparation, as it helps individuals choose appropriate protein sources to meet their dietary needs.
