Question

It is beneficial to consume foods with complete proteins because these are foods that provide many essential amino acids necessary for the body to function efficiently. Which of the following foods could be included in your diet, as a complete protein?

Answer 1

What are your options?

Answer 2

Nearly all foods contain all twenty amino acids in some quantity, and nearly all of them contain the essential amino acids in sufficient quantity. Proportions vary, however, and some foods are deficient in one or more of the essential amino acids. Though some vegetable sources of protein contain sufficient values of all essential amino acids, many are lower in one or more essential amino acids than animal sources, especially lysine, and to a lesser extent methionine and threonine. However, as shown in the example of potatoes, above, nearly all foods provide sufficient amino acids to satisfy human requirements.
