What is an example of a complete protein found in plant-based sources?

• A. Quinoa
• B. Rice
• C. Peanuts
• D. Almonds

Answer: (A)

A complete protein is one that contains all nine essential amino acids that the body cannot synthesize on its own. Quinoa is considered a complete protein among plant-based foods because it provides all these essential amino acids in adequate amounts, making it a valuable source of protein especially for those following vegetarian or vegan diets. While rice, peanuts, and almonds do provide protein, they do not contain all nine essential amino acids in sufficient quantities to be classified as complete proteins. For instance, rice lacks lysine, and while peanuts and almonds have protein, they also lack certain essential amino acids when compared to quinoa. Therefore, quinoa stands out as a complete protein option, making it essential for individuals seeking a well-rounded plant-based protein source.
