Which food is a complete protein?

• A. Lentils
• B. Rice
• C. Eggs
• D. Peanuts

Answer: (C)

A complete protein provides all nine essential amino acids in sufficient amounts for the body's needs and is typically highly digestible. Eggs fit this criterion because they deliver a full, well-balanced amino acid profile that the body can use efficiently. The other options are plant-based and are generally incomplete proteins, meaning they don't supply one or more essential amino acids in adequate amounts when eaten alone. Lentils are low in methionine, rice is low in lysine, and peanuts are limited in one or more essential amino acids as well. You can still get complete protein from plants by combining foods, but eggs deliver the complete set on their own.
