Which of the following is considered a complete protein?

• A. Wheat
• B. Soy beans
• C. Lentils
• D. Potatoes

Answer: (B)

Soybeans are considered a complete protein because they contain all nine essential amino acids that the human body cannot synthesize on its own. Essential amino acids are crucial for various bodily functions, including muscle repair, immune function, and hormone production. Most plant-based protein sources, such as wheat, lentils, and potatoes, typically lack one or more of these essential amino acids, making them incomplete proteins when taken alone. In contrast, soybeans offer a balanced amino acid profile akin to that of animal proteins, which is why they are highly regarded in vegetarian and vegan diets. This characteristic makes soybeans an excellent choice for individuals looking to ensure they receive adequate protein while following a plant-based diet.
