What are complementary foods?

  1. Foods rich in antioxidants

  2. Combinations of two incomplete proteins that make a complete protein

  3. Vegetables and fruits that enhance digestion

  4. Foods that are low in calories and high in nutrients

The correct answer is: Combinations of two incomplete proteins that make a complete protein

Complementary foods refer to combinations of two or more incomplete proteins that together provide all the essential amino acids needed to form a complete protein. This concept is particularly important for individuals who follow a vegetarian or plant-based diet, where certain plant proteins lack one or more essential amino acids. For example, beans are an incomplete protein because they are low in methionine, while rice is low in lysine. When consumed together, such as in a bean and rice dish, they complement each other and form a complete protein, thereby supplying the necessary amino acids the body requires for various functions, including muscle synthesis and overall health. Understanding the concept of complementary proteins is crucial since it highlights the importance of food combinations in achieving balanced nutrition, particularly in diets lacking animal-based protein sources. This knowledge can guide dietary choices to ensure adequate protein intake.
