What are complementary proteins?

Complementary proteins refer to the concept of combining different food sources to create a complete protein profile. This idea is particularly important for individuals following vegetarian or vegan diets, where certain plant-based proteins may lack one or more essential amino acids.

When two or more foods are paired together, they can provide all of the essential amino acids needed for the body. For example, rice lacks certain amino acids that beans provide, while beans may lack others that rice offers. By consuming these foods together—such as rice and beans or corn and peanuts—you create a more balanced intake of proteins that complement one another, thus ensuring that your body receives the full spectrum of essential amino acids.

This understanding helps individuals meet their nutritional needs and promotes a holistic approach to meal planning, particularly in plant-based diets.
