Which two foods are often consumed together as complementary proteins?

Complementary proteins refer to the combination of two or more plant-based protein sources that together provide a complete amino acid profile. This is particularly important for individuals who may not consume animal proteins, which naturally contain all essential amino acids.

Rice and beans are a classic example of complementary proteins. While rice is low in certain essential amino acids, particularly lysine, beans are rich in lysine but low in methionine. When consumed together, they create a complete protein profile, thus providing all the essential amino acids needed for optimal health.

Peanut butter and bread can also be considered complementary to some extent, as whole grain bread can provide lysine, and peanut butter contributes additional amino acids. However, the rice and beans combination is more widely recognized and researched in terms of dining traditions and nutritional value.

Corn and beans are frequently paired as well, providing another example of complementary proteins. Corn is low in lysine, while beans are a good source of this amino acid, making them a complementary duo as well.

Chicken and rice do provide protein and amino acids, but since chicken is an animal product, it contains all essential amino acids and doesn't need rice to achieve a complete protein profile. Thus, while this dish is nutritious, it doesn't exemplify the
