Are complete proteins found in animal foods or plant foods?

Complete proteins are primarily found in animal foods, such as meat, fish, poultry, eggs, and dairy products. These foods contain all nine essential amino acids that the human body cannot produce on its own and must obtain from food.

On the other hand, plant foods generally contain incomplete proteins, meaning they lack one or more of the essential amino acids. However, by combining different plant foods, it is possible to create a complete protein profile. For example, eating beans and rice together provides all the essential amino acids that the body needs.

Some plant foods that are relatively high in protein include legumes (beans, lentils, chickpeas), nuts (almonds, walnuts, chia seeds), and whole grains (quinoa, buckwheat, amaranth). By incorporating these foods into a balanced diet, vegetarians and vegans can obtain the necessary amounts of complete proteins.
