What are essential amino acids?

Essential amino acids are those that the human body cannot synthesize on its own and therefore must be obtained through dietary sources. This is crucial because these amino acids play a vital role in various bodily functions, including building proteins, supporting immune function, and aiding in the production of hormones and enzymes.

Without an adequate intake of essential amino acids from food, the body may not be able to maintain proper physiological processes, which can lead to health issues. Foods that typically contain essential amino acids include meat, fish, eggs, dairy products, and certain plant-based sources such as quinoa and soy, making it important for individuals following diets with limited animal products to be particularly mindful of their amino acid intake.
