essential amino acids
Must-eat protein components
Essential amino acids are the subset of amino acids that the human body cannot synthesize and must obtain from food.
There are nine: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Animal proteins typically contain all nine; plant proteins often lack one or more, requiring varied sources for complete nutrition.
