Essential Amino Acids are the Amino Acids that cannot be made in the body therefore we can only get them from food. These Amino Acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. In addition, the amino acids arginine, cysteine, glycine and tyrosine are considered conditionally essential, meaning they are not normally required in the diet, but must be supplied exogenously to specific populations that do not synthesize it in adequate amounts. All essential amino acids may be obtained from plant sources, and even strict vegetarian diets can provide all dietary requirements, though careful monitoring of nutrient levels is important, as limiting factors become significant when no meat is present in the diet. Wheat is limited in lysine Rice is limited in lysine Maize is limited in lysine and tryptophan Pulses is limited in methionine (or cysteine) Beef is limited in phenylalanine (or tyrosine) Egg, chicken are limited in none; mak
