What are the best dietary sources of essential amino acids for humans?

Answer 1

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; making them the reference for absorbable protein
Milk or Whey, bovine is limited in methionine (or cysteine)

You have to have a mixture of foods to make sure of getting all the essential amino acids. Beans on toast is a good example (pulses and wheat )

Answer 2

proteins form a variety of animal and plant sources as not many foods have all the amino acids you may require in the correct amounts
