Amino Acid Concentration Data for the U.S. - Now Available in Creme Food

This amino acid data is in addition to the standard nutrients from the Food and Nutrient Database for Dietary Studies (FNDDS). The data has been derived from the USDA National Nutrient Database for Standard Reference Release 24 and has been linked at food code level with all of the NHANES datasets available in Creme Food® (pdf).

Amino acids can be classified as one of three groups: 

  • essential amino acids,
  • conditionally indispensable amino acids and
  • non-essential amino acids.

Essential amino acids are not produced in the body and therefore have to be obtained by consuming foods such as chicken, beef, poultry and fish. Alternatively, non-essential amino acids are found within the body and therefore no extra consumption is required. Finally conditionally indispensable amino acids are amino acids that are produced in the body but in insufficient amounts and therefore have to be consumed in the diet from sources such as meat, dairy and soy.

Concentration data for the following amino acids is available in Creme Food®:


  • Histidine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Tryptophan
  • Valine
  • Isoleucine
  • Threonine


  • Alanine
  • Glycine
  • Serine
  • Hydroxyproline
  • Aspartic acid

Conditionally Indispensable

  • Cystine
  • Glutamic acid
  • Proline
  • Tyrosine
  • Arginine

Intakes of any of the above amino acids cane now be easily assessed for different demographic groups across the U.S. This data is installed in our clients account on request, so please contact us if you wish to have this data added to your Creme Food® account.
