Food and Health: Considerations of the Protein Metabolism with Special Reference to Amino Acid Requirements and Imbalance

  • Hugo E. Aebi


Health versus hunger is the most drastic and also the most important contrast in today’s world. It is no exaggeration to state that one of the main conditions for man’s health is the availability of a well balanced nutrition in adequate quantity. There are three reasons to focus these considerations on proteins:
  • They represent — as indicated by the name given to this class by Muldern in 1838 — the body constituent of primary importance. This is true not only quantitatively, but also qualitatively, since all enzymes, the catalysts of living matter, belong to this class.

  • As a food component they have the unique property to be a source of amino acids required for protein synthesis as well as to serve as an energy donor, both aspects being closely related.

  • World wide shortage in supply is most pronounced in this class of foods. The following discussion on the relationship between food and health focuses on the production of more, inexpensive, edible proteins, since this is the most significant area to attack in the battle against hunger.
