The amino acid pattern of the British diet

The amounts of the essential amino acids in the average British household food supply have been calculated and compared with those recommended by FAO/WHO. There were large excesses of all essential amino acids, with threonine being the most limiting. When similar calculations were made ten years ago, the sulphur-containing amino acids were the most limiting. The change results not so much from the greater amounts of animal protein which are now eaten as from changes in the reference pattern of amino acids.
