Effect of low-protein diet and its duration on hair composition.
The effect of feeding a low-protein diet (1%) and its duration (4, 8, 12 and 16 weeks) on the protein content and amino-acid pattern of hair were studied. These changes were compared with control groups fed an adequate protein diet (16%). Protein content of hair was diminished in the protein-deficient rats after four weeks followed by a gradual decrease till the end of the experiment. Sulphur-containing amino acids, cystine and cysteine, were significantly reduced in the hair of the protein-deficient rats when compared with the normal controls. The amino-acid pattern showed significant differences from controls by the end of the whole experimental period.
