The diet in the "secondary" anaemias requires but brief consideration. It is essential to recognize the wide range of conditions which may produce anaemia. General and local infections, intoxications of divers kinds, starvation relative or absolute, overwork mental or physical, worry, insanitary surroundings and defective personal hygiene, may be the active agents, and recovery in any case is not likely to occur until the particular cause no longer operates. When this is fulfilled, the results of treatment are usually satisfactory.

A full mixed diet is rarely if ever permissible unless the tongue is clean, the stools normal, and digestion easy and active. The dietary should be prescribed on the lines laid down in the section on Chlorosis.

The secondary anaemias of infancy and childhood may of course result from causes of the same kind and variety as those active in adult life; but dietetic errors and gastro-intestinal disturbances play on the whole a more important part than is the case in adult life. The growing child shows the effects of relative starvation very rapidly, and the slighter faults produce a more serious result. The dietary should thus in every case be carefully revised and any defects rectified; while gastro-intestinal symptoms must be treated on the lines required.
