Since fats are essential for growth and nutrition as well as force production, fatty food is indicated for convalescence from severe acute diseases, and for patients suffering from chronic wasting diseases, in both of which classes there has been considerable waste of the tissues. Persons whose general health has been impaired by bad hygienic surroundings, children who have been wrongly fed by ignorant or poor parents who could not obtain proper food for them, and aged persons in whom the nutritive processes are becoming less and less vigorous, may all be benefited by supplying a sufficient amount of fatty food in the dietary.

For scrofulous and tuberculous patients fats are especially indicated. There is therefore a very large variety of diatheses and diseases, both local and general, which may be benefited by improving the nutrition of the body and increasing force production through the agency of easily digestible forms of fatty foods.
