It is the duty of the housewife to furnish a well-balanced diet to the mem- 

 bers of her family. By taking something from each group of food materials 

 she will be able to supply. all of the five food substances — protein, fat, carbohy- 

 drates, minerals and water — which are necessary. The correct proportions of 

 each, however, must be determined by the individual requirements and pecu- 

 liarities. Appetite, age, sex, occupation, climate and season must all be con- 

 sidered when making a well-regulated diet for the normal person. 



This parting injunction is given in one of the United States Farmers' Bulle- 

 tins by Professor Atwater : 



"It should always be remembered that 'the ideal diet is that combination of 

 foods which, while imposing the least burden on the body, supplies it with 

 exactly sufficient material to meet its wants,' and that any disregard of such 

 a standard must inevitably prevent the best development of our powers."
