 work and for women and children, according 10 the following r.gurcs'.

H01C much protein to use. — A perplexing problem is tiiat which con- 

 cerns itself with what proportion of the food shall be protein and' fat 

 and carbohydrate. There is considerable di.Terence of opinion at this 

 point, for some of those persons who are recognized as authorities believe 

 that the amount of protein in the diet should be low, while others, whose 

 knowledge is equally as great, take the opposite view. A few of the 

 arguments used by those in favor of the low protein diet are that tliC 

 protein eaten in excess of body needs is immediately gotten rid of instead 

 of being possibly stored, as is the case with fats and carbohydrates ; 

 that this throws a strain on the kidneys; that the waste products of 

 protein may accumulate in the tissues when large amounts of this food- 

 stuff are consumed and may cause general irritation of all the tissues. 

 Those favoring the other side argue that in the history of nations we 

 find the strongest peoples are those who have had a liberal protein 

 diet, and that a high protein diet makes the body less susceptible to 

 disease.
