Nntritive Value of Meats, — In a recent 

 article on the value of meats as food, in the 

 Dietetic and Hygienic Gazette, Prof. R. H. 

 Chittenden corrects several very widespread 

 misconceptions regarding meat values. He 

 says : " The cheapest food is that which sup- 

 plies the most nutriment for the least money. 

 The well-known maxim that ' the best is the 

 cheapest ' is not true of foods, for the term 

 best iu this connection is ordinarily applied to 

 that which has the finest appearance, the finest 

 flavor, the most tender structure, etc. Thus, 

 there is no more nutriment in a poimd of pro- 

 teid from tenderloin steak than in the same 

 weight of proteid from the neck or shoulder, 

 and yet note the great difference in cost. The 

 tenderloin will not supply the body's needs one 

 particle better than the coarse-grained meat 

 from some other quarter. A great deal of 

 money is spent by people who can ill afford 

 it, because of this notion that the more ex- 

 pensive cuts are the more nutritious ; much 

 of it is perhaps attributable to lack of knowl- 

 edge of the art of cookery. The housewife, 

 not knowing how to properly prepare the 

 cheaper grades of meat so as to make them 

 palatable and attractive, concludes that they 

 are not as nutritious as the more tender and 



juicy cuts that can be bought only at a 

 higher price, and which require little judg- 

 ment or skill to prepare for the table. Here 

 is a field for missionary labor that will well 

 repay the cultivation. Knowledge of this 

 kind may be advantageously acquired by 

 those whose means render it perhaps less 

 vital ; for a waste of food material is a crime 

 against both pocket and morals." In speak- 

 ing of the value of meat as a food in relation 

 to the other food stuffs. Prof. Chittenden 

 says : " Various extractives, active principles, 

 etc., all endowed with more or less physi- 

 ological properties, are likewise ingested as a 

 part of the meat, and add their effects, per- 

 haps to aid in keeping up the tone and vital- 

 ity of the organism. Meats have certain 

 stimulating properties, which distinguish 

 them from the grosser vegetable foods. In 

 this respect they might perhaps almost be 

 classed with such articles as tea, coffee, etc., 

 in their power of ministering to the wants of 

 the brain and nerves. As Sir William Roberts 

 well says : ' The struggle for existence, or 

 rather for a higher and better existence, 

 among civilized men is almost exclusively a 

 brain struggle, and these brain foods must 

 be regarded as a very important part of the
