PEARL— STAPLE COMMODITIES AND 



modity groups on which the most stress was laid in the conservation 

 campaign show a reduction in the part which they play in national 

 nutrition. The effect of the conservation work will, however, be 

 more clearly shown when we come to the consideration of individual 

 commodities. 



Of the fat normally consumed 51 per cent, is furnished by the 

 meats as a group ; 27 per cent, by the dairy products ; and 12 per 

 cent, by the vegetable oils and nuts. The grains normally furnish 

 3.98 per cent, of the fat intake and in 1917-18 this rose slightly to 

 4.16, due to the increased consumption of corn meal. 



The sugars stand second in the list as contributors of carbohy- 

 drate to consumption, with 26 per cent, of the total, to which 56 per 

 cent, is furnished by the grains. Of the remainder of the carbo- 

 hydrate intake vegetables normally contribute about 9 per cent., the 

 dairy products 5 per cent., and the fruit 4 per cent. 



The energy values of the groups are especially interesting as 

 furnishing a general index of food values. Of the total energy fur- 

 nished by the human food consumed 35 per cent, comes from the 

 grains, 22 per cent, from the meats, 15 per cent, from the dairy 

 products and 13 per cent, from the sugars. These four groups 

 make up about 85 per cent, of the total energy value of all the food
