May, 1929] FOODS IN A COLLEGE COMMUNITY 



29 



With the sherbets the energy content per gram of air-dry matter 

 is low, averaging 3.6 calories. The total caloric content per half pint 

 is also low, nearer 330 calories than 500 calories, as found with the 

 ice creams. The protein content is likewise lower than that of the 

 ice creams. 



The average energy content of ice cream per ten cents (purchased 

 by the half pint) is 330 calories, that of sherbets 220 calories. Econo- 

 mically, therefore, ice cream has about the same food value as many 

 of the servings of pie and some of the package sandwiches and has 

 a higher food value than the salads and sandwiches but not so high 

 as that of bread and doughnuts. 



For practical purposes, since ice cream is such a universal dessert 

 or extra indulgence, we have computed the caloric content per gram 

 of fresh weight. These results are immediately applicable to the 

 fresh weight of the ice cream eaten, and the total energy value of a 

 serving of ice cream or sherbet may thus be easily estimated with a 

 fair degree of accuracy. 



On three different days one 5-cent and one 10-cent ice cream 

 cone were purchased at the college creamery (manufacturer A). The 

 ice cream and the cones were weighed separately, and the food values 

 of the ice cream alone and of the cone alone were calculated, based 

 upon the analyses of ice creams from manufacturer A given in Table 



Table 11. Ice Cream Cones. 



* Average weight of cone without ice cream, 6 gm. ; energy value 4.0 cal. per 

 gram; protein content 16.6 per cent. (Rose, M. S., Laboratory handbook for diete- 

 tics. New York, 3d ed.. 1929, p. 172). 



7 Average values for 19 half-pint portions of ice cream, all flavors, purchased 

 for 15 cents of manufacturer A (see Table 10).
