INGESTION OF CARBOHYDRATES. 



191 



quotients were very irregular, but no extraordinarily high values were 

 obtained. No pronounced effect upon either the gaseous metabolism 

 or the heat production as a result of the ingestion of bananas is 

 apparent in this experiment. 



TABLE 117. F. M. M., February 8, 1910. Sitting. (1-hour periods.) 



Bananas: 



Amount, 400 grams; nitrogen, 0.83 gram; total energy, 413 cals. 



Fuel value: Total, 406 cals.; from protein, 5 p. ct.; from fat, 6 p. ct.; from carbohydrates, 



89 p. ct. 



Nitrogen in urine, 0.46 gram per hour. 



Basal values (February 8, 1910): CO 2 , 25.5 grams; Oa, 22.5 grams; heat, 1 82 cals.; respiratory 

 quotient, 0.83. Nitrogen in urine, 0.45 gram per hour. 



eliminated corrected for change in body-weight, but not for change in body-temperature. 

 2 Subject finished eating 17 minutes after the beginning of this period. The eating occupied 

 10 minutes. 



Dr. H., February 14, 1910 (403 grams bananas, with a fuel value 

 of 409 calories). According to the data given in table 118, noticeable 

 increases in the carbon-dioxide production, oxygen consumption, and 

 computed heat production were found. The respiratory quotients 

 were all above 0.90. 



TABLE 118. Dr. H., February 14, 1910. Sitting. (1-hour periods.) 



Bananas: 



Amount, 403 grams; nitrogen, 0.83 gram; total energy, 416 cals. 



Fuel value: Total, 409 cals.; from protein, 5 p. ct.; from fat, 6 p. ct.; from carbohydrates, 



89 p. ct. 



Basal values (February 14, 1910): CO 2 , 22 grams; Oa, 20 grams; heat (computed), 66 cals.; res- 

 piratory quotient, 0.81. Nitrogen in urine, 0.33 gram per hour.
