INGESTION OF CARBOHYDRATES.

indicate an increment in metabolism as a result of the ingestion of 

 sugar. As a rule, the respiratory quotients were characteristically 

 high. The basal value used for this experiment was an average of 

 four values, one obtained on the morning of the same day and the 

 others determined at intervals in the following three weeks. The 

 total increments of 18 grams of carbon dioxide, 4.5 grams of oxygen, 

 and 19 calories of heat over the basal value in the course of 5 hours show 

 a definite effect on the metabolism as a result of the ingestion of sugar. 



TABLE 103. F. M. M., January 31, 1910. Sitting. (1-hour periods.) 



Sucrose: 



Amounts, 100 grams sucrose, and juice of one lemon; energy, 408 cals.; from carbohydrates, 



100 p. ct. Nitrogen in urine, 0.53 gram per hour. 



Basal values (January 31 to February 19, 1910) : COt, 26.5 grams; 62, 23.0 grams; heat, 1 80 cals. 

 On January 31, 1910, respiratory quotient, 0.86; nitrogen in urine, 0.54 gram per hour. 



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