INFLUENCE OF FOOD PRESERVATIVES ON HEALTH. 



SUMMARY. 



The summary by periods only for the niixe men completing the series 

 is given in the table following, the averages having been taken from 

 Table XXIII (page 689), giving the solids balances in full: 



TABLE XXII. Solids summary, by periods, for nine men, Series VL 



The average daily amount of solids consumed increased slightly from 

 period to period, there being an increase of 9 grams in the preserva- 

 tive period and 4 grams additional increase in the after period. The 

 largest percentage of solids in the feces is found in the fore period, 

 namely, 3.92 per cent, and the smallest in the preservative period, 

 namely, 3.46 per cent, while the quantity in the after period is 3.59 

 per cent. The smallest percentage of solids in the urine is found in 

 the fore period, namely, 10.75 per cent, while the quantities in the 

 preservative period and the after period are almost identical. The 

 largest balance is found in the after period, namely, 485 grams daily, 

 the smallest in the fore period, namely, 474 grams daily, while the 

 balance for the preservative period is almost the same as that of the 

 after period, namely, 483 grams daily. 



These data show a tendency on the part of the preservative to increase 

 the absorption from the alimentary canal of the solids in the food, as 

 shown by the decrease of solids in the feces, and also to increase the 

 katabolic activities of the body as indicated by the increased excretion 

 of solids in the urine.
