CHAPTER VHI. 



' MODIFIED MILK. 



Use of Modified Milk. The normal healthy adult 

 does not need this class of milk. But the ability of the 

 infant, the invalid, and persons suffering from indigestion, 

 is at times such that normal milk may not be properly 

 digested and assimilated. Hence, it becomes necessary 

 to modify this natural product to meet the requirements 

 of these individuals. 



Although the quantity of this grade of milk consumed, 

 like certified milk, is very small compared with the great 

 bulk of regular market milk, it is of great importance, 

 because of its extensive use for infants. 



Digestibility of Modified Milk. The modification of 

 milk for infant feeding owes its origin and present use to 

 the fact that normal cow's milk frequently cannot be 

 properly digested by an infant. This is due, first, to 

 cows' milk having a different composition from that of 

 human milk; and, secondly, to the fact that some infants 

 have weak digestive systems and therefore require milk 

 of special composition. Therefore, it becomes necessary 

 so to alter the composition and the physical and chemical 

 properties of the milk that it may be properly digested 

 and assimilated. 



It is possible that the casein in cows' milk is too often 

 held to be responsible for digestive troubles in infants.
