Water as a Regulative Food. Have you ever stopped 

 to think how important water is to living things ? Seeds 

 cannot sprout and plants cannot grow without it : all 

 animals are dependent upon it and soon die if their supply 

 is cut off. The human body is over 65 per cent water. 

 Body cells cannot do their work without it, for chemical 

 changes cannot take place unless water is present. Water 

 usually contains mineral salts which are necessary for life. 

 It helps regulate the temperature of the body, it helps 

 dissolve foods so they may be absorbed by the cells, and 

 it aids in the passing off of wastes from the body. Al- 

 though we take a good deal of water into the body with 

 our foods, for example, in fruits, milk, and other beverages, 

 it is a good plan to get the habit of drinking 5 or 6 glasses
