 TABLE I. Continued. 



a Fruits contain a certain proportion of inedible materials, as skin, seeds, etc., which are prop- 

 erly classed as refuse. In some fruits, as oranges and prunes, the amount rejected in eating is 

 practically the same as refuse. In others, as apples and pears, more or less of the edible material is 

 ordinarily rejected with the skin and seeds and other inedible portions. The edible material which 

 is thus thrown away, and should properly be classed with the waste, is here classed with the refuse 

 The figures for refuse here given represent, as nearly as can be ascertained, the quantities ordina 

 rily rejected,

 The average in the table represents the available nutrients in the beverage. Infusions of genuine 

 coffee and of tea like the above contain practically no nutrients. 



PROPORTIONS OS NON-NUTRIENTS IN FOODS. 



It will be interesting to note some of the differences in food 

 materials as shown by their composition. One of the first things 

 which may be observed when a table like the above is studied, is 

 the differences in the proportions of non-nutrients, i. e., refuse and 

 water. Many kinds of food as they are purchased contain large 

 amounts of refuse, which necessarily lessen the proportion of nutri- 

 ents. Such refuse is usually absent in the dairy products (milk, 

 butter, cheese, etc.), dried vegetables, cereal foods (flour, breakfast 

 foods, etc.), and the bread, cakes, and other foods prepared from 

 them. In considering the edible portion we find that the amount of 

 water present also affects the nutritive value of food. Water is
