In Tables VIII. and IX. it is seen how closely the diets are 
related in the percentage of the different food-materials taken. 
Table IX. shows that the total food ingested varied only from 
2168 to 2696 grammes per man per day. There is also great 
similarity in the relative amount of individual groups of food-stuffs. 
This is more marked, as one would expect, in the animal food- 
materials. Cereals, fruits, etc., are more likely to vary with chance 
circumstances, such as the menu for the particular week of study. 
This is seen in Table VIII. most markedly with regard to fruits. 
In Study A, fruit is 4’3 per cent, of total food consumed ; while in 
Study C 0'9 per cent, of fruit is present, with the high cereal figure 
of 2 1 *3 per cent. 
(F) Waste. 
Tables X. and XI. show that the waste varied very considerably. 
The proteid waste varied from 3 5 per cent, to 8 per cent, of the 
proteid purchased. A similar variation is seen in the fat waste — 
from 5*6 per cent, to 11 per cent, of the total fat. The high 
proteid and fat waste are found together as they represent the 
waste in animal food-stuffs — beef and bacon, etc. The percentage 
of unused carbohydrate is lowest as 0*5 per cent, and highest as 
10*2 per cent. In this case, the carbohydrate waste is chiefly in 
bread and potatoes. 
The cost of the waste materials can only be given approxi- 
mately. The lowest estimate is 0 31 pence per man per day, 
and the highest is associated with high proteid and fat waste, 
and is given as 1*2 pence. Stated in another way, the price of 
waste material varies from 2-4 per cent, to 7 per cent, of the total 
money expended on food.
