SUMMARY OF THE RESULTS OF DIETARY STUDIES REPORTED BY 
THE STATION, 
Table 45 gives a summary of the results of forty-one dietary 
studies reported in the present and previous Annual Reports 
of this Station. ‘These are for convenience arranged into five 
groups: those of farmers’ families, those of mechanics’ families, 
those of the families of professional men, those of College stu- 
dents’ clubs, and finally those which do not naturally come 
into either of the above classes. For the sake of comparison 
the average of each group is given. 
The results are in all cases calculated to the same basis, ‘‘ per 
man per day.’’ Accordingly the figures for the College ladies’ 
club represent larger quantities than were actually consumed. 
If they are multiplied by 0.8, the results will be the values 
‘“ner woman per day,’’ and will represent the amounts actually 
consumed in this study. 
In each dietary the nutrients and fuel value, ‘‘ per man per 
day,’’ of the food purchased, wasted, and eaten, are shown 
together with the estimated digestible nutrients in the food 
eaten and its fuel value. ‘These digestible nutrients were esti- 
mated by the use of the factors explained beyond. 
The results of study 179, described beyond, are included in 
the summary table but are not in the averages. |
