DISCUSSION OF THE DIETARIES. 
In the study of a fruitarian diet previously published a it was noted 
that the foods used were almost exclusively fruit and nuts, the latter 
being the main sources of protein and fat, while the fruit furnished 
the bulk of the carbohydrates, consisting chiefly of the different 'sorts 
of sugar, with considerable crude fiber and a small amount of starch. 
All the food was eaten raw. The cost of the diet varied from IT cents 
to 27.5 cents per person per day, and was on the average 20.7 cents. 
Both the protein and the energy in every case were far below the 
limits called for by the tentative American standards for persons per- 
forming a like, amount of muscular work. Xo general conclusions 
were drawn, as the data did not seem sufficient to warrant them. An 
examination of the data recorded above will show that the present 
studies agree essentially with those previously reported. 
In discussing the general question of a fruitarian diet it is of interest, 
for purposes of comparison, to quote the results obtained by other 
investigators in studies of a vegetarian diet with subjects whose daily 
fare included a considerable amount of fruit and nuts. 
Voit^ studied the dietary of a vegetarian 28 years old, height 5 
feet 5 inches, weighing 125 pounds, whose average dailv diet con- 
sisted of 131 grams pumpernickel, 438 grams graham bread, 777 grams 
apples, 114 grams dried figs, 247 grams dates, 66 grams oranges, 8 
grams olives, and 21 grams olive oil. 
Ten years later Rumpf and Schumm- reported a metabolism exper- 
iment with a vegetarian 19 years old. weighing 138 pounds, whose 
daily consumption of food was as follows: 330 grams graham bread, 
1,100 grams apples, 260 grams dates, 14<) grams Quaker Oats, 100 
grams rice, 75 grams sugar, and 30 grams nuts. 
Albu, rf in 1901, made a digestion experiment lasting five days, with 
a vegetarian, a woman, 42 years old, whose weight was 83 pounds and 
height 4 feet 3 inches. Her average daily diet included 12<> grams 
graham bread, 400 grams apples, 400 grams plums, 200 grams grapes, 
64 grams nuts (without shells), 170 grams dates, and 100 grams lettuce. 
The same author reports a twelve-day dietaiy study of one of the 
leaders of the vegetarian movement in Germany, a man 48 years old, 
height 5 feet 8 inches, weighing (with clothes) 153 pounds. The aver- 
age daily diet consisted of 1,000 grams potatoes, 166 grams hazelnuts, 
12.5 grams peanuts, 83 grams plums, 71 grams sugar, 93 grams raisins, 
354 grams apples, 63 grams oranges, and 50 grams olive oil.
