Research 2. On the most Economical Lines upon which to Construct Diets 
having the same Nutritive Value as our Standard Diet. 
In view of the large expense of dieting in most sanatoria, and in order to 
bring the modern dietetic treatment of tuberculosis within the reach of the 
poorer classes, we made a series of observations, with a view to determining 
the most economical lines upon which an adequate diet can be constructed. 
An Economical Diet—An analysis we made of physiologically adequate 
diets, taken by 100 working-class families, showed us that an adequate diet 
for the working classes can be bought for about 10d. a day, and that, in such 
a diet, every penny spent buys some 12°7 grammes of proteid and 329 calories. 
The average of these 100 satisfactory diets worked out at: proteid, 119; fat, 
114; carbohydrate, 417; calories, 3687; at a cost of 10d. (not including 
money spent upon beer or other alcoholic drinks). 
The aim of our work was to increase this average diet some 30 per cent. in 
proteid without appreciably increasing the cost. 
During the course of our preliminary observations on the subject, we 
found that the convalescent working-class consumptive, when taking a con- 
siderable amount of exercise, such as digging in the gardens, etc., requires a 
larger diet than our standard diet for men at physiological rest, and we 
aimed, in consequence, at constructing a diet with a nutritive value of 
Proteid. Calories. 
150 and 3600 approximately. 
A trial of several dietaries of the above nutritive value, and constructed 
on the lines of ordinary dietaries, showed us that the expenditure on meat. 
accounted for some 40 per cent. of their total cost, and that, to construci a 
really cheap diet, the amount of animal proteid, especially meat, must be 
kept down as much as possible, and considerable use made of the cheaper 
forms of vegetable proteid, such as peas, beans, lentils, etc. We estimated 
that the replacing of meat by vegetable proteid would prove an economy of 
30 per cent. 
In view of the widely accepted principle that animal proteid, especially 
meat, has some specific value in the treatment of tuberculosis, and may even 
be regarded as an essential in the diets for the tubercular, we decided first to
