Therefore, we obtain the following information :—

| Burma rice | 12 | ozs, | + | Mung | dal | 6 | ozs. | Diet I. | 10.05 | ||
| Wheat ata | 10 | „ | „ | „ | 5 | „ | Diet II. | 9.09 | |||
| Vegetables | 6 | „ | „ | „ | 4 | „ | Diet III. | 8.08 | |||
Again showing that the maximum absorption is obtained from a diet consisting of
12 ozs. Burma rice, 10 ozs. wheat ata, 6 ozs. vegetables when 6 ozs. of mung dal is
given, and that a reduction of the amount of dal is followed by a corresponding
reduction in the quantity of nitrogen absorbed. We give on Chart XIII the figures
for the varying amounts of mung and arhar dals plotted out to show the effects
graphically.
By working out the percentage protein absorption of mung dal from the diets
given on Table XXI it will be found to average 85 per cent.—a much higher figure
than can be obtained when the quantities of rice in the diet are greater than 12 ozs.
per man daily.
As we have already pointed out this may not be entirely due to a high protein
absorption from the dal alone—although in this particular type of diet it probably
is. In all likelihood an increased absorption takes place from the constants of the
diets so that a seemingly greater increase occurs from the varying constituents
than is really the case; this is particularly the case when we are dealing with
a bulky material like rice as the varying constituent of the diet.
This finishes all we have to say regarding section (3) or the effects of varying
the quantities of the components of the Behari type of diet.
It will be evident from a comparison of these results with those obtained from
the dietaries of lower Bengal jails that the Behari is on a higher level of nitrogen-
ous metabolism, and in accordance with this we find his physical development,
body weight, and general capabilities of performing work and resisting infection also
on a higher level. The great defect of the Behar jail diet is the same as that of the
lower Bengal diet—the large residue left over to be dealt with by the bowel with
all its attendant disabilities. It is not therefore to be wondered at that intestinal
troubles are very prevalent amongst the Beharis as well as amongst the Bengalis and
Ooriyas.

| Description | The India Papers collection contains publications of the central (Imperial) Government and many Indian states. Most states came under British rule. Much of the collection dates from between the post-Mutiny re-organisation of the Indian Government and Indian Independence in 1947. Some items published in London by John Murray. |
