86 THE PROTEIN ELEMENT IN NUTRITION 



Study 5. Dietaries of the hill-tribes of Bengal. 



Very accurate information was collected on the quantity and 

 classes of food materials consumed by these hill-men under 

 natural conditions. The investigations carried out and the 

 effects noted will necessitate detailed consideration in connection 

 with the relationship of food to physical development ; at present 

 we may simply record the dietaries. 



DIET I. TIBETAN BHUTIAS, BHOTAN BHUTIAS (DANDY CARRIERS, RICKSHA 

 MEN, AND COOLIES WHO PERFORM THE HARDEST WORK). 



Protein, 175 to 200 grins. Heat value, 6,300 to 6,500 calories. 



Of the protein element well over 60 per cent, is derived from 

 an animal source. It is not uncommon to find these men eating 

 as much as 2 pounds of meat daily. They are well paid and 

 live generously. Physically they are splendid specimens of 

 well-developed muscular manhood. As already mentioned, they 

 correspond to the ricksha men of Japan, and, like them, they 

 exhibit a great weakness for a liberal supply of food, and particu- 

 larly for animal protein. 



DIET II. TIBETAN LAMAS (PRIESTS AND THOSE WHO HAVE NOT SUCH HARD 

 WORK AS THE DANDY CARRIERS). 



Protein, 160 to 180 grms. Heat value, 4,000 to 4,250 calories. 



DIET III. GENERAL DIET or THE MORE POORLY-FED CLASSES WHO EARN 



LOWER WAGES. 



Protein, 150 to 160 grms. Heat value, 3,250 to 3,500 calories. 



DIET IV. DIET OF SIKHIM BHUTIAS (HARD-WORKING CLASSES). 

 Protein, 130 to 140 grms. Heat value, 3,200 to 3,300 calories. 



DIET V. DIET OF LEPCHAS (POORER CLASSES OF SIKHIM BHUTIAS). 

 Protein, 112 to 125 grms. Heat value, 3,500 to 3,800 calories. 



In all these dietaries a large part of the protein comes from 

 beef or mutton, up to 70 per cent., except in Diet V., the poorer 

 classes of Lepchas not being able to afford more than J pound 

 of meat daily, which provides about 50 per cent, of the total 

 protein of their dietary. Rice also enters more largely into the 

 diet of the Lepchas. 



DIET VI. DIET OF THE NEPALESE CHUTTRIES. 



Protein, 120 to 130 grms., of which less than 40 per cent, is derived from an 

 animal source.
