58 MILK SURVEY OF THE CITY OF ROCHESTER 



A. I am inclined to hold that belief; one cannot establish at the 

 present time such a view, but there is considerable evidence that that is 

 the case. I can give you a few examples perhaps which will illustrate 

 why I believe that. About the tenth to the twelfth and thirteenth cen- 

 turies there was a great invasion of Europe as far as the Danube and of 

 China by the Mongol hordes of Central Asia. Now, the Chinese are a 

 people who do not or did not use dairy products ; they used as their sole 

 protective food, as their principal protective food, leaves to cure the de- 

 ficiencies of their diet; they had used eggs in considerable amount, but 

 they did not use dairy products. I have mentioned the fact that these 

 people have not progressed in science, literature and art to the extent 

 that certain other people have, but they have furthermore been overrun 

 by hordes from the North and Northwest, rapidly succeeding invasions 

 from the North and West throughout the period of history, and the peo- 

 ple who have overrun China so many times are the Mongol hordes of 

 Central Asia who are keepers of flocks and herds and whose principal 

 article of diet is sour milk. They have overrun and been a thorn in the 

 side of Russia up to within the last five or six hundred years ; they over- 

 ran the country as far West as the Danube in the thirteenth and four- 

 teenth centuries. 



The ancestors of the Turks were successful in war, extending their 

 conquest westward, and lived on a diet of fruit and sour milk. The Arab 

 living in a hot climate, in a climate whose daily temperature at noon fre- 

 quently rises far beyond 100 degrees, lives largely on sour milk. They 

 have camels' and goats' milk to some extent and to some extent cows' 

 milk. Those people live largely on sour milk and on such a diet they not 

 only live in the Torrid Zone, but they have energy, endurance and courage 

 to traverse the weary caravan trails of the desert under a burning sun. 

 The people of Europe and America have been great users of dairy prod- 

 ucts, and they and the very few other people in places where new coun- 

 tries have been settled by descendants of Europeans have reached the 

 highest stage of civilization; have cultivated the best system of religion 

 that we know of ; have advanced furthest 'in scientific attainments, in 

 literature and art and music and all lines of achievement of the human 

 intellect. I believe these statements can scarcely be successfully con- 

 troverted, and if there is anything wrong with them, I have been unable 

 to learn it. 



Q. Well, do you believe that after an adult has attained full growth 

 that it makes any difference from that time on whether the diet includes 

 dairy products or not ? 



A. It certainly does in the case of all types of experimental animals 

 of the omniverous type with a limited capacity of digestive tract with 

 which to work.
