FIFTY-THIRD ANNUAL CONVENTION 51 



drinking moonshine. If they are then fed the water extract 

 of rice polishings, the outer part of the rice kernel, in two or 

 three hours they will recover remarkably. This wonderful 

 recovery is due simply to the fact that the outside of the 

 rice kernel contains vitamin B. 



In our human diet in this country we do not need to 

 worry about the lack of vitamin B. Patent flour and pol- 

 ished rice are low in this vitamin. On the other hand, meat, 

 milk, vegetables, and many other foods are rich in it. 



The American Medical Association, after making a 

 thorough study of the matter, concluded there is no evi- 

 dence of a lack of this vitamin in the diet of the American 

 people. This is an important matter, for one of the large 

 concerns manufacturing yeast recently carried on an exten- 

 sive campaign in an effort to get farmers to feed yeast to 

 their livestock. In my opinion, there would generally be 

 no benefit from adding yeast to well-balanced rations fed to 

 our farm animals. 



Vitamin C 



So far as our present knowledge goes, the third vit- 

 amin, called vitamin ''C", or the anti-scorbutic vitamin, is 

 of little or even no importance at all in the feeding of all 

 classes of farm animals. This vitamin prevents the disease 

 called scurvy, which affects humans seriously when they 

 can get no fresh vegetables, fresh fruits, or other foods 

 containing this vitamin. 



Farm animals either do not require any of this vitamin, 

 or else they need only such extremely small amounts that 

 they always get plenty in their feeds. At least there is no 

 definite proof that farm animals ever have scurvy. 



In feeding humans, monkeys and guinea pigs, how- 

 ever, this vitamin must be furnished or scurvy will result. 

 The vitamin is supplied by fresh fruits, vegetables, milk and 

 fresh meat, but is low in the cereals. It is easily destroyed 

 by prolonged cooking or drying at high temperatures. It 

 is to furnish this vitamin that infants are so commonly fed 

 orange juice.
