It would require .yj pounds of Grape Xuts iyi of a package) 

 to furnish V3 of the protein needed for one day for a man at 

 moderate work: the energy needed would be afforded by .63 

 pounds. 



The nutrients of beef are more completely digested and 

 absorbed than those of vegetable foods. There is no reason for 

 thinking that Grape Xuts would be more completely digested 

 than rolled oats, wheat flour or wheat bread. About 85 per 

 cent of the protein and of fuel value of vegetable foods are 

 digested and rendered available to the body. 



In the following table there are compared the pounds of pro- 

 tein and fuel values of one pound of Grape Xuts with ''''ten 

 pounds of meat, wheat, oats or bread. "
