28 NUT GROWING 



"Satisfactory growth was observed in young rats 

 on diets in which the almond, English walnut, filbert, 

 and pine nut, respectively, furnished the essential 

 source of protein in the ration. 



"Normal growth can be secured when rats are fed 

 upon otherwise adequate diets containing the almond, 

 English walnut, black walnut, Brazil nut, chestnut, 

 or pecan as the sole source of water-soluble vitamine. 

 Animals which have declined on a diet devoid of 

 water-soluble vitamine promptly recover when the 

 almond, English walnut, filbert, hickory, pine nut, 

 chestnut, or pecan is introduced in the diet. These 

 observations indicate that nuts are sources of abun- 

 dant quantities of water-soluble vitamine. 



"The proteins of the almond, English walnut, pine 

 nut or filbert furnish the necessary nitrogenous com- 

 plexes for the elaboration of milk in rats." 



The practical question in relation to nuts includes 

 the idea that they contain not only the elements re- 

 quired for human food supply, proteins, oils, 

 starches, but also the vitamines. Vitamines have not 

 as yet been described chemically, but they are the 

 factor which gives zest to the eating of food, and 

 constitute a vital factor in our body chemistry. The 

 measurable calories of nuts allow us to place the dif- 

 ferent kinds in the ration where they belong. 



I remarked to a guest at the farmhouse who was 

 eating some crisp red watermelon fresh from the 

 garden and ice-box, that it did not contain many 

 calories. This young miss replied that she did not 

 want calories, that all she wanted was watermelon.
