THE PROPER DIET. 12 J 



body (p. 82) to keep up the animal heat. If food be 

 eaten slowly, the natural appetite is, in health, a safe 

 guide. Those who injure themselves by over-eating, are 

 not the workers who come to their meals hungry, but the 

 indolent who, having little appetite, stimulate their pal- 

 ates by highly flavored food, to enable them to eat what 

 they have not earned, and their bodies do not want. 



An over-distended stomach is not merely injured it- 

 self, but interferes with the heart and lungs. It pushes 

 the diaphragm up against them and impedes their move- 

 ments. Hence result feelings of oppression in the chest, 

 shortness of breath, and faintness. Palpitation of the 

 heart may also be produced : it is frequent in that kind 

 of dyspepsia which is accompanied by accumulation of 

 gas in the stomach. 



9. A Proper Diet contains both Animal and Vegetable 

 Foods. The teeth of a purely flesh-eating animal, as a 

 tiger, are constructed only for tearing and cutting. 

 Those of a vegetable-eater, as a cow, are very broad 

 and constructed for grinding, except a few in front for 

 cropping grass. Man's teeth are half-way between the 

 purely flesh-eating and purely vegetable-eating kind. 

 Their structure shows that our proper food is both 

 animal and vegetable. 



This is also proved by the fact that some of the 

 digestive liquids found in the human alimentary canal 

 are, like the saliva (p. 106), especially fitted to digest 



said concerning those who injure themselves by over-eating? Conse- 

 quences of an over-distended stomach? What is said concerning 

 palpitation of the heart ? 



9. Teeth of a purely flesh-eating animal ? Of a vegetable-eater ? Of 

 man ? What does their structure show ? How is this also proved ? 

 When should less animal food be taken ?
