We will choose a woman in our own temperate climate 

 in good health, and doing a moderate amount of work. She 

 needs 3 1-2 ounces each of fat and proteid, and nearly 11 

 ounces of starches and sugars. It is found that a man needs 

 slightly more food than a woman, and the average house- 

 keeper has already stored away this information from her 

 own experience. And, that a man doing hard work needs 

 more, especially of the energy giving foods, than the man 

 doing little or no actual work. 



Children need slightly more of easily digested proteids, 

 because we must not forget that this is a season of growth 

 for them. Very old people need less food and should have 

 simple and easily digested foods. 



But someone has said, "It is not what we eat, but what 

 we digest, that really matters." In this age of food fads 

 it seems fair to speak a word on the subject. 



True, it matters little if a food contains a large per cent, 

 of nourishing food materials if they cannot be digested. 

 Aside, then, from the nutritive content of foods, we must 

 ■consider the digestive value. 



Baked beans contain practically as much proteid as 

 beef, but the indigestible, woody fibre of the outside coating 

 makes them far less easily digested than broiled or roasted 

 beef. In general, all vegetable proteids as in peas and beans 

 and nuts are less easily digested than the animal proteids. 

 This does not mean they should not be used — far from it — 

 but it does explain why the lumberman in the logging-camp 

 with his healthful, out-door life, thrives on a diet of baked 

 beans and pork, while the professional man at his desk must 

 forego even the luxury of his Saturday night baked beans, 

 so dear to the heart of every true New Englander. 



An easy method of classifying foods for the use of the 

 housewife groups them into the following classes: 



Light Tissue Builders: This includes foods which con- 

 tain proteid in some easily digested form, and the group is 

 to be used with young children, invalids, and with people 

 generally who lead a quiet, indoor life. 



The Hearty Tissue Builders are for general use with 

 all healthy folk, including older children, who get plenty of 

 ■exercise in the outdoor air . 



The Hearty Heat and Energy Givers are less easily di- 

 gested than the Light Heat Givers, and both classes are for 

 use as the tissue-building foods of the same class.
