Protein contains nitrogenas the essential element in tissue-building.The white of egg and the lean of meat affordthe most familiar examples of protein. Theyconsist entirely of protein and water. Butmeat and eggs are not the only foods high inprotein. In fact, most ordinary foods con-tain more or less protein. The chief excep-tions are butter, oleomargarine, oil, lard, andcream — which consist of fat (and water)—and sugar, sirups, and starch, which consistof carbohydrate (and water),proportion of Foods should be so selected as to give tothe ration the right amount of protein, orrepair-foods, on the one hand, and of fatsand carbohydrates, or fuel-foods, on theother. A certain amount of protein is abso-lutely essential. While, for a few days, pro-tein may be reduced to little or nothing with-out harm, if the body be long deprived of theneeded protein it will waste away and ulti-mately death will result. Therefore, toolittle protein would be a worse mistake thantoo much. (36) Protein

fWJ W( Samuel Hopkins Adams *2) FOOD The right proportion of protein has beenthe subject of much controversy. Accordingto what are regarded as the best investiga-tions, it is generally about 10 per cent, of thetotal number of heat-units consumed. Thisdoes not, of course, mean 10 per cent, of thetotal weight nor 10 per cent, of the totalbulk, but 10 per cent, of the total nutriment,that is, 10 calories of protein out of every100 calories of food. Most persons in America eat much moreprotein than this. But that 10 calories out of100 is not too small an allowance is evidencedby the analysis of human milk. The growing Human MUkinfant needs the maximum proportion of pro-tein. In the dietary of the domestic animals,the infants food, the mothers milk, is richerin protein than the food of the grown animal.Consequently an analysis of human mothersmilk affords a clue to the maximum proteinsuitable for human beings. Of this milk 7calories out of every 100 calories are protein.If all protein were
