a fuel value of 1950 for cream cheese. As against the figures just quoted, let me cite two or three analyses of meat soups, which have frequently been administered to invalids under the idea that they are “strengthening” and “heating”—thus supporting or maintaining the temperature and the energy of the sick person. Apart from the fundamental error contained in this theory—that we _do_ derive our strength and the heat of the body from the food eaten (which I have endeavoured to prove incorrect in my “Vitality, Fasting and Nutrition,” pp. 225-303; 332-350; 448-459; etc.), there is the direct evidence afforded by the chemical analysis of these articles of diet. As opposed to an average of more than 20.0 protein percentage, and a fuel value averaging more than 1600 calories, we find for beef soup, as purchased, a protein percentage of 3.2 and a fuel value of 295; a protein percentage of 1.8, and a fuel value of 195, for clam chowder; and a protein percentage of 4.6 and a fuel value of 370 for ordinary meat stew! Quite apart, therefore, from the argument based upon the fact that all meat juices and extracts contain, in addition to the nutritious principles, a large amount of poisonous or toxic material, we have here direct evidence of the fact that these meat soups, so generally administered to invalids, are totally lacking both in high protein value and in fuel value; and when we consider that, in addition to all this, they contain a large amount of poisonous matter in solution, it will be seen how false is the doctrine of administering soups of this character to patients, under the impression that we are helping them to sustain their bodily heat, their energies and their strength!
