Now, when we turn to dairy products and to the vegetable kingdom for our fats, we find that a very large amount of fat is contained in a number of articles of diet—far greater than in any of the fattest meats. Thus, butter contains 85 per cent. fat; American cheese, 38.3 per cent. fat; California cheese, 33.4 per cent. fat; cheddar cheese, 36.8 per cent.; cream cheese, 58.0 per cent.; full cream cheese averages 33.7 per cent.; old English cheese, 42.7 per cent.; etc. Cream, on the other hand, contains less than we should suppose, being but 18.5 per cent. fat, and milk only 4.0 per cent. fat. Our great source of fats, however—leaving out all dairy products, which, it might be claimed, are indirectly derived from the animal kingdom—is nuts. The great value of these articles of food will become apparent to us when we see that not only are they at the head of the list in protein percentage and in fuel value, but also in the percentage of their fats. Thus we find almonds average 54.9 per cent. fat; beech-nuts, edible portion, 57.4 per cent.; Brazil-nuts, edible portion, 66.8 per cent. fat; butter-nuts, 61.2 per cent. fat; cocoanuts, 50.6 per cent. fat; filberts, 65.3 per cent.; hickory-nuts, 67.4 per cent.; peanuts, 38.6 per cent.; pea-nut butter, 46.5 per cent.; pecans, 71.2 per cent.; pine-nuts, 60.7 per cent.; California walnuts, 64.4 per cent.; black California walnuts, 53.3 per cent.; soft-shell walnuts, 63.4 per cent. Chocolate also contains 48.7 per cent. fat. If now we compare with these figures those “highly nutritious” invalid foods, meat soups, etc., we find the fat percentages to run as follows:—Beef soup, .4 per cent. fat; chicken, .8 per cent.; clam chowder, .8 per cent.; and meat stew, averaging 4.3 per cent. fat. Let us now compare the relative percentages of carbohydrates. In the majority of meats these are so very low that it might almost be said they contain no carbohydrates at all. In the above tables from Atwater and Bryant’s analysis, it will be seen that no figures at all appear in the column for carbohydrate percentages. With the single exception of tripe, which contains an average of .2 per cent., no mention is made of a percentage of carbohydrates in any of the meats. Hens’ eggs also contain practically none. Poultry and game, when cooked, average from 2 per cent. to 5 per cent.; fish contain practically none, while shellfish range from 1 per cent. to 3 per cent. This is all the carbohydrates that the animal kingdom affords us! Turning now to dairy products, we find that various cheeses furnish from 2 per cent. to 4 per cent. carbohydrates; milk averages 5 per cent., but condensed, unsweetened milk, or evaporated cream, average 11.2 per cent. It will be seen, therefore, that dairy products, coming as they do, indirectly from the animal kingdom, furnish a comparatively small percentage of carbohydrates.
