COST OF FOOD
FOODS DIFFER GREATLY IN COST.—One pound of rice costs much less than one pound of beefsteak. One cut of meat may cost less per pound than another. Twenty-five cents buys much less in weight of sweetbreads than of beefsteak.
Many factors other than difference in cost must, however, be taken into consideration when determining the value of foods.
COST OF FOOD IN RELATION TO NUTRITIVE VALUE.—Foods differ in nutritive value per pound. One pound of dried split peas contains more than three times as much nutriment as one pound of fresh peas. The nutritive value of a pound of sweetbreads is much less than that of a pound of beefsteak.
