Excerpt from A Laboratory Hand-Book for Dietetics Only brief statements of the conditions affecting food require ment have been made, the reader being referred to general text books on the subject of nutrition for fuller information, but such data have been included as seem most useful in determining the amount of food for any normal individual under varying conditions of age and activity. Most of the available information in regard to food values is in terms of percentage composition, or of a single unit, as the 100 Calorie portion or the individual serving. The two latter are very useful, but too limited in scope and too inelastic in form to serve the needs of the general student. The former involves calculations which are always tedious and rob the student of time for a more comprehensive comparative study of food values. To lighten this labor, tables are included, giving the food values for the loo-calorie Portion, which is taken as the Standard Portion in the sense that it serves as a convenient unit in building up a day's ration to yield a stated number of Calories; for the gram, which is the unit of weight for all scientific workers; for the ounce, the common unit of the small family group; and for the pound, the unit of the large family or institutional group. These tables have been in practical use for several years in the author's classes, and their value in relieving the student of monotonous clerical labor has been demonstrated.
