    o DIET AND FOOD—CHAPTER I upset* her methods without the power of substi- tuting more satisfactory ones and suffered in consequence from many unexpected and terrible results of his rashness. As one of these many men are attempting to carry the diet of youth into middle life and age, and the diet that was suitable for an active outdoor life into a life of sedentary office work. If they fall into neither of these errors they are generally completely ignorant of the relative value and importance of foods, so that they either starve themselves on vegetables and herbs con- taining little or no albumen, or, on the other hand, over-feed themselves on concentrated albu- minous foods. To prevent such mistakes and to substitute a certain amount of scientific precision for the previous rule of thumb methods is the object of this little book, and we may say as a beginning that the first essential of nutrition is the supply to the blood of sufficient albumen to replace that transformed into urea in the production of force. If food is withheld urea goes down and down, and with it falls the power of producing force in active exercise. Fig. 1 shows in a curve the hourly excretion of urea in the sixteenth, fifteenth, fourteenth and earlier hours of a fast, no food having been taken since 8.30 p.m. on the previous day.
