The Daily Food of a Model Man.
A healthy man, weighing, say, one hundred and fifty-four pounds, consists of water one hundred and nine pounds, and of solid matter forty-five pounds. His blood weighs about twelve pounds, or, when dry, two pounds. The quantity of food substances he should consume every day, and their relative proportions necessary to keep him vigorous and well, are stated by Prof. Johnston to be about as follows:
| lbs. | oz. | |
|---|---|---|
| Water | 5 | 8-3/4 |
| Albumen, fibrin, gluten, etc. | 4-1/4 | |
| Starch, sugar, etc. | 11-1/2 | |
| Fat | 3-3/4 | |
| Common salt | 3/4 | |
| Phosphates, potash salts, etc. | 1/3 |
If for a time the proper balance of constituents is not preserved in the food, even though the health may not appear affected, the laborer can do less work, a frail constitution is engendered and the person becomes more susceptible to disease.
