To feed under such conditions causes the temperature to rise and the pains and general discomfort of the patient to increase. Much of the restlessness and uneasiness usually observed in fever patients of all kinds is due to feeding and drugging. The fasting patient is comparatively comfortable and rests well, and makes a more rapid and satisfactory recovery.
Dr. Jennings says: "The more you feed a sick man, the sicker you make him." Again, "Don't aggravate the troubles of a sick fellowman by forcing him to swallow food against the protest of his stomach."
Let us see what happens if we feed in acute "disease." The first thing the patient and physician note is an increase in symptoms. The fever goes up, the pulse increases, pain and other symptoms become more intense; the patient is caused much unnecessary suffering, and the patient's relatives are caused much needless anxiety.
Graham declared that "the more they nourish (feed) a body while diseased action is kept up in it, the more they increase the disease." Again "when the body is seriously diseased * * * entire and protracted fasting would be the very best means in many cases of removing disease and restoring health. I have seen wonderful effects result from experiments of this kind."--Science of Human Life. He also called attention to the fact that eating increases the pain, inflammation, discomfort, fever and irritableness of the sick and that it does so in proportion to the amount of food eaten and in direct ratio to its supposed nutritive qualities, while fasting reduces the "violence" of the "disease" and renders recovery more certain. All forms of acute disease are cut short and made comfortable by fasting. Fever rapidly abates and inflammation quickly subsides.
