The nutriment should be forced eight to ten inches up into the rectum to insure absorption. This can be done by using a small injection point on a rubber tube and gently and patiently turning it as it is inserted. The tube may be oiled to prevent irritation. * * * * * [Sidenote: Derangements of the Liver] The liver is not, in a strict sense. a digestive organ, but it is very dependent upon them, as all products of digestion must pass through it and the starches, sugars and proteins, after they enter the blood, undergo chemical changes here. For a fuller understanding of the reasons for the following suggestions regarding diet for the liver, the writer would request a re-reading, at this point, of the chapter upon the “Work of the Liver” upon pages 81 to 92. It will be recalled that the liver acts, not only upon proteins, sugars, and starches,—the nourishing foods, but it also stands guard over poisonous ferments, due to putrefactions absorbed from the intestines, rendering them harmless; to a limited extent it also oxidizes the poisons of alcohol. The fats also pass through the liver. Since all products of digestion must pass through this organ, it is easy to see how it may be overworked, for it is an undisputed fact that most people eat more food than is required to maintain the body in nitrogenous equilibrium and to supply the necessary heat and energy. After the gorging of a heavy meal, the overloaded blood and liver express themselves in a sluggish brain and one feels mentally, as well as physically, logy, or overloaded. Since both sugar, carbohydrates and protein undergo chemical changes in the liver, it is evident that a diet consisting of an excess of either, must overwork the liver, not only through the nutritive food elements absorbed, but through the toxic substances which must be absorbed,—due to the excessive amount of food not being digested as readily as a smaller amount. If the food remains in the intestines too long, it is attacked by the bacteria always present there, fermentation results and poisons are absorbed and carried to the liver, where they must be broken down and rendered harmless, so as not to affect other parts of the system. If for any reason the liver is diseased, overloaded, or its action is sluggish, it will not promptly oxidize these toxins. One of the most important corrective agencies for an inactive liver is exercise directed to this organ, to bring a free supply of blood, and deep breathing of fresh air. _It is apparent that the blood must carry its full quota of oxygen to assist in oxidizing both the nitrogenous waste and the poisons_; and it must be remembered that the liver must oxidize the waste from its own tissues, as well as from other parts of the system.
