Many foods disagree at certain times because of the particular conditions regulating the secretion of digestive juices. When this condition has continued for some time it becomes chronic and a special diet is required, together with special exercises, to bring a better blood supply to stomach and intestines and to regulate the nerves controlling them, in order to correct the abnormality.
One may so form the habit of criticism or of being disgruntled or thinking he cannot eat this food and that, that his entire system suffers. Much indigestion is more mental than physical.
Effect of the Circulation
It can be readily seen that any tissue, playing so important a part in digestion as the blood, needs to be kept in as nearly perfect condition as possible. A vigorous circulation stimulates digestion; a poor circulation retards it.
If the blood is poor in quality the digestive organs are not nourished and the digestive secretions are lessened in quantity and quality.
If the blood is imperfectly aërated it carries an insufficient supply of oxygen, combustion is lessened, and the waste, not being in a condition to be removed, remains in the tissues, stagnation results, and a slow poisoning process goes on which gradually causes the system to fail to meet the demands made on it.
The blood tissue can only be kept in condition by an adequate but not excessive amount of good food taken at the proper time, and such active exercise as will thoroughly aërate the blood by bringing the air to the smallest air cells in the lungs.
If one would fight to prevent the money used in daily exchange from being debased, he ought to be much more ready to use every means in his power to prevent a deterioration of the blood, that medium of exchange in his body on which such vital issues depend.
