Food should have a pleasant taste while it is being eaten, but should not taste afterwards. If it does it is a sign of indigestion following overeating, or else it indicates improper combinations or very poor cooking. Perhaps food was taken when there was no desire for it, which is always a mistake. Perhaps too many foods were combined in the meal. Or it may be that there was not enough mouth preparation. It is generally due to overeating. Cabbage, onions, cucumbers and various other foods which often repeat, will not do so when properly prepared and eaten in moderation, if other conditions are right. Eructation of gas and gas in the bowels are indications of overeating. More food is taken than can be digested. A part of it ferments and gas is a product of fermentation. A very small amount of gas in the alimentary tract is natural, but when there is belching or rumbling of gas in the intestines it is a sign of indigestion, which may be so mild that the individual is not aware of it, or it may be so bad that he can think of little else. When there is formation of much gas it is always necessary to reduce the food intake, and to give special attention to the mastication of all starch-containing aliments. Also, if starches and sour fruits have been combined habitually, this combination should be given up. Starch digests in an alkaline medium, and if it is taken with much acid by those whose digestive powers are weak, the result is fermentation instead of digestion. People should never eat enough to experience a feeling of languor. They should quit eating before they feel full. If there is a desire to sleep after meals, too much food has been ingested. When drowsiness possesses us after meals we have eaten so much that the digestive organs require so much blood that there is not enough left for the brain. This is a hint that if we have work or study that requires exceptional clearness of mind, we should eat very moderately or not at all immediately before. The digestive organs appropriate the needed amount of blood and the brain refuses to do its best when deprived of its normal supply of oxygen and nourishment. Serpents, some beasts of prey and savages devour such large quantities of food at times that they go into a stupor. There is no excuse for our patterning after them now that a supply of food is easily obtained at all times. A bad taste in the mouth is usually a sign of overeating. It comes from the decomposition following a too liberal food intake. If water has a bad taste in the morning or at any other time, it indicates overeating. It may be due to a filthy mouth or the use of alcohol. Heartburn is also due to overeating, and so is hiccough; both come from fermentation of food in the alimentary tract.
