The term "appetite" is ordinarily used by the median someone to' prescription the desire for food. Appetite is genuinely a combination, consisting chiefly of the sensations of taste and smell. Its causation is not fully understood, and a complete explanation is more difficult to' give than in the case of hunger. Lack of food develops both hunger and appetite. Partaking of food allays both of these sensations. On a continued fast, the appetite is considerably diminished but the sense of hunger remains. The duct of food straight through the oesophagus satisfies the appetite, but hunger may still exist. Emptying the stomach revives the appetite but hunger does not always immediately appear. Appetite is thus generally a sensory question based upon taste and smell; and when these are satisfied, the sensation disappears. This last point is of great practical value in several ways:
1. If very seasoned or sweet foods are eaten at the beginning of the meal, the appetite may be fully satisfied before sufficient food has been eaten to supply the nutritive needs. This is often seen with children who participate of desserts or Sweets before the rest of the meal starts.
2. By permanently using very seasoned food, a someone may lose his appreciation of the mare salutary articles of diet, and thus not be satisfied with the more nutritious foods.
3. One may eat plenty of good commonplace food, and after having a sufficient supply of nutritive material, so far as the body needs are concerned, be tempted by fine-tasting dishes which stimulate the appetite, and thus be led to overeat. This is a very coarse practice.
4. The use of strong-tasting foods may call for stimulants to satisfy the cravings of the appetite. There is thus genuinely a specific association in the middle of the Use of very seasoned foods and condiments and the Use of alcoholic beverages, one calling for the other.
5. Inordinate Use of sweets has an sway not fully realized by people generally. Children construe this point very nicely. Those who indulge in sweets often do not relish their food unless it is sweetened excessively. This may go on to the point where the child does not care for primary foods. He thus develops a "peculiar appetite," as people sometimes say, and his parents are not able, to understand his dislike for coarse articles of diet.
