If one were to choose for example, a diet of meat, eggs, nuts, corn starch, tapioca, sugar, fats and oils, i.e., diets which will be almost completely digested and absorbed, leaving a very small amount of undigested material in the intestines, the bulk of the material in the intestines would be so small that they would not be stimulated to contract. Therefore this small bulk of material, together with certain excretions from the liver and other organs, would be retained in the bowel and undergo fermentation there. Injurious substances which result from the fermentation would be absorbed, causing what is known as autointoxication, complicated with constipation. If one, however, mixes with the condensed foods named above a good proportion of cereals, fruits and vegetables, all of which possess a considerable percentage of undigestible material, the presence of this undigestible material in the intestines leads to strong peristaltic movements, causing the passage of this material along the intestinal tract to the rectum, which will be periodically evacuated. In such cereal foods as the coarser meals (like oatmeal, various wheat preparations and corn meal), the proportion of bran substance serves as a local stimulation to the intestinal activity. The little bran scales being sharp-cornered and rough, serve as a local irritant or mechanical stimulation. What has just been said regarding the advisability of eating some coarser cereals must not be taken to mean that white bread is not wholesome. On the other hand, white bread made from the roller process flour is in a high degree nutritious and wholesome, and may well make an important part of any dietary. It is not hygienic to eat white bread or biscuits hot out of the oven. These hot breads tend to form doughy masses which are almost completely impervious to the digestive juices, and while they are eventually digested, it takes a very much longer time to do so than would be the case with stale bread, which is so readily masticated into a creamy consistency. If one is subjected to conditions where he must either eat hot biscuits or perhaps embarrass a most hospitable hostess, there is only one thing for him to do, i.e., to eat the biscuits. It is possible, though difficult, to masticate hot bread so perfectly that it is reduced to a smooth, creamy consistency, and no one should ever swallow any bread which has not been so masticated. Among the fruits, figs, prunes and apples seem to have the most clearly marked laxative effect, though all ripe fruits generally, and especially those that are taken uncooked, have a moderate laxative effect. Belonging to this class of foods is rhubarb which, though not a fruit, is usually served as a fruit either stewed or in puddings or pies. There is no doubt that it exerts its laxative effect better if taken stewed rather than with pastry.
