It is also asserted that saliva does not dissolve some things (proteid substances) nor chemically affect them as visibly as it does starch and acid, but, even if this be true, it is no less essential that the juices provided in the mouth should have an opportunity, through mastication, or, movement about in the mouth, to do what they are able to do in assisting digestion. Experiment shows that if all foods are submitted to the examination and action of these juices until involuntary swallowing takes place, the results in aiding subsequent digestion are important in promoting healthy nutrition. Separation, neutralisation, alkalination, saccharidation, of the proteid and carbohydrate elements of common foods and perhaps a partial emulsification of fats are all possible in the mouth and are more easily and quickly done there than inside the body. Much care in Mouth-Treatment is an assurance of economy and safety in Alimentation. OBJECTIONS CONSIDERED One of the objections usually provoked by the suggestion that all tasteless residue remaining in the mouth after the taste or nutriment has been dissolved out of it should be removed is generally expressed in this wise, "How is it possible to remove refuse from the mouth while eating without appearing disgusting to others at table? You have to swallow things to get rid of them." This is merely a bugbear prejudice. It has no good reason. Do you not remove cherry pits, grape skins, the shell of lobster, bone, etc., when you encounter them? Then why not remove the fibrous matter found in tough lean meat, the woody fibre of vegetables or anything rejected by instinctive desire to discard it after taste has been exhausted, and which is a protection provided by beneficent Nature? In well selected and well cooked food there is little found that the juices of the mouth in connection with the teeth cannot take care of and prepare so as to be acceptable to Nature's Food Filter. If fibre is found in the food it can be put upon the fork in the same manner that a cherry pit is usually handled and transferred to the plate without observation. Another fancied objection to thorough mastication is that it interferes with the sociability of a meal. This is also a senseless bugbear. It is true that one cannot converse freely with large morsels of food in the mouth. It is also true that it is nothing less than a _gluttonous_ custom to greedily take a big mouthful of food, and, if accosted with a question, to bolt it in order to answer. It will be found easy to carry on conversation without disagreeable interruption and yet follow Nature's demands in properly masticating food by taking small morsels into the mouth. It will be found also to add to the real pleasure of eating, and eventually will become a habit by choice. Another objection raised by those who are afflicted with the habit of gluttony is the lack of time permitted by their business occupation.
