Remember this! Salt, sugar, some sauces and spices which are used to make food palatable may be in themselves nutritious, but do not let them mislead you. The tendency is to relish them and think that they represent the food they disguise, which, however, is often only an excuse for them, and has very little nutrition itself. In this case a morsel of food is taken into the mouth, the sauce or spice which it carries meets immediate response from Taste and disappears, whereupon the indigestible food morsel is swallowed in indigestible condition so as to admit another sauce-laden supply.

The most nutritious food does not require sauces. It may seem dry and tasteless to the first impression, but, as the juices of the mouth get possession of it, warm it up, solve its life-giving qualities out of it and coax it into usefulness, the delight of a new-found delicacy will greet the discoverer.

It may be difficult, at first, to avoid swallowing food before it is thoroughly separated, the nutriment dissolved and the dirt rejected, but after a little practice there will be no difficulty. On the contrary, there will be an involuntary habit of retention established that will be as tenacious of a morsel of food till that last and sweetest taste has been found, as a dog is tenacious of a savory bone.

Did it ever occur to gum chewers that the gum is simply an exciter of saliva, and that the sweet taste is the nutritious dextrin in the saliva and has nothing to do with the gum? In the ordinary "watering of the mouth" the same sweet taste is experienced.

Another important fact in this connection, and which belongs in the list of "directions" because it is a leader, is, that perfect nutrition is a source of ample saliva, the effect thereby reproducing the cause in friendly reciprocity.

It will be found that, when normal conditions have been attained through attention to the inspection, selection and rejection of Taste, when the tongue has lost its malarial yellow scum and when Hunger is represented by healthful Appetite and has dismissed bilious and insatiable Craving from its service, there will at all times be a delicately sweet taste in the mouth which will prevent craving for anything else. For instance, a person in possession of normal taste conditions may pass a confectionery shop or a fruit stand without temptation to eat of their wares, for they would spoil the taste already in possession of the mouth.

The expert wine tasters in Rhineland, where the full flavour of the luscious fruit is retained in the wine as Nature put it there, never drink wine. They breathe it into the mouth and atomise it on the tongue with utmost relish. To them the swallowing of the precious juice without dissipation by taste is an unpardonable sacrilege. The Bavarians also, whose beer is the best in the world, practically do not drink beer as Americans are accustomed to seeing it drunk. They sit over a stein of beer for an hour, reading or chatting with friends. The epicurean drinkers of what has been termed eau de vie in France sit and sip a "pony" of their beloved Cognac while they enjoy a view of pastoral loveliness or a throng of passers-by in a boulevard of Paris. None of these people drink anything but water and hence are not drunkards; and, at the same time, they have full enjoyment of Nature's most stimulating and delicious compounds in a form preserved by Nature for the use of man.

The taste of these students of nutrition becomes so discriminating that they can distinguish a wine or a beer or a cognac, as they would distinguish between intimate friends and strangers. The year, the vineyard, the state of the weather, or any accident that may have surrounded the development of the fruit are as distinguishable to these epicures in the essential juices as are the marks on men which indicate prosperity, happiness or any stamp of environment whatever.

An epicurean cannot be a glutton. There may be gluttons who are less gluttonous than other gluttons, but epicureanism is like politeness and cleanliness, and is the certain mark of gentility.

A physiological chemist, a friend of the author, who is responsible for the suggestion that the function of saliva in turning the starches of our food into nutritious glucose may never have been fully given a chance to act, thus accounts for the last delicate sweet taste which is attained by complete mastication. It is then a perfect solution, and hence the delicacy of the taste.
