To quickly assess the difficulty of the text, read a short excerpt:
Another factor of much importance in the digestion of food, but one too often too lightly considered, is the mood or state of mind when the food is taken and while it remains in the alimentary canal. There is more than 234 FOOD moral philosophy in maintaining a cheerful and a tran- quil disposition during the daily meals and for a time thereafter; while there are numerous instances of most serious results occurring from the giving way to anger or other intense emotion at such times, the digesti...ve func- tions being either completely checked, or, what is fre- quently worse, so altered that their products are toxic in character. And is not a dyspeptic often so because of his pessimism, rather than a misanthrope because of his indigestion? Before proceeding further it will be well to consider briefly the physiology of digestion in so far as it concerns the chemical changes occurring in the food while it is in the digestive tract. These changes are brought about by the action of certain bodies secreted or elaborated by the digestive organs and glands, - which we have been in the habit of calling unorganized ferments, but which would, perhaps, better be known hereafter as enzymes.
