The restlessness, craving for novelty, and love of excitement, so characteristic of the Anglo-Saxon, and to a less extent of some other European races, has its correspondence in the food of these races. Highly-seasoned and nitrogenous foods act as a stimulant and favour spasmodic, and for a time perhaps, great intellectual and physical exertion, with a succeeding period of exhaustion. Simpler food favours long, sustained, uniform muscular strength, clearness of intellect, and contentment. Let no one misunderstand us; we do not assert that all who live on simple food have either clear intellects or are contented, because there are other factors besides food, but that such qualities are more easily retained or obtained under that condition. It is well known that the over-fed and badly fed are the most irritable and discontented Those living on a stimulating dietary consisting largely of flesh have their chief successes in feats of short duration. Simple and abstemious living individuals or races excel in laborious work requiring endurance over long periods, such as long walking, cycling, and other athletic feats and long military campaigns. The digestive and assimilative organs need the food constituents of which we have written, in proper proportion and quantity, and in a fairly digestible condition. Within these very wide and comprehensive limits, the organs can be trained. Very much of the great difference in food is due to the non-essential flavouring and stimulating part, rather than to that part which is essential and nourishing. What is the best, interests but few; whilst what is at present the pleasantest, influences the many. The ego, the superphysical conscious and reasoning entity should rule its material body, its temporary vehicle. The body, being the servant of the ego, just as a horse, dog, or other of the lower animals recognises its master, becomes a docile subject. The body can be led into good habits nearly as easily as into bad ones; often more easily, as bad habits are sometimes painfully acquired. The body being once habituated to certain movements, conditions, foods or drinks, within reasonable limits, derives pleasure therefrom and resists change. It is only when the food, etc., transgresses certain elementary principles, that the result is more or less painful. We may on scientific principles condemn flesh-foods, stimulants and elaborately prepared foods; but after ruling all this out, there is still left a very great variety of foods and methods of preparing them: hereon each individual must form his own opinion. Of the foods thus left, the same kind is not equally suitable to everyone, nor even to the same person at different periods.
