The suggestions offered in the previous chapter concerning the necessity for the enjoyment of food, give one a fairly clear idea as to what he should eat. In other words, he should select those foods that he thoroughly enjoys, keeping in mind the necessity of using only those that are at least reasonably wholesome. If you have a large variety from which to select, this will be to your advantage, provided you do not include too many foods at one meal. It is a good plan to get your variety from meal to meal and from day to day, but without including too many dishes at any one meal. One of the most remarkable cases of longevity with which I have ever come in contact proved in a very pointed way the value of this suggestion. This was a woman who had lived to be over eighty years of age. During the last forty years of her life she was as agile, as clear- headed and as capable as a young woman in the heyday of her youth. I am satisfied that to a large extent the unusual vitality possessed by this woman was due to her habit of eating but one article of food two meals each day, although occasionally she would eat only one. Her meals were taken irregularly, because she would eat only when she was hungry. When she had a definite appetite it would nearly always indicate to her the particular food that she wanted. She would then prepare a meal of this food and thoroughly satisfy her appetite with it. Nothing else was eaten at that meal. This woman naturally went through some very severe trials before she adopted this diet-indeed, a terrible lesson of some sort seems necessary to compel one to follow a strict dietetic regimen. At the age of forty she was a physical wreck, having been for years tortured with rheumatism. Having vainly tried every other remedy, she finally became interested in diet, and through it finally overcame her difficulty. It might also be of interest in this connection to know that she never used salt, pepper, or condiments of any sort with her meals, and it would be well to emphasize that it is important to avoid the too free use of condiments and stimulating foods. We have used salt so long that our bodies seem adapted to it, and it is usually considered essential to the welfare of domestic stock; therefore it is a moot question as to whether it is advisable for human beings to avoid it altogether. Yet the excessive use of it to which we are prone is certainly harmful. How is this to be avoided? If we eat our food in a hand, I have found that the longer you are without it the more you long for it, until the craving becomes much more intense than is the hunger of a man who fasts (the symptoms are those of a disease rather than of being hungry). Among the uncivilized Eskimos the dislike of salt is so strong that a saltiness imperceptible to me would prevent them from eating at all. This fact was often useful to me, and when our Eskimo visitors threatened to eat us out of
