Another and most interesting phase of my subject is the relation of nut feeding to anaphylaxis. This newly coined word perhaps needs explanation for the benefit of my lay hearers. For many years it has been known that some persons were astonishingly sensitive to certain foods which indeed appeared to act as violent poisons. Oysters, shellfish, mutton, fish and other animal products, as well as a few vegetable products, especially honey, strawberries and buckwheat, were most likely to be the cause of these violent disturbances. More recently it has been found that cow's milk very often shows the same peculiarity. It is now known that this remarkable phenomenon is due to the fact that the body sometimes becomes sensitized to certain proteins which thereafter act as most violent poisons and may cause death. Sensitization to animal proteins is much the more frequent. In such cases nut products become a very precious resource. This is especially true with reference to cow's milk. Liquid nut preparations have saved the lives of hundreds of infants within the last twenty years. I have had the pleasure of meeting several fine looking young people who owed their lives to nut-feeding when other resources had failed. One case was particularly interesting. A telegram from a well-known Senator at Washington announced the fact that his infant daughter and only child was dying from mal-nutrition, as cow's milk and all the known infant foods had been found to disagree. I advised nut-feeding, and fortunately the prescription suited the case and the little one began to improve at once. When the physician in attendance learned that the child was eating nuts he vigorously protested, declaring that such a diet was preposterous and would certainly kill the infant, but the child flourished wonderfully on the liquid nut diet, eating almost nothing else for the first three years of her life, and today is a splendidly developed young woman, a brilliant witness to the food value of nuts. I have by no means exhausted the physiologic phases of my subject, but will now turn a moment in concluding my paper, to its economic aspects. The high price of nuts is constantly urged as an objection to their use as a staple. It is probable that a largely increased demand would lead to so great an increase in the supply that the cost of production, and hence the cost to the consumer, would be decreased. But even at the present prices the choicest varieties of nuts are cheaper than meats if equivalent food values are compared. This is clearly shown by the following table which indicates the amounts of various flesh foods which are equivalent to one pound of walnut meats.
