The relation between disease and faulty diet was first brought to the attention of scientists about the year 1880, by the experience of the Japanese navy. The prominent place of rice in the diet of those who suffered of beriberi, led to a belief that it was a causa- tive factor in the disease. In 1897, Eijkman took up the study of nutrition, demonstrating by experiment the fact that when pigeons were fed exclusively upon polished rice, they began to suffer of a nervous disorder, staggered, lost their power to stand up, or even to swallow food, and finally died. In other words, the pigeons developed a state of polyneuritis (inflammation of many nerves — Borland), which is analogous to beriberi in man. He found, more- over, that when the pigeons were fed on the entire kernel, the disease did not develop. In 1911, Dr. Casimir Funk took up the study of beriberi, and made an effort to isolate this singular yet unidentified substance contained in rice polishings, and also to determine what other foods contain it, and what influence it has on the health. He called this mysterious but absolutely indispensable substance "vitamine." The results observed among his birds when they were restricted to 16 milled rice and water were identical with those reported by Eijk- man. He found that when the coatings that had been removed from the rice were soaked in water, and a little of this fluid was passed through a tube into each sick bird's crop, or, if the birds had not reached the stage where they could not swallow, a portion of the rice polishings was fed to them, in a few hours they made rapid recovery, and before the day was over they were apparently as well as ever.1 It seemed like a veritable miracle. Evidently the Creator has placed in the covering of the rice something that is absolutely essential to life, and that the rest of the grain can- not supply. Funk demonstrated, furthermore, that when fowls were fed on steel roller process white flour, in three or four weeks they were afflicted just as when they were fed on polished rice. That is, he discovered that the vitamines are in the outer layers in wheat, just as they are in rice. These experiments clearly proved that there is required in the diet something more than protein, carbohydrate, fat, and mineral salts. In 1914, W. Richard Ohler, M. D.,2 carried out a number of experiments with chickens, in order to furnish experimental proof for the contention that a more or less exclusive diet of white bread was the chief cause of beriberi in Newfoundland. Fourteen chickens fed on white flour bread, with or without yeast, died within twenty-eight to forty days. Before death, the birds ex- hibited symptoms of polyneuritis, and histological examination of the peripheral nerves revealed considerable degeneration. Five chickens fed on whole wheat bread, and two on whole wheat, lived in perfect health for seventy-five days, when the experiment was discontinued. 1 These experiments were recently duplicated in the chemistry laboratory of the Col- lege of Medical Evangelists, by Dr. E. H. Risley, teacher of chemistry, with similar results, thus verifying the fact.
