Article #1: The Question Of Proteins By Arnold DeVries
The following is an excerpt from a book by Arnold DeVries called Fountain of Youth.
The building blocks of protein consist of 23 amino acids. Eight of these have been proven to be essential for the support of life and growth. A few others are “convenient” in the sense that animals thrive better if they get them. Proteins which contain all of the essential amino acids as well as the convenient ones, are called complete or first class. A food which contains complete protein will support life and growth if used as the sole source of protein in the diet. The foods which contain incomplete protein will not in themselves support life and growth.
It is often claimed that the difficulty of obtaining complete proteins on a fruitarian diet makes such a diet dangerous except when in the hands of an expert. But this is really not so. A child living upon the fruitarian diet could hardly keep from getting sufficient complete protein if he simply used the plant foods according to his own instinctive desires. After all, there is an abundance of plant foods which supply us with complete proteins of the highest biological value. The researches of Cajori, Van Slyke and Osborn have known conclusively that the protein of most nuts is of the very finest type and contains all of the essential and convenient amino acids. Among the nuts possessing complete proteins are butternuts, pecans, filberts, Brazil nuts, English walnuts, black walnuts, almonds, pine nuts, chestnuts and coconuts.
In addition to being complete, the protein of most nuts is of high biological quality. Investigations at Yale University and the research work of Dr. Hoobler of the Detroit Women’s Hospital and Infant’s Home both demonstrate the superiority of nut protein. The methods of research used by Dr. Hoobler provided a most delicate biological test of the protein of food, and it showed that the protein of nuts not only provides greater nutritive efficiency than that of meat, milk and eggs but that it is also more effective than a combination of the animal proteins.
Coconut globulin is perhaps the best of the nut proteins. Johns, Finks and Pacel of the Protein Investigation Laboratory of the U.S. Department of Agriculture found that this protein produced supernormal growth in young rats when used as the sole protein in the diet. In other words the rats grew more rapidly than when given cheese, meat, eggs, milk or any other high-protein food. McCandish and Weaver have also found that the protein of coconuts is superior to that of other foods and claim that coconut meal is of greater value than soybean meal. As the soybean is equal in biological value to any of the animal proteins, this would mean that the coconut protein is in a class by itself and is perhaps the finest protein known.
No fruitarian need have any worries over his protein supplies. Any well-balanced selection of plant foods should meet the body’s protein needs very well; in fact, it will meet them far better than the omnivorous diet, for it supplies the protein in just the right amounts.
All available evidence indicates that a low-protein diet composed of plant foods is most conducive to the best health. In the 19th century two great German scientists, Justus Freiherr von Liebig and Karl von Voit, carried out experiments to determine how much protein the body requires each day. Liebig assumed that, because muscle is composed largely of protein, we should use a diet which is very rich in this dietary factor. Later Voit carried out experiments with dogs, the result of which led him to believe that the daily human requirement is 118 grams.
It is now known that the conclusions of Liebig and Voit are not accurate. Muscles can be built from plant foods, which are relatively low in protein content better than from animal flesh. And the experiments with dogs carried out by Voit can hardly be applied to human beings, for the protein requirements of dogs and other carnivorous animals differ from those of the frugivorous animals.
The most accurate present day estimates of the body’s daily protein requirement vary from about 22 to 30 grams. These estimates are based upon experiments with humans. Prof. Henry Sherman of Columbia University places the daily requirement at 30 to 50 grams, but it is probable that the other estimates, which include those of the Swedish scientist Ragner Berg, are more nearly correct. However, even 30 to 50 grams of protein is not much. It could easily be supplied by a diet of plant foods.
Dr. Mikkel Hindhede, of Denmark, made the first mass application of a diet very low in its protein content to an entire nation. During World War I this doctor was made Food Administrator of Denmark. In an effort to prevent food shortages, he greatly lowered the production of livestock and fed the plant foods to the human population rather than to the animals. As an average of only 10 percent of the value of plant foods is recovered in the milk, eggs and meat of the animals, it is obvious that this involved a great saving from the standpoint of nutrition. But Hindhede eventually discovered that the diminished use of animal foods meant far more than that. Within one year’s time the death rate had decreased 40 percent. In addition, the Danish people experienced less disease. When thousands of people throughout Europe suffered influenza, Denmark was not affected. The other nations, using their high-protein diets consisting largely of animal foods, suffered greatly and their people died by the thousands.
Nuts are rich in protein, but they are not used to such an extent in the fruitarian diet that the body receives an excess of this material. The normal desires of the fruitarian call for a wide variety of plant foods with no particular dependence upon nuts. Fruits are the chief foods used and the desire for nuts is in accordance with the body’s need for protein. Meat, eggs, milk and cheese are all unneeded high-protein foods. Their excessive protein acts as a burden to the body and favors the development of disease.
