“40 per cent. Gluten Flour actually contains 40 per cent. of pure Gluten, making it a perfectly safe article of diet in all but the gravest cases of diabetes. From our Gluten Flour excellent bread, gems and puffs are made that perfectly satisfy the craving for bread with no harmful results.” This flour contains 33.63 per cent. of gluten, not 40 per cent.; it is not “a perfectly safe article of diet in all but the gravest cases of diabetes,” for if one reads the literature correctly, starch restriction is more necessary in mild than in severe cases of diabetes. Furthermore, the bread, gems and puffs made from such a flour do not “satisfy the craving for bread with no harmful results.” In the next paragraph of the letter, undue emphasis is laid on the “objectionable properties” of flesh foods, a statement only in accord with the tenets of extreme vegetarians. I also doubt very much whether the statement is true that “under a diet of our diabetic foods the thirst to which diabetics are so often subject is usually very much relieved.” In the next paragraph the assertion is made that “The diet indicated ... is in keeping with the ideas of the highest medical authorities.... Meat is entirely excluded from the dietary.” My reading of the literature does not show that the leading authorities take any such position. Later on reference is made to von Noorden’s claim as to the superiority of vegetable over animal proteins, which I have already discussed under “Pure Gluten Biscuit.” (Certain detached sentences of von Noorden might justify such a statement, but a reading of all he says on the subject leads to a very different conclusion.) CLAIMS MADE IN AN ADVERTISING BOOKLET The whole booklet is written from the standpoint of an extreme vegetarian, and therefore is often misleading in its conclusions. Page 5. “The researches of Ogata and others have shown that cane sugar is a less wholesome food than the natural sugars found in fruits and produced in the body by the digestion of starch, that is, fruit sugars and malt sugars.” In opposition to this I quote from von Noorden, their own authority, “Die Zuckerkrankheit und ihre Behandlung,” Berlin, 1910, page 270: “That levulose, milk sugar and inulin are more useful than the other carbohydrates is a common opinion, but the importance of their use in practice does not correspond with the theory. In light cases the form of carbohydrates makes little difference; in severe cases the advantage from using levulose, milk sugar, etc., is only slightly greater than from using bread and flour.... Only in certain cases does it appear to me that the special form of carbohydrates possesses any particular significance.”
