C.T. writes.--I have read the article on sugar with considerable interest. I have noted nervous disorders, etc., manifest in cases of excessive consumption of manufactured sugar. I have been an abstainer from cane sugar (all commercial sugars, though _I do not know of any objection to milk, sugar_) for many years, regarding it as an unnatural excitant and stimulant as well as being inimical to digestion. As a physiologist I have taken immense interest in longevity, feeling that an active life past the age of ninety-five or a hundred, and upwards, carries with it, in evidence of right living, the force of demonstration, and more conclusively, in direct ratio to the advance of years. I firmly believe that all anomalies will ultimately admit of resolution. In this connection I could mention a number of strange and paradoxical cases for which, as yet, I have obtained no solution. I know of centenarians who began using "sugar" freely late in life. In one case, when past eighty, a new set of teeth (not odd "supernumeraries") appeared all round! How is it, again, that the natives of the West Indies, when living on sugar (in its crude state, I suppose) have excellent teeth and perfect health? Is not raw sugar better the less manufactured it is? On the other side, Captain Diamond, at 114, attributes his health in great measure to abstinence from sugar. Most of these queries are answered in the completed book[10] published this year. The point about "milk sugar" not being injurious he will find answered on page 72. [10] _The Truth about Sugar_, 1s. net. (C.W. Daniel, Ltd.) "Milk sugars" taken to excess with a mixed diet, or in the form of milk as a beverage, break down into lactic, butyric and other destructive acids under the influence of intestinal germs and thus do harm to the body. The natives of the West Indies (page 39) take the sugar cane in its natural state as a living vegetable food--a very different thing from the isolated and chemicalised sugar on our tables at home. Moreover, the chewing required helps digestion. This is very different to the drinking rapidly of sugared beverages, which do not receive this necessary mouth preparation. One is quite prepared to admit that paradoxical cases do occur where sugar seems to agree well even with octogenarians, but they are, in my opinion, the exceptions, and I am constantly coming across cases where the free consumption of table sugars has proved very harmful to both old and young.
