The Malays Mix Native Vegetables With Them And Thus Make A Kind Of Stew.

The rice traded in Borneo is of the ordinary polished variety, almost exclusively from Rangoon, and it is generally supposed that the polishing of the rice is the cause of this illness.

The Dutch army in the East seems to have obtained good results by providing the so-called silver-fleeced rice to the soldiers. However, I was told that, in some localities at least, the order had to be rescinded, because the soldiers objected so strongly to that kind of rice. Later, on this same river, I personally experienced a swelling of the ankles, with an acceleration of the heart action, which, on my return to Java, was pronounced by a medical authority to be beri-beri. Without taking any medicine, but simply by the changed habits of life, with a variety of good food, the symptoms soon disappeared.

It is undoubtedly true that the use of polished rice is a cause of beri-beri, because the Dayaks, with their primitive methods of husking, never suffer from this disease, although rice is their staple food. Only on occasions when members of these tribes take part in expeditions to New Guinea, or are confined in prisons, and eat the rice offered of civilization, are they afflicted with this malady. In my own case I am inclined to think that my indisposition at the commencement of my travels in Borneo was largely due to the use of oatmeal from which the husks had been removed. Rolled oats is the proper food.

Modern research has established beyond doubt, that the outer layers of grains contain mineral salts and vitamines that are indispensable to human life. Facts prove that man, if confined to an exclusive diet of white bread, ultimately dies from malnutrition. Cereals which have been "refined" of their husks present a highly starchy food, and unless they are properly balanced by base-forming substances, trouble is sure to follow. Scurvy, beri-beri, and acidosis have been fatal to many expeditions, though these diseases no doubt can be avoided by a judicious selection of provisions that insure acid and base forming nutrition in the right proportion. [*]

[Footnote *: For an illuminating example of poorly balanced food, see Physical Culture Magazine, New York, for August, 1918, in which Mr. Alfred W. McCann describes the disaster to the Madeira-Mamore Railway Company in Brazil, when "four thousand men were literally starved to death on a white bread diet." In the July number may be found the same food expert's interesting manner of curing the crew of the German raider Kronprinz Wilhelm, which in April, 1915, put in at Newport News, in Virginia, with over a hundred men seriously stricken with acidosis. The crew had enjoyed an abundance of food from the ships they had raided and destroyed, but a mysterious disease, pronounced to be beri-beri, was crippling the crew. As the patients failed to respond to the usual treatment, the ship's chief surgeon consented to try the alkaline treatment which Mr. McCann suggested to him. The patients rapidly recovered on a diet consisting of fresh vegetable soup, potato-skin liquor, wheat bran, whole-wheat bread, egg yolks, whole milk, orange juice, and apples. No drugs were administered.

It may be added that Dr. Alfred Berg (in the same magazine, September, 1919) recounts the cure of an absolutely hopeless case of stomach trouble by the vegetable juice prepared according to McCann's formula. He has found the results gained by the use of this soup in diet "so remarkable as to be almost unbelievable."

The formula in question, as taken from McCann's article, is: "Boil cabbage, carrots, parsnips, spinich, onions, turnips together for two hours. Drain off liquor. Discard residue. Feed liquor as soup in generous quantities with unbuttered whole-wheat bread."]

As a precautionary measure during my further travels in Borneo I adopted the green peas of the Orient in my daily diet, and when properly cooked they suit my taste very well. Every day my native cook made a pot of katjang idju, to which I added as a flavour Liebig's extract, and when procurable different kinds of fresh vegetables such as the natives use. Almost any kind of preserved vegetables or meat, especially sausages, is compatible with this stew, which is capable of infinite variations. For a year and a half I used it every day, usually twice a day, without becoming tired of it, and this regimen undoubtedly was the reason why the symptoms of acidosis never reappeared.

I may add that besides this dish my main food was milk and biscuits, especially those made of whole wheat. In the tropics no milk will keep beyond a certain time limit unless it is sweetened, which renders it less wholesome. I found Nestle & Company's evaporated milk serviceable, but their sterilised natural milk is really excellent, though it is expensive on an expedition which at times has to depend on carriers, and in mountainous regions like New Guinea it would be impracticable to carry it. Under these conditions one is content to have the evaporated or the sweetened brand. Sterilised milk, although perhaps a luxury, is a permissible one when travelling by boat, but the fact that it remains sound only a limited time should be borne in mind. However, it helped me to resist the adverse conditions of travel in the equatorial regions, and to return to civilisation in prime physical condition. When I had opportunity I ate the rice of the Dayaks, which is not so well sifted of its husks, and is by far more palatable than the ordinary polished rice. I found the best biscuits to be Huntley and Palmer's College Brown, unsweetened.

As regards one's native companions, the Dayaks or Malays are quite satisfied as long as they get their full rations of rice and dried fish. This is the food they have always been accustomed to and their demands do not go further, although cocoanut-oil for frying the fish adds to their contentment.
