Desert Travelers, Take Note

A food that serves also as drink was reported last week by Harvard Medical School's Professor James L. Gamble. Glucose (grape sugar), said Professor Gamble, can profitably replace part of a man's water rations.

The body normally loses a good deal of water through the kidneys in washing away certain acids called ketones. Glucose prevents the formation of ketone acids; 100 grams of the sugar saves the body the loss of 140 grams of water. Moreover, Dr. Gamble found that men who were given glucose in place of part of their water allowance stayed more cheerful and active than those who got only water. Concluded Dr. Gamble: "Glucose contributes to courage."
