"All grain is ordained for the use of man and of beasts, to be the staff of life, not only for man but for the beasts of the field, and the fowls of heaven, and all wild animals that run or creep on the earth; "And these hath God made for the use of man only in times of famine and excess of hunger. "All grain is good for the food of man, as also the fruit of the vine, that which yieldeth fruit, whether in the ground or above the ground. "Nevertheless, wheat for man, and corn for the ox, and oats for the horse, and rye for the fowls and for swine, and for all beasts of the field, and barley for all useful animals, and for mild drinks, as also other grain. "And all saints who remember to keep and do these sayings, walking in obedience to the commandments, shall receive health in their navel, and marrow to their bones; "And shall find wisdom and great treasures of knowledge, even hidden treasures; "And shall run and not be weary, and shall walk and not faint. "And I, the Lord, give unto them a promise, that the destroying angel shall pass by them, as the children of Israel, and not slay them. Amen." (D&C 89.) Hot drinks, against which the people are specifically warned, are understood to include tea and coffee, and the counsel against their use was preached and published long before chemists and physiologists had recognized the deleterious effect of thein and caffein, which are poisonous alkaloids contained in the beverages named. The inhibition, however, applies in another sense to all liquids at high temperatures. To this point special interest attaches in view of recent demonstrations in science. Dr. Wm. J. Mayo, a surgeon of prominence, declared in an address delivered in San Francisco, June, 1915, that hot drinks are among the dominant causes of gastric ulcers and cancer. The Word of Wisdom is generally but not universally observed in its entirety by the Latter-day Saints; and it is pertinent to inquire as to the results revealed by the vital statistics of the people. The Presiding Bishopric of the Church report that, for the six year period ending with 1916, deaths among Latter-day Saints in the organized Stakes, due to cancers and malignant ulcers of the stomach, averaged 15.83 per 100,000 of population. For the United States registration area as a whole, during the six year period covered by the latest available report, which, however, is earlier than the sexennium of the latest Church statistics, the average mortality from stomach cancer is 28.3 per 100,000. Deaths from all cancerous afflictions among members of the Church during the last six years averaged 31.15 per 100,000, or only 2.85 more per 100,000 than the national rate of mortality from stomach cancer alone for the six years last reported.
