Scholarship and the scientific method are seen as the gold standard of truth in out modern society. However, John Ioannidis, professor of medicine at Stanford University, who specializes in the study of scientific studies, has shown that many studies have very poor study design and execution. Dietary studies tend to be the worst offenders. The consequence of poor study methodology is erroneous conclusions. According to Dr. Ioannidis. conclusions made from the endless terrible studies on coffee, chocolate and red wine," should be avoided.
This criticism from John Ioannidis of dietary studies should be of no surprise to Latter-day Saints. LDS appreciate and respect sound scholarship and the scientific method, but we see revelation through God’s ordained priesthood authority as the highest standard of truth. God has revealed in the Word of Wisdom (D&C 89) to the prophet Joseph Smith that “hot drink” and “strong drinks” together with tobacco are “not good for the belly”.
However, these natural substances are given unto man and have their uses. Just as the revelation reveals, alcohol is useful for “the washing of the body” as both a clensing solvent and disinfectant. Tobacco, prepared as a poultice, is useful to speed the healing of bruises. Using alcohol as a disinfectant and tobacco prepared as a poultice for bruises is perfect medicine.
