Because of such statements, some adherents believe that caffeine is officially prohibited under the Word of Wisdom. In the mid-1950s, the director of the food services for Brigham Young University, a college owned by the LDS Church, decided not to sell caffeine on campus. This changed in September 2017 when the director of BYU Dining Services announced that caffeinated beverages would be sold on campus. Wright said this was the result of a change in customer preferences. Official church publications have occasionally published articles by medical practitioners that warn of the health risks of consuming caffeine. However, in November 2010, the "Salt Lake Tribune" noted that in the 2010 church "Handbook", which sets out the official position of the church on health and social issues, no position on drinking Coca-Cola or caffeinated drinks is included. "The Salt Lake Tribune" concluded that the church "takes no official position on caffeine".
