Word of Wisdom: The LDS Health Law and Why No Coffee

What the Word of Wisdom Prohibits

The Word of Wisdom is a revelation given to Joseph Smith on February 27, 1833, recorded in Doctrine and Covenants 89. It outlines principles of health for the church, prohibiting certain substances and encouraging the consumption of wholesome foods. The revelation begins by addressing the use of tobacco and "hot drinks," interpreted by church leaders as coffee and tea. It prohibits alcohol and encourages grains, fruits, vegetables, and the sparing use of meat.

The phrase "hot drinks" in the original revelation was interpreted by early church leaders, particularly Joseph Smith and Brigham Young, to mean coffee and tea. This interpretation has been consistently maintained. It does not prohibit other warm beverages—herbal teas are generally considered acceptable. The theological rationale is that coffee and tea are physical stimulants containing caffeine that cloud the mind and make one dependent, contrary to the virtues of clarity and self-mastery. Latter-day Saints are encouraged to pray about their choices and use the Spirit to guide their lives, which requires mental clarity.

What the Revelation Recommends

The Word of Wisdom also teaches principles of moderation. While it permits meat, it counsels "in times of winter, or of cold, or famine" (D&C 89:13), suggesting that excess consumption is not ideal. Fruits and vegetables are "good for man" (D&C 89:11). Grains are referred to as "the staff of life" (D&C 89:14). These teachings reflect principles of balanced nutrition that align with modern nutritional science.

When Did It Become a Commandment?

The original revelation was not given as a commandment but as "not by commandment or constraint" (D&C 89:2). However, the practice gradually became linked to worthiness. In 1902, church President Joseph F. Smith made adherence to the Word of Wisdom a requirement for temple attendance. Over decades, it became a standard expectation for all members. Today, members declare their observance of the Word of Wisdom during their annual temple recommend interview with local church leaders.

Health Research on Latter-day Saint Populations

The health benefits of following the Word of Wisdom are well documented in medical literature. The Adventist Health Study, which followed Seventh-day Adventists (who also prohibit alcohol and tobacco but not coffee and tea), found statistically lower rates of cancer, heart disease, and other chronic illnesses compared to the general population. LDS populations show similar health outcomes. Members do not claim the Word of Wisdom is magical, but rather that it reflects divine wisdom about what the human body needs to be healthy and strong.

Beyond the physical health benefits, members view the Word of Wisdom as a spiritual discipline. Keeping it is an act of faith—trusting that God knows what is good for us, even when the broader culture encourages different choices. It is a visible way of showing commitment to God and to the gospel. Members who observe it speak of greater mental clarity, better sleep, and increased spiritual sensitivity.

The promises attached to the Word of Wisdom are recorded in Doctrine and Covenants 89:18-21: "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." These promises motivate faithful members to observe the law.
