In the realm of religious practices and beliefs, the Mormon faith has long captivated the curiosity of outsiders. One question that often arises is the apparent contradiction between the Church of Jesus Christ of Latter-day Saints (LDS Church) allowance of diet cola beverages while forbidding the consumption of coffee. On the surface, this discrepancy may seem puzzling, but upon delving deeper into the intricacies of Mormon doctrine and history, a clearer understanding emerges. This blog post aims to explore the reasons behind the Mormon stance on diet coke and coffee, shedding light on the cultural, theological, and historical factors that have shaped these practices.

Why can Mormons have diet Coke but not coffee?

The Cultural Context: A Mormon Tapestry of Abstinence and Moderation

Within the Mormon community, abstinence from certain substances and practices is seen as an expression of devotion and commitment to God. The tradition of abstaining from alcohol, tobacco, and illicit drugs is deeply ingrained in Mormon culture. However, the question remains: why are some caffeinated beverages, like diet Coke, permissible while coffee is strictly prohibited?

In the complex tapestry of Mormon cultural norms, caffeine consumption has historically been viewed with caution, as it was believed to be associated with addictive and potentially harmful substances. This perception, combined with the historical and cultural connection between coffee and alcohol consumption, has contributed to the LDS Church’s stance on coffee. In contrast, diet coke, as a carbonated beverage without the negative connotations of alcohol or the direct association with coffee, is seen as a more acceptable choice within the realm of moderation.

Theological Foundations: Doctrinal Considerations and Spiritual Symbolism

Mormonism places a significant emphasis on the concept of the “Word of Wisdom,” a revelation received by church founder Joseph Smith in 1833, which outlines guidelines for healthy living. While the Word of Wisdom explicitly discourages the use of “hot drinks,” the exact definition of this term has evolved over time. Initially, it was interpreted to include tea and coffee due to their stimulating effects and addictive qualities. However, the specific mention of “hot drinks” has led to ongoing debates within the Mormon community regarding the inclusion or exclusion of other caffeinated beverages.

The LDS Church’s interpretation of the Word of Wisdom has evolved to emphasize principles of individual agency and personal revelation. Mormons are encouraged to make their own informed choices and seek guidance from God through personal revelation. Consequently, the church does not take a rigid stance on caffeine consumption as a whole but instead advises its members to use their judgment and follow their conscience. This approach allows for individual variation, explaining why some Mormons may choose to avoid coffee while consuming diet Coke in moderation.

Historical Development: The Legacy of Mormon Pioneers

To fully comprehend the Mormon perspective on diet Coke and coffee, it is crucial to examine the historical context in which these practices emerged. The 19th-century Mormon pioneers embarked on a perilous journey, facing numerous challenges while seeking a place to practice their faith freely. During this time, hot drinks like coffee were scarce and difficult to obtain on the frontier, while other caffeinated beverages like tea were commonly consumed. This scarcity and the associated cultural context contributed to the inclusion of coffee in the list of prohibited substances within the Word of Wisdom.

Over time, as the church expanded and encountered different cultural contexts, the focus of the Word of Wisdom shifted towards broader principles of health and well-being. Consequently, the interpretation of the prohibition on “hot drinks” became more flexible, allowing for personal discretion. This historical development highlights the adaptive nature of Mormon practices and their ability to evolve in response to changing circumstances.

Practical Considerations: The Role of Health and Social Dynamics

Beyond cultural, theological, and historical factors, practical considerations also play a role in the Mormon approach to diet Coke and coffee. The Mormon faith promotes health and wellness, and some studies have suggested potential health benefits associated with moderate consumption of caffeine. Diet Coke, with its reduced sugar content, is often viewed as a healthier alternative to regular sodas. This consideration, coupled with the absence of coffee’s stimulating effects and potential addiction, makes diet Coke a more acceptable choice within the Mormon community.

Furthermore, the social dynamics surrounding caffeinated beverages differ significantly from those surrounding coffee. Coffeehouses, for example, have historically served as gathering places for intellectuals and social activists, sometimes associated with political or countercultural movements. By avoiding coffee, Mormons may be consciously or unconsciously distancing themselves from these associations while still participating in contemporary social norms by consuming alternative beverages like diet coke.


The Mormon stance on diet coke and coffee arises from a complex interplay of cultural, theological, historical, and practical factors. While diet coke is considered permissible due to its lack of historical and cultural baggage associated with coffee, the LDS Church’s flexible interpretation of the Word of Wisdom allows for individual choice and personal revelation. Understanding the intricate layers of Mormon doctrine and history provides valuable insights into the unique practices of this vibrant religious community. By exploring the reasons behind their dietary guidelines, we gain a deeper appreciation for the diversity and richness of religious traditions in our world.
