Understanding the Word of Wisdom: The LDS Health Code

An in-depth explanation of the substances to avoid and the foods to eat,
lists of risks and benefits, links to helpful websites, and answers to the most common questions about the Word of Wisdom.

What is the "Word of Wisdom"

The “Word of Wisdom” is a law of health revealed by the Lord for our physical and spiritual benefit. In short terms, it is a health code for the members of The Church of Jesus Christ of Latter-day Saints which we must abide by in order to go to the sacred temple and to have a healthy living. On February 27, 1833, the Lord revealed which foods should we eat and which substances must be avoided. He also promised the gift of health, protection, knowledge, and wisdom to His children that obeyed the Word of Wisdom.

The Word of Wisdom prevents the members of The Church of Jesus Christ of Latter-day Saints from consuming alcohol, tobacco, tea and coffee, illegal drugs, and harmful substances. It also teaches us to eat healthy foods such as fruits, vegetables, grains, and to eat meat sparingly.

In the Doctrine and Covenants section 89, the Lord revealed that the following substances are harmful and shouldn’t be consumed:

  • Alcoholic drinks (see Doctrine and Covenants 89:5–7).
  • Tobacco (see Doctrine and Covenants 89:8).
  • Tea and coffee (see Doctrine and Covenants 89:9; latter-day prophets have taught that the term “hot drinks,” as written in this verse, refers to tea and coffee).

And if we intentionally take anything harmful into our bodies, we are not living in harmony with the Word of Wisdom. Illegal drugs and abuse of prescription drugs can destroy us — physically and mentally.

In the Word of Wisdom, the Lord also declared that the foods that are good for us are:

  • Vegetables and fruits, which should be used “with prudence and thanksgiving” (see Doctrine and Covenants 89:10–11).
  • The flesh “of beasts and of the fowls of the air,” which is “to be used sparingly” (see Doctrine and Covenants 89:12–13).
  • Grains such as wheat, rice, and oats, which are “the staff of life” (see Doctrine and Covenants 89:14–17).

Okay, now that we already have the complete list above, I think it’s better if we discuss them one by one to make them clearer. Let’s start with the harmful substances that we shouldn’t consume or use: Alcoholic Drinks, Tobacco, Tea and Coffee, and other drugs. And after the Dos and Don’ts, we will proceed with the blessings of the Word of Wisdom.

“No” and “Never”

Alcoholic Drinks

If you are raised by a family that obeys the Word of Wisdom, ignoring alcoholic drinks throughout your life is a habit and lifestyle. But if you are still new in the Latter-day Saints faith and have been a moderate to heavy drinker, avoiding alcohol is a real nightmare.

But if you think of it thoroughly, you know it for yourself that alcohol intake is never a good idea right from the start — right from the moment you first tried alcohol. Let’s face the truth that we are in the midst of an alcohol epidemic. Since the early 1990s, social drinking has increased dramatically together with a similar increase in alcohol use disorders and drinking problems. If we look at the numbers, the alcohol-related death rate increased by 85% from 2007 to 2017. Don’t you think this is disturbing?

The effects of drinking alcohol will begin immediately once you take your first sip. Although one glass a day may not cause you dreadful effects, overcoming addiction will be your main concern. Once you find yourself having a hard time stopping after one glass, or if the habit grows, the cumulative effects can add up.

If you still have the thirst and I haven’t successfully pointed out the bad effects of alcohol, let me enumerate all the risks you will possibly face:

  • Behavior changes
  • Birth defects
  • Blackouts
  • Cancer
  • Alcohol Dependency
  • Diabetes complications
  • Fatigue
  • Frequent diarrhea
  • Hallucinations
  • Heart damage
  • Infertility
  • Liver damage
  • Lung infections
  • Malnutrition
  • Muscle cramps
  • Numbness
  • Pancreatitis
  • Sexual dysfunction
  • Shrinking brain
  • Slurred speech
  • Stomach distress
  • Thinning bones

For a detailed explanation of each of the above, check out healthline.com’s “The Effects of Alcohol on Your Body”. And since we’re talking about numbers, alcohol kills about 3 million people every year — which is about 5.3% of the total number of human deaths. But if people around the world have been living the Word of Wisdom, there would be no alcohol-related deaths.


You know that everyone is aware of the side-effects — no, the bad-effects — of tobacco. You have been taught not to try smoking since you were a kid, right? I won’t ask the “Why?” question because you certainly know that the use of tobacco has never been good.

In the Word of Wisdom, we are taught that we must not let tobacco enter our bodies. The reason is pretty simple — tobacco contains a highly addictive chemical compound called “nicotine” which makes people who smoke to continue to smoke. Nicotine is the culprit why smokers have a hard time to quit smoking. 

But nicotine isn’t the only villain in smoking. Cigarettes, cigars, e-cigarettes, vape, hookah, pipe, or any other similar products are made with other harmful chemical substances. These substances, together with nicotine, damage the human body. If we’ll go with numbers, tobacco kills more than 8 million people each year — more than  7 million smokers and about 1.2 million secondhand smokers.

“Wait, what? Secondhand?” Yes, you saw it right. Secondhand smoke is the smoke coming from the burning end of any tobacco product, or the smoke exhaled by the person who is smoking. So if you’re a smoker and you cannot stop smoking, think about the people around you.

The Word of Wisdom taught us not to use tobacco in order to prevent diseases such as:

  • Lung damage
  • Heart disease
  • Fertility problems
  • Risk of pregnancy complications
  • Risk of type 2 diabetes
  • Weakened immune system
  • Vision problems
  • Poor oral hygiene
  • Unhealthy skin and hair
  • Risk of other cancers

Tea and Coffee

The Word of Wisdom taught us that we should avoid “hot drinks” — tea and coffee. Our friends outside the church are definitely wondering why tea and coffee aren’t allowed. That’s why we are here to discuss more why drinking tea and coffee are against the Word of Wisdom.

We will start with the drug they contain. Both tea and coffee have  “caffeine” which is the world’s most widely consumed psychoactive drug — a chemical substance that changes the brain function resulting in alterations in mood, behavior, perception, consciousness, or cognition. Once consumed, caffeine’s effects will immediately start over.

In the medical field, there are findings that caffeine is used to reduce the risk of heart disease and type 2 diabetes, but still depends on the person taking it. People have been drinking tea or coffee alongside with pain relievers to treat migraine headaches, tension headaches, and even minor headaches.

However, this doesn’t mean that caffeine is good for our bodies. There are risks when you drink tea and coffee. First and foremost, you know that caffeine is addictive — after you drink a cup, you will crave for another cup, then another, until you find yourself having a hard time to quit. Believe me, people are having a hard time quitting tea and coffee, just like alcohol and tobacco.

For the record, 80% of the world’s population and 90% of Americans consume caffeine in every way. But even if it’s the most popular drug, it doesn’t mean that we also need to take it. Remember what President Russell M. Nelson said?

“Even if everyone is doing it, wrong is never right.”

Aside from addiction, there are other unpleasant side effects of caffeine which are very bad for our health:

  • Caffeine toxicity resulting in headache, nausea, vomiting, jitteriness, and irritability
  • Caffeine is known for its negative effects on sleep and anxiety
  • Caffeine overdose resulting in death
  • Abdominal pain
  • Seizures
  • Increased blood acid levels
  • Irregular or fast heartbeat
  • Reduced blood flow to the heart
  • Increased risk of heart attacks among young adults
  • Caffeine could reduce fertility in women

Another significant thing why we should avoid tea and coffee is because the Word of Wisdom teaches us to treat the human body as a temple. Every human body has its own capacity to do things. So if you are tired, that means your body needs some time to rest.

However, people drink tea and coffee to push their bodies to do more things which their bodies cannot handle. For example, a worker who has an 8-hour shift drank coffee to work for another 4 hours, a student drank tea to study overnight in preparation for the next-day exams, and you who are actually sleepy but need to stay awake for internet browsing. All of these examples are against the Word of Wisdom. Please respect the capacity of your body to do the work.

“Yes” and “Always”

And now that we’re done with the harmful substances to avoid, we will now talk about the foods that are good for our health. Remember, following the Word of Wisdom means following “ALL” of them. Eating the YES foods is as important as avoiding the NO substances.

Vegetables and Fruits

…which should be used “with prudence and thanksgiving”. I think you already know how healthy vegetables and fruits are, right? Your parents, your grandparents, your teacher, your doctor, or even your favorite childhood cartoon show already insisted you to eat vegetables and fruits as much as you could.

The flesh “of beasts and of the fowls of the air”

…which is “to be used sparingly”. We’re talking about meat, obviously. But we should eat just enough meat, not too much. We just need to complete our required daily amount of protein, vitamins, and minerals. Some of the bad effects of too much meat are dehydration, muscle cramps, body odor, constipation, headache, increased risk of vision loss, weaker bones, and fatigue. You can read the full details on bustle.com’s “9 Surprising Possible Effects Of Eating Too Much Meat”.


…such as wheat, rice, and oats, which are “the staff of life”. We need fiber in order to maintain a healthy weight, prevent constipation, lower the risk of diabetes, heart disease, and some types of cancer. It also lowers the cholesterol level, normalizes bowel movements and helps maintain bowel health, helps control blood sugar levels, and helps you live longer. And grains, such as wheat, rice, and oats, are high in fiber. For more details, read healthline.com’sWhy Is Fiber Good for You? The Crunchy Truth”.

What Does God Offer to Those Who Keep the Word of Wisdom?

If we obey the Word of Wisdom, the Lord promised that:

  • “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” (Doctrine and Covenants 89:18–21).

Frequently Asked Questions

1. What tea is against the Word of Wisdom?

All kinds of tea. Whether it’s green tea, white tea, black tea, herbal tea, or the all-around iced tea, all of them are made with tea leaves. So it is highly advisable to always check the ingredients of the drink before drinking them.

2. What coffee is against the Word of Wisdom?

All kinds of coffee. So if you’re in a coffee shop, it is difficult to choose what beverage to buy. Even decaf coffee has a small amount of caffeine! So if you’re in a coffee shop, always ask if there’s a coffee on your drink. (or never buy anything).

The church clarifies that drinks with names that have ‘cafe’ or ‘caffe,’ ‘mocha,’ ‘latte,’ ‘espresso’ or end with ‘-ccino’ typically contain coffee and are in violation of the Word of Wisdom.

The Word of Wisdom isn’t just a list of the forbidden things. It is a gift from God for us — His children — to live happier, healthier, and longer. The Word of Wisdom is not just a law, but it’s a commandment of God for us to become stronger and to help us treat our bodies like temples.

For the members of The Church of Jesus Christ of Latter-day Saints, living the Word of Wisdom is not difficult. In fact, we enjoy obeying it! However, for some friends outside the faith, or for newly-converted latter-day saints, living the Word of Wisdom is a big challenge.

Self-discipline, together with the strength from the Lord, help from family members and friends, and guidance from the church leaders, living the Word of Wisdom is as easy as ABC.
