The Seventh-day Adventist (SDA) diet is a dietary approach promoted by members of the Seventh-day Adventist Church, emphasizing a holistic approach to health that integrates physical, mental, and spiritual well-being. This diet, rooted in the belief that the body is a temple of the Holy Spirit, encourages a lifestyle of wellness through a plant-based diet, exercise, temperance, and reliance on natural remedies like pure water, fresh air, and sunlight. The Seventh-day Adventist Church has angled in this direction and many experts have said that the Seventh Day Adventist food beliefs and diet approach are one of the healthiest diet options available. Those who follow this faith aim to follow an overall healthy lifestyle, which includes a good diet, exercise, pure water, adequate sunlight, temperance, fresh air, rest, and spirituality.
Core Principles of the Seventh-day Adventist Diet
The SDA diet is not just about what you eat, but how you live. It's a lifestyle that promotes balance, moderation, and wellness. Too much of anything, even something good, can be harmful to your health. The key principles include:
- Balance and Moderation: Emphasizing that too much of anything, even healthy foods, can be detrimental.
- Natural Remedies: Prioritizing pure water, fresh air, and sunlight as essential for health.
- Exercise: Recognizing physical activity as a means to clear the mind and maintain physical health.
- Avoidance of Harmful Substances: Abstaining from alcohol, tobacco, and mind-altering substances.
- Plant-Based Nutrition: Promoting a well-balanced vegetarian diet rich in legumes, whole grains, nuts, fruits, and vegetables, along with a source of vitamin B12.
- Biblical Dietary Laws: Adhering to the guidelines in Leviticus 11 and Deuteronomy 14 regarding "clean" and "unclean" foods.
Foods Commonly Consumed
Vegetables, fruits, whole grains, legumes, nuts, and seeds make up the crux of the diet. A good diet according to Seventh-Day Adventists involves eating a mainly plant-based diet, which incorporates, vegetables, fruits, whole grains, nuts and seeds, and legumes.
- Fruits and Vegetables: There is no limitation to the fruit and vegetable choice.
- Whole Grains: Whole grains have a high fiber content that reduces the risk of diabetes and heart disease. Examples include brown rice, barley, oatmeal, popcorn, whole-wheat bread, buckwheat, and millet.
- Nuts: Nuts contain healthy fats that are good for the heart. Eating nuts as part of a healthy diet can cut your risk of having a heart attack in half if you're in a high-risk group. They can lower your bad cholesterol (LDL), ease inflammation linked to heart disease, lower your odds of blood clots and help keep the lining in your arteries healthy.
- Legumes: This category includes beans, peas, chickpeas, and lentils. Eating 1 cup of legumes daily has been associated with losing weight, lower cholesterol, lower blood sugar, and lower blood pressure.
Dietary Restrictions: What to Avoid
The Seventh-day Adventist diet involves certain restrictions, primarily based on biblical guidelines and health considerations.
Unclean Meats
Adventists also understand that the health laws set in Leviticus and Deuteronomy still apply -that they were not ceremonial laws, but God laying out perimeters for the healthiest living and sanitation. For those who eat meat, they abstain from unclean meats as stated in Leviticus 11 and Deuteronomy 14. The distinction between clean and unclean meats referenced in the Bible is not merely ceremonial and an arbitrary regulation, but is based upon sanitary principles that lower the risk of diseases.

The Bible delineates specific categories of animals as "clean" and "unclean," influencing the dietary choices of Adventists who consume meat.
- Unclean Mammals: Mammals with divided hoof but do not chew cud (e.g., pig-pork in all its forms). Mammals that chew cud but hooves are not divided (e.g., camels, rabbits, rock badgers, etc.)
- Unclean Marine Animals: Marine animals without fins and scales (These include all shellfish, all sea mammals, all soft body water animals, caviar, etc.).
- Unclean Birds: Specific unclean birds especially birds of prey and scavengers (e.g., eagles, vultures, falcons, crows, owls, hawks).
- Unclean Insects: All other insects without jointed jumping legs.
Other Restrictions
In addition to abstaining from unclean meats, the Seventh-day Adventist diet typically restricts or discourages the consumption of:
- Alcohol: Seventh Day Adventists, in keeping with their belief that the body is the temple of the holy ghost, strongly discourage and abstain from the consumption of any alcoholic beverages.
- Caffeinated Beverages: They abstain from tobacco, tea, and any other caffeinated beverages. Like coffee, their caffeine content make them a stimulant, and as a result, they both unnaturally excite the nerves leading to objectionable long-term effects.
- Tobacco and Mind-Altering Substances: The SDA church also strongly discourages the use of tobacco and any other mind-altering substances.
- Animal food with the blood: Animal food was not to be consumed with the blood.
- Animals that died from natural death or by another animal: Animals that died from natural death or by another animal were not to be consumed.
- Animals eaten with their fat: Animals were not to be eaten with their fat.
- Overeating: As it pertains to overeating, scientific studies link overeating with weight gain which can eventually lead to obesity, the imbalance of hormones that stimulate or suppress appetite, the malfunction of digestive organs, and both mental and physical lethargy. As a result, eating to feel full is discouraged.
- Dairy products: Because their diet promotes a less rich diet with limited fat, sugar and salt, dairy products are not considered the healthiest options even for a vegetarian diet. Milk and other dairy products are the primary sources of artery-clogging saturated fat in the American diet.
Scientific Basis and Health Implications
The Seventh-day Adventist church promotes a wholesome plant-based diet which includes fruits, vegetables, whole grains, nuts, seeds and legumes. The understanding that the original diet given to man is the diet that the human body functions best on is now fully validated by verifiable scientific data. God knew that a plant-based diet would impart a strength, power of endurance, and vigor of intellect that animal flesh could not afford. For these reasons, God gave the health message to lessen the suffering of humanity in this world. Scientific research proves that there are many health issues associated with eating meat.
Longevity and Blue Zones
One of the most telling indications that the SDA diet is beneficial and positively impacts health is found in the town of Loma Linda California, one of the established Blue Zones in the world. The long lifespan of blue zone populations is thought to be related to lifestyle factors, such as being active, resting regularly, and eating a nutritious diet rich in plant foods. Research on the blue zones found that 95% of people who lived to be at least 100 ate a plant-based diet that was rich in beans and whole grains. What’s more, it was shown that the Loma Linda Adventists outlive other Americans by about a decade.
Reduced Disease Risk
The Seventh-day Adventist diet has been linked to several health benefits, particularly those associated with the consumption of a vegetarian diet. The Seventh-day Adventist diet has many proven health benefits, especially when you follow a more plant-centric version. They also are less likely to develop:

Weight Management
Based on its dietary rules, it is safe to say it can be. First, it is a plant-based diet, and most plant-based diets have been successfully linked to weight loss because plant-based foods tend to be less energy-dense than animal-based foods. Third, it encourages exercise to burn extra calories. In light of this you can say that the diet can promote weight loss.
Practical Application of the SDA Diet

Considerations for Nutrient Intake
People who follow plant-based diets that entirely exclude animal products are at a higher risk of nutrient deficiency for vitamins D and B12, omega-3 fats, iron, iodine, zinc, and calcium. As such, the Adventist church recognizes the importance of eating a wide variety of nutrient-rich foods and including an adequate source of vitamin B12. Good sources include B12-fortified nondairy milks, cereals, nutritional yeast, or a B12 supplement.
